The ADV7170 & ADV7171 interface digital video systems (DVD, set-top boxes, PCs, digital cameras) to standard analog TVs and VCRs. New super sub-alias filter (SSAF™) technology has resulted in industry-leading "professional studio" video quality with smart power management for mobile PCs and battery-powered applications (100 nA in power-down). Features include multi-standard switchable 4-DAC video output, SCART, S-Video, component (YUV) video, composite video, WSS, & CGMS-A.
They interface gluelessly to MPEG I & MPEG II video decoders. They differ only in that ADV7170 supports Macrovision Anti-Taping, Rev. 7.01. Sleep-mode current is <1.0 µA. They are specified for 3.3- and 5-volt single supplies and are housed in 44-lead PQFP and TQFP packages, for 0 to +70°C. An evaluation board is available. Device prices (10,000) start at $4.50.
The AD725 is a very low cost general-purpose RGB to NTSC/PAL encoder; it converts red-green-blue color component signals to corresponding luminance and chrominance values in accordance with either NTSC or PAL standards. The outputs are also combined on-chip to provide a composite video output. All three outputs are available at twice the standard voltage level for convenience in driving 75-
Included is a luminance trap (YTRAP) pin to provide a means of reducing luminance-associated cross color. The device is 5-V single-supply operated and can be powered down to less than 1 µA of current consumption; TTL-compatible logic levels can support logic requirements of 3-V CMOS systems. The device is packaged in 16-lead SOIC Price (1000s) is $4.25.
The AD9224 and AD9225 are 12-bit, 40- and 25 MSPS complete A/D converters. They are pin-compatible upgrades of the AD922x series with sample rates from 1.25 to 10 MSPS. They offer price and performance advantages in new and emerging applications in communications, medical imaging, ultra-
sound, instrumentation, scanners, and signal-capture.
Features of the AD9224/25 include SFDRs of 75/85-dB, SINAD of 67.5/70.5 dB, SNR of 69.1/71 dB, low power dissipation (376/280 mW), differential inputs, wide input bandwidth (120/105 MHz), 10.9/11.4 ENOB (effective number of bits), and 12-bit no-missing-codes. They are housed in 28-pin SOIC and SSOP packages, and are specified for operation from 0 to +70°C (AD9224) and -40 to +85°C (AD9225). Prices (1000s) are $18.66 and $15.35.
The AD22151 is a monolithic integrated circuit in an 8-lead SOIC package that outputs an analog voltage proportional to magnetic field strength perpendicular to the plane of the package (positive top-to-bottom). The Hall-effect sensor is centrally located, with an area of approximately 0.25 mm2. The device operates over a range of -40 to +150°C, with nominal sensitivity of 0.4 mV/gauss, offset error of ±6 gauss over temperature, and 1% gain error over temperature. Offset and gain are adjustable, and first-order temperature compensation can be adjusted to adapt to commonly used magnetic materials. The output is ratiometric with supply voltage.
Principal applications are in automotive and industrial settings, mainly for position sensing of such elements as throttles, pedals, valves, and suspensions. Nominal supply voltage is +5 V. Price is <$5.
Isolates dc-20-MHz 5-V logic
The AD261 isolates 5 microcontroller input or output signal lines from 5 field or system destinations with common supplies. The six optional versions of the device establish the channel mix, i.e., how many of the lines are inputs and how many are outputs. Although designed to isolate µPs from ADCs and DACs, the AD261 can be used for isolating just about any 5-V logic signal from dc to 20 MHz. Current consumption (both sides--system and field) ranges from <8 mA at <1 MHz to 26 mA at 20 MHz.
Typical applications are in process control, factory automation, motor drives, utility monitoring, etc. The device has UL1950, IEC950, and EN60950 certification, and VDE and CE are pending. It is housed in a 22-pin plastic DIP, and requires isolated +5-V supplies for input and output circuitry. It is available in 1.75 & 3.5 kV rms versions, priced at $9.60 & $11.30 (1000).
The AD8307 is a high-speed logarithmic amplifier designed to convert high-
frequency signals (20 Hz to 500 MHz) into their demodulated low-frequency (dc) equivalents. The output is proportional to the logarithm of the input voltage or power. Typical applications are in determining the strength of wide-dynamic-range rf signals (i.e., received signal strength indication--RSSI), and in wide-dynamic-range rf power control, especially for cellular/PCS base stations. It is also useful in converting rf signal levels to true decibels in network and spectrum analyzers.
Available in 8-pin PDIP or SOIC, it is temperature stable, easy to use, and operates on +3 to +5-V supplies. It is accurate to within ±1dB, and it handles signals with dynamic ranges of up to 92 dB. An evaluation board is available. The device's price in 1000s is $5.25.
The AD7376 is a single-channel, 128-position digitally controlled potentiometer, available in resistance values of 10k
The potentiometer setting is established via an SPI-compatible 3-wire serial interface. Settling time is 4 µs and THD is 0.005%. Power dissipation is 30 mW max. The AD7376 is available in 14-lead PDIP and TSSOP, as well as 16-lead widebody SO packages for operation from -40 to +85°C. Price (1000s) is $2.57.
The AD6190 is a complete RF/IF transceiver for use in 900-MHz spread-spectrum wireless systems. A big leap forward in high-integration RF chips, it is a real "radio-on-a-chip" device, including transmit, receive, and local oscillator functions. It is designed for use in conjunction with the Zilog Zphone baseband digital processor (or equivalent). With a processor and a few additional
low-cost components and filters, it forms
the basis of a high-performance, low-
cost spread-spectrum cordless telephone (reference design available).
The AD6190 is designed for operation with-
in a battery voltage range of 3.0 to 4.6 V and is specified at 3.3 V. It typically draws 93 mA in Transmit, 59 mA in Receive, and 270 µA in Sleep mode. Housed in SSOP-28, its operating temperature range is -25 to +85°C. Price in very large quantity is well below $5.00.
These are the parts of the AD20msp910 ADSL modem chip set:--an easy-to-use chipset that meets industry standards, including ANSI T1.413, ETSI TR328, and ITU G.dmt and G.lite.
The AD6435 is the interface/framer that connects the chipset to the rest of the system. It buffers the data, formats and frames it to the ADSL standard and also performs FEC. The AD6436 is the "engine" of the DMT chipset. It takes clean data from the AD6435 and does all of the digital modulation/ demodulation, signal processing, equalizing, filtering, and related tasks. The AD6437, the codec, or mixed-signal stage in the ADSL chipset, includes 12-bit Tx & Rx signal paths, with 70-dB performance and sampling rates that support multi-MHz bandwidths or oversampling. This part can be used separately as a general-purpose codec.
