Integrated AMR Angle Sensor includes signal conditioning

The ADA4571 anisotropic magnetoresistive (AMR) sensor with integrated signal conditioning amplifiers and ADC drivers produces two analog outputs that indicate the angular position of the surrounding magnetic field. Comprising an AMR sensor and a fixed gain (G = 40 nominally) instrumentation amplifier, it delivers clean, amplified cosine and sine output signals related to the angle of a rotating magnetic field. The output voltage range is ratiometric to the supply voltage. The sensor consists of two Wheatstone bridges offset by 45. A rotating magnetic field in the x-y sensor plane delivers two sinusoidal output signals at twice the frequency of the angle (α) between sensor and magnetic field direction. Within a homogeneous field in the x-y plane, the output signals are independent of the physical placement in the z direction. Operating with a 2.7-V to 5.5-V supply, the device draws 4.5 mA in normal mode and 15 A in power-down mode. The B-grade is specified from 40C to +125C; the W‑grade, qualified for automotive applications, is specified to +150C.

High-voltage Input Protection Device

The ADM1270 current-limiting controller provides inrush current limiting and overcurrent protection for modular or battery-powered systems. When PC boards are inserted into a live backplane, discharged bypass capacitors draw large transient currents from the backplane power bus. These transients can permanently damage connector pins and cause voltage drops that can reset other devices. This device controls the inrush current via an external P-channel FET. An additional external P-channel FET can be controlled to protect the system from a reverse polarity input supply, preventing reverse current flow that can damage the device or the load. Operating on a 4-V to 60-V supply, the ADM1270 draws 360 A. Available in16-lead LFCSP and QSOP packages, it is specified from 40C to +125C and priced at $2.49 in 1000s.

Noise performance under blocking is comparable to narrowband passive mixer designs. High-linearity IF buffer amplifiers provide 9-dB typical power conversion gain, and can be matched to a wide range of output impedances. The PLL architecture supports both integer-N and fractional-N operation and can generate the entire 200-MHz to 2700-MHz LO frequency range using an external reference input frequency anywhere in the 12-MHz to 320-MHz range. An external loop filter provides flexibility in trading off phase noise vs. acquisition time. To reduce fractional spurs in fractional-N mode, a sigma-delta (Σ-Δ) modulator controls the post-VCO programmable divider. The VCO consists of multiple VCO cores. All features are controlled via a 3-wire SPI. Operating on 3.7-V and 5-V supplies, the ADRF6612 dissipates 2.7 W in high-performance mode and 2.0 W in high-efficiency mode.

8:1 and Dual 4:1 Multiplexers with User-defined Fault Protection and Detection

The ADG5248F and ADG5249F are 8:1 and dual 4:1 (respectively) analog multiplexers. The ADG5248F switches one of eight inputs to a common output and the ADG5249F switches one of four differential inputs to a common differential output. An EN input on both devices enables or disables the device and each channel conducts equally well in both directions when on, and each channel has an input signal range that extends to the supplies. When no power supplies are present, the channel remains in the off condition, and the channel inputs are high impedance. Input signal levels up to +55 V or −55 V relative to ground are blocked in both the powered and unpowered conditions, and the devices are immune to latch-up under any circumstances. The low capacitance (19 pf/14 pf respectively) and charge injection (QINJ) of 0.8 pC,   make these switches ideal solutions for data acquisition and sample-and-hold applications, where low glitch switching and fast settling times are required. The ADG5248F and ADG5249F operate over the −40C to +125C temperature range, and are packaged in 20-lead TSSOP. Pricing is $4.55 in 1000s.

Dual 10-Ω SPDT Switch offers fault protection and detection

The ADG5436F contains two independently controlled single-pole/double-throw (SPDT) switches. All switches can be disabled by bringing the enable input low. The switches exhibit break-before-make switching action, making them suitable for multiplexer applications. They conduct equally well in both directions when on, and have an input signal range that extends to the supplies. The digital inputs are compatible with 3-V logic inputs over the full operating supply range. Input signal levels up to +55 V or 55 V relative to ground are blocked in both the powered and unpowered condition. When no power supplies are present, the switch remains in the off condition, and the switch inputs are high impedance. Under normal operating conditions, if the analog input signal on any Sxx pin exceeds VDD or VSS by a threshold voltage, VT, the switch turns off. Operating on a single 8-V to 44-V supply or dual 5-V to 22-V supplies, the ADG5436F draws 1.2 mA in fault mode and 0.9 mA in normal mode. Available in a 16-lead TSSOP package, it is specified from 40C to +125C and priced at $3.86 in 1000s.

Quad Channel Protector provides user-defined fault protection and detection

The ADG5462F contains four overvoltage protected channels. When placed in series with the signal path, it protects sensitive components from overvoltage faults, whether powered or unpowered, making it ideal for use in applications where correct power supply sequencing cannot always be guaranteed. The primary supply voltages define the on-resistance profile, while the secondary supply voltages define the voltage level at which the overvoltage protection engages. When no power supplies are present, the channel remains in the off condition, and the channel inputs are high impedance. Under normal operating conditions, if the analog input signal on any Sx pin exceeds the positive or negative fault voltage by a threshold voltage, the channel turns off and the pin becomes high impedance. If the drain response pin is driven low, the drain pin (Dx) is pulled to the secondary supply voltage that was exceeded. Input signal levels up to −55 V or +55 V relative to ground are blocked in both the powered and unpowered conditions. The low on-resistance of these switches, combined with the on-resistance flatness over a significant portion of the signal range make them ideal for data acquisition and instrumentation applications where excellent linearity and low distortion are critical. Operating on a single 8-V to 44-V supply or dual 5-V to 22-V supplies, the ADG5462F draws 1.2 mA in fault mode and 0.9 mA in normal mode.
