The AD9246S is a monolithic, single 1.8 V supply, 14-bit, 125 MSPS analog-to-digital converter (ADC), featuring a high performance sample-and-hold amplifier (SHA) and on-chip voltage reference. The product uses a multistage differential pipeline architecture with output error correction logic to provide 14-bit accuracy at 125 MSPS data rates and guarantees no missing codes over the full operating temperature range.

The wide bandwidth, truly differential SHA allows a variety of user-selectable input ranges and offsets, including single-ended applications. It is suitable for multiplexed systems that switch full-scale voltage levels in successive channels and for sampling single-channel inputs at frequencies well beyond the Nyquist rate. Combined with power and cost savings over previously available ADCs, the AD9246S is suitable for applications in communications, imaging, and medical ultrasound.

A differential clock input controls all internal conversion cycles. A duty cycle stabilizer (DCS) compensates for wide variations in the clock duty cycle while maintaining excellent overall ADC performance. The digital output data is presented in offset binary, Gray code, or twos complement formats. A data output clock (DCO) is provided to ensure proper latch timing with receiving logic.

The AD9246S is available in a 48-lead Quad flat pack and is specified over temperature range of −55°C to +125°C.

Product Highlights

  1. The AD9246S operates from a single 1.8 V power supply and features a separate digital output driver supply to accommodate 1.8 V to 3.3 V logic families.
  2. The patented SHA input maintains excellent performance for input frequencies up to 225 MHz.
  3. The clock DCS maintains overall ADC performance over a wide range of clock pulse widths.
  4. A standard serial port interface supports various product features and functions, such as data formatting (offset binary, twos complement, or Gray coding), enabling the clock DCS, power-down, and voltage reference mode.
  5. The AD9246S is pin-compatible with the AD9233, allowing a simple migration from 12 bits to 14 bits

Applications

  • Ultrasound equipment
  • IF sampling in communications receivers IS-95, CDMA-One, IMT-2000
  • Battery-powered instruments
  • Hand-held scopemeters
  • Low cost digital oscilloscopes

FPGA-Based Data Capture Kit

FPGA-Based Data Capture Kit

Features and Benefits

  • 64kB FIFO Depth
  • Works with single and multi-channel ADCs
  • Use with VisualAnalog® software
  • Based on Virtex-4 FPGA
  • May require adaptor to interface with some ADC eval boards
  • Allows programming of SPI control Up to 644 MSPS SDR / 800MSPS DDR Encode Rates on each channel
  • DDR Encode Rates on each channel

Product Detail

The HSC-ADC-EVALCZ high speed converter evaluation platform uses an FPGA based buffer memory board to capture blocks of digital data from the Analog Devices high speed analog-to-digital converter (ADC) evaluation boards. The board is connected to the PC through a USB port and is used with VisualAnalog® to quickly evaluate the performance of high speed ADCs. The evaluation kit is easy to set up. Additional equipment needed includes an Analog Devices high speed ADC evaluation board, a signal source, and a clock source. Once the kit is connected and powered, the evaluation is enabled instantly on the PC.

Features and Benefits

  • Simple USB port interface (2.0)
  • Supporting ADCs with serial port interfaces (SPI)
  • On-board regulator circuit, no power supply required 6 V, 2 A switching power supply included
  • Real-time FFT and time domain analysis
    Analyze SNR, SINAD, SFDR, and harmonics
  • Installed with AD9246S-EMX engineering unit (same form, fit and function over full temp range as flight units)

Product Detail

The EVAL-AD9246S supports the AD9246S 125 MSPS Space Grade Analog-to-Digital Converter. The evaluation board when paired with the HSC-ADC-EVALCZ capture board provides a platform to evaluate the performance of the AD9246S. The analog input and clock signals can be brought onto the board through edge-mounted SMA connectors. The headers on the board can be used to select the use of either the on-board power solution (default) or the use of an external power supply (jumpers removed).
