Product Details

The ADA4932-1 / ADA4932-2 are the next generation AD8132 with higher performance and lower noise and power consumption. They are an ideal choice for driving high performance ADCs as a single-ended-to-differential or differential-to-differential amplifier. The output common-mode voltage is user adjustable by means of an internal common-mode feedback loop, allowing the ADA4932-1 / ADA4932-2 output to match the input of the ADC. The internal feedback loop also provides exceptional output balance as well as suppression of even-order harmonic distortion products.

With the ADA4932-1 / ADA4932-2, differential gain configurations are easily realized with a simple external four-resistor feedback network that determines the closed-loop gain of the amplifier.

The ADA4932-1 / ADA4932-2 were fabricated using the Analog Devices, Inc., proprietary silicon-germanium (SiGe) complementary bipolar process, enabling it to achieve low levels of distortion and noise at low power consumption.

The low offset and excellent dynamic performance of the ADA4932-1/ADA4932-2 make them well suited for a wide variety of data acquisition and signal processing applications.

The ADA4932-1 is available in a 16-lead LFCSP, and the ADA4932-2 is available in a 24-lead LFCSP. The pinouts are optimized to facilitate the printed circuit board (PCB) layout and minimize distortion. The ADA4932-1/ADA4932-2 are specified to operate over the −40°C to +105°C temperature range; both operate on supplies between +3 V and ±5 V.

Applications

  • ADC drivers
  • Single-ended-to-differential converters
  • IF and baseband gain blocks
  • Differential buffers

ADIsimPE Linear and Mixed-Signal Circuit Simulator – Personal Edition

ADIsimPE, which is powered by SIMetrix/SIMPLIS, is a circuit simulation suite optimized for the design and development of analog and mixed signal circuits. SIMetrix mode is ideal for the simulation of general non-switching circuits. It provides full Pspice compatibility for use with industry-standard SPICE models. SIMPLIS (SIMulation Piecewise-Linear System) mode simulates the operation of switching circuits with vastly improved robustness, speed, and accuracy compared to standard SPICE. It is particularly useful for switching power supply, PLLs, and ADC/DAC applications.

ADI DiffAmpCalc™

ADI's new ADI DiffAmpCalc™ is a free, downloadable calculator for designing differential amplifier circuits. The tool is easy to use and features an interactive user interface to quickly get you up and running.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.  "Zero defects" for shipped products is always our goal.
