Description

The ADA4932-1 / ADA4932-2 are the next generation AD8132with higher performance and lower noise and power consumption.They are an ideal choice for driving high performance ADCs asa single-ended-to-differential or differential-to-differentialamplifier. The output common-mode voltage is user adjustableby means of an internal common-mode feedback loop, allowingthe ADA4932-1 / ADA4932-2 output to match the input of theADC. The internal feedback loop also provides exceptionaloutput balance as well as suppression of even-order harmonicdistortion products.With the ADA4932-1 / ADA4932-2, differential gain configurationsare easily realized with a simple external four-resistor feedbacknetwork that determines the closed-loop gain of the amplifier.The ADA4932-1 / ADA4932-2 were fabricated using theAnalog Devices, Inc., proprietary silicon-germanium (SiGe)complementary bipolar process, enabling it to achieve low levelsof distortion and noise at low power consumption.The low offset and excellent dynamic performance of theADA4932-1/ADA4932-2 make them well suited for a widevariety of data acquisition and signal processing applications.The ADA4932-1 is available in a 16-lead LFCSP, and theADA4932-2 is available in a 24-lead LFCSP. The pinouts areoptimized to facilitate the printed circuit board (PCB) layoutand minimize distortion. The ADA4932-1/ADA4932-2 arespecified to operate over the −40°C to +105°C temperaturerange; 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 Line drivers
