They are an ideal choice for driving high performance ADCs as a single-ended-to-differential or differential-to-differential amplifier. The output mon-mode voltage is user adjustable by means of an internal mon-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 (Si Ge) plementary FUNCTIONAL BLOCK DIAGRAM Figure 1. ADA4932-1 Figure 2. ADA4932-2 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...
