ADA4932-1YCPZ-R7

The ADA4932 series is the next generation of the AD8132, offering higher performance, lower noise, and reduced power consumption. It is ideally suited for use as a single-ended-to-differential or differential-to-differential amplifier driving high-performance ADCs. Users can adjust the output common-mode voltage via the internal common-mode feedback loop to match the ADA4932-x outputs to the ADC inputs. The internal feedback loop also provides excellent output balance and suppresses even-order harmonic distortion products. For the ADA4932 series, differential gain configurations are easily implemented using a simple external feedback network consisting of four resistors, which determines the closed-loop gain of the amplifier. The ADA4932 series is fabricated using a silicon-germanium (SiGe) complementary bipolar process, enabling low distortion, low noise, and low power consumption. Low offset and excellent dynamic performance make the ADA4932-x particularly well suited for a wide range of data acquisition and signal processing applications. The ADA4932-1 is available in a 16-lead LFCSP, and the ADA4932-2 in a 24-lead LFCSP. The pinout is optimized to facilitate PCB layout and minimize distortion. The ADA4932 series is rated for operation over the -40°C to +105°C temperature range; both versions operate from +3 V to ±5 V supplies.
