The ADA4940-1/ADA4940-2 are low noise, low distortion, ultralow power differential amplifiers ideal for driving low power, high resolution, high performance SAR type and Σ - A delta analog-to-digital converter (ADC) with only 1.25 mA of quiescent current. The adjustable output common-mode level enables the ADA4940-x to match the input common-mode voltage of multiple ADCs. An internal common-mode feedback loop also provides excellent output balance and rejection of even-order harmonic distortion products.

For the ADA4940-1/ADA4940-2, the differential gain configuration is easily achieved using a simple external feedback network consisting of 4 resistors, which determines the closed-loop gain of the amplifier. Manufactured on Analog Devices' complementary bipolar process, the ADA4940-1/ADA4940-2 achieve very low distortion levels with an input voltage noise of only 3.9 nV/√Hz. Low DC offset and excellent dynamic performance make the ADA4940-1/ADA4940-2 ideal for a variety of data acquisition and signal processing applications.

The ADA4940-1 is available in a 3 mm × 3 mm, 16-lead lead-free LFCSP package. The ADA4940-2 is available in a 4 mm × 4 mm, 24-lead lead-free LFCSP package. The pinout is optimized to facilitate printed circuit board (PCB) layout and minimize distortion. The ADA4940-1 and ADA4940-2 are specified for an operating temperature range of ~40°C to +125°C.
