Overview

The ADA4938-1ACPZ-R7 / ADA4938-2 are low noise, ultralow distortion,high speed differential amplifiers. It is an ideal choice fordriving high performance ADCs with resolutions up to 16 bitsfrom dc to 27 MHz, or up to 12 bits from dc to 74 MHz. Theoutput common-mode voltage is adjustable over a wide range,allowing the ADA4938-1/ADA4938-2 to match the input of theADC. The internal common-mode feedback loop also providesexceptional output balance as well as suppression of even-orderharmonic distortion products.

The ADA4938-1ACPZ-R7 (single amplifier) is available in a Pb-free,3 mm × 3 mm, 16-lead LFCSP. The ADA4938-2 (dualamplifier) is available in a Pb-free, 4 mm × 4 mm, 24-leadLFCSP. The pinouts have been optimized to facilitate layout andminimize distortion. The devices are specified to operate overthe extended industrial temperature range of −40°C to +85°C.
