The ADA4937-x is a low noise, ultralow distortion, high speed differential amplifier. It is an ideal ADC driver and can be used in applications such as single-ended-to-differential converters, IF and baseband gain blocks, differential buffers, and line drivers.
The ADA4937-x family provides ultralow distortion, high‑speed differential amplification for driving high‑performance ADCs up to 16‑bit resolution. They support single‑ended‑to‑differential conversion, line‑driver functions, and are suitable for data‑acquisition and signal‑processing applications.
Key features include a 3 dB bandwidth of up to 1.9 GHz (5 V operation), a typical slew rate of 6000 V/µs, input voltage noise of 2.2 nV/√Hz, and operation over an automotive temperature range (‑40 °C to +105 °C). The devices are offered in 16‑lead (ADA4937‑1) and 24‑lead (ADA4937‑2) LFCSP packages with exposed pads for thermal management.
