Name: AD8130 Differential Amplifier Size: 43mm X 38mm Supply voltage range: ±5V~±12V

The differential-to-single-ended amplifier, which has a 270-MHz bandwidth and a very high common-mode rejection ratio (CMRR) at high frequencies, can also be effectively used as a high-speed instrumentation amplifier or to convert a differential signal to a single-ended signal.

Differential amplifiers can process single-ended inputs as interactive differential outputs or treat differential inputs as differential outputs. These amplifiers have two independent feedback loops that control the differential and common-film output voltages, respectively.
