Name: THS4131 Fully Differential Amplifier Size: 45mm X 34mm Supply Voltage Range: 5V Single Supply ±15V Dual Supply

This module can implement single-ended to differential, single-ended input, and double-ended output. Has high performance, low noise, wide power supply voltage range and other advantages.

The THS413x consists of a true fully differential signal path from input to output. This design produced excellent common-mode noise suppression wells that improved total harmonic distortion.

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.
