General Description

The THS4551 fully differential amplifier offers an easy interface from single-ended sources to the differential output required by high-precision analogto-digital converters (ADCs).

Designed for exceptional dc accuracy, low noise, and robust capacitive load driving, this device is well suited for data acquisition systems where high precision is required along with the best signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR) through the amplifier and ADC combination.
