ADA4922-1ARDZ

ADA4922-1 is a differential driver for 16bit to 18bit analogue-to-digital converter (ADC) that have differential input ranges up to ±20V. Configured as an easy-to-use, single-ended to differential amplifier, the ADA4922-1 requires no external components to drive ADC. The ADA4922-1 provides essential benefits such as low distortion and high SNR that are required for driving ADCs with resolutions up to 18bit. Typical application includes high voltage data acquisition systems, industrial instrumentation, spectrum analysis, ATE and medical instruments.
