ADS5422 (ACTIVE)

14-Bit, 62-MSPS Analog-to-Digital Converter (ADC)

 

Description

The ADS5422 is a high-dynamic range, 14-bit, 62MSPS, pipelined Analog-to-Digital Converter (ADC). It includes a high-bandwidth linear track-and-hold amplifier that gives good spurious performance up to the Nyquist rate. The clock input can accept a low-level differential sine wave or square wave signal down to 0.5VPP, further improving the Signal-to-Noise Ratio (SNR) performance.

The ADS5422 has a 4VPP differential input range (2VPP • 2 inputs) for optimum Spurious-Free Dynamic Range (SFDR). The differential operation gives the lowest even-order harmonic components. A lower input voltage can also be selected using the internal references, further optimizing SFDR.

The ADS5422 is available in an LQFP-64 package.
