Description

The ADS5421 is a high-dynamic range 14-bit, 40MHz, pipelined Analog-to-Digital Converter (ADC). It includes a high-bandwidth linear track-and-hold amplifier that gives excellent spurious performance up to and beyond the Nyquist rate. The clock input can accept a low-level differential sine wave or square wave signal down to 0.5Vp-p, further improving the Signal-to-Noise Ratio (SNR) performance.

The ADS5421 has a 4Vp-p differential input range (2Vp-p • 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 ADS5421 is available in a small LQFP-64 package.
