Description for the ADS5421
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 0.5VPP, further improving the Signal-to-Noise Ratio (SNR) performance.
The ADS5421 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 ADS5421 is available in a small LQFP-64 package.
