DESCRIPTIONThe 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.
