Texas Instruments ADS5231 12-Bit Analog-to-Digital Converters

Texas Instruments ADS5231 Analog-to-Digital Converters (ADCs) are dual, 40MSPS high-speed, high dynamic range, 12-bit pipelined ADCs. These converters include a high-bandwidth sample-and-hold amplifier that gives excellent spurious performance up to and beyond the Nyquist rate. The differential nature of the sample-and-hold amplifier and ADC circuitry minimizes even-order harmonics and gives excellent common-mode noise immunity.
