Texas Instruments ADS774KU

Description
The ADS774 is a 12-bit successive approximation analog-to-digital converter (ADC) that utilizes an innovative capacitor array (CDAC) implemented in low-power CMOS technology. It is a drop-in replacement for ADC574, ADC674, and ADC774 models in most applications, offering internal sampling, lower power consumption, and the ability to operate from a single 5V supply.
The ADS774 includes an internal clock, microprocessor interface, three-state outputs, and internal scaling resistors for input ranges of 0V to 10V, 0V to 20V, ±5V, or ±10V. It has a maximum throughput time of 8.5us over the full operating temperature range, encompassing both acquisition and conversion.
User control over the internal sampling function allows for the elimination of external sample/hold amplifiers in most existing designs.
