The ADS774H is a 12-bit, successive-approximation analog-to-digital converter (ADC) that uses an innovative capacitor array (CDAC) implemented in low-power CMOS technology. This device is a drop-in replacement forthe ADS774, with internal sampling, much lower power consumption, and the ability to operate from a single +5V supply.
The ADS774H is complete with 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. The maximum throughput time is 8.5µs over the full operating temperature range, including both acquisition and conversion.
Complete user control over the internal sampling function facilitates elimination of external sample/hold amplifiers in most existing designs.
