Description

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 for the 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. The ADS774H requires +5V, with -15V optional. No +15V supply is required. Packages includea 28-pin SO, and 0.3in-wide or 0.6in-wide 28-pin DIPsDIP-28 package is product preview.
