The ADS774JU is a 12-bit Analog-to-digital Converter (ADC) using an innovative capacitor array (CDAC) implemented in low-power CMOS technology. The microprocessor-compatible sampling successive approximation ADC is complete with internal clock, microprocessor interface, 3-state outputs and internal scaling resistors for input ranges of 0 to 10/20V and ±5/10V. 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.
