SBAS443 – AUGUST 2009 Microprocessor-Compatible Sampling CMOS ANALOG-TO-DIGITAL CONVERTER FEATURES 1 2 Drop-In Replacement for the ADS774 Complete Sampling ADC with Reference, Clock, and Microprocessor Interface Fast Acquisition and Conversion: 8.5µs Max Over Temperature Eliminates External Sample/Hold in Most Applications Ensured AC and DC Performance Single +5V Supply Operation Low Power: 120mW Max Package Options: SO, 0.6in and 0.3in DIPs(1) APPLICATIONS Medical Instrumentation Data Acquisition Systems Robotics Industrial Control Test Equipment Digital Signal Processing DSP Servo Control Control Inputs Bipolar Offset 20V Range 10V Range 2.5V Reference Input 2.5V Reference Output CDAC 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...
