FEATURES  
DESCRIPTION  
2
Drop-In Replacement for the ADS774  
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.  
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  
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.  
Ensured AC and DC Performance  
Single +5V Supply Operation  
Low Power: 120mW Max  
Package Options: SO, 0.6in and 0.3in DIPs(1)  
APPLICATIONS  
Complete user control over the internal sampling  
function facilitates elimination of external sample/hold  
amplifiers in most existing designs.  
Medical Instrumentation  
Data Acquisition Systems  
Robotics  
Industrial Control  
Test Equipment  
The ADS774H requires +5V, with –15V optional. No  
+15V supply is required. Packages include a 28-pin  
SO, and 0.3in-wide or 0.6in-wide 28-pin DIPs(1).
