ADS774  
Microprocessor-Compatible Sampling  
CMOS ANALOG-to-DIGITAL CONVERTER  
FEATURES  
DESCRIPTION  
REPLACES ADC574, ADC674 AND ADC774  
The ADS774 is a 12-bit successive approximation  
analog-to-digital converter using an innovative  
capacitor array (CDAC) implemented in low-power  
CMOS technology. This is a drop-in replacement for  
ADC574, ADC674, and ADC774 models in most  
applications, with internal sampling, much lower power  
consumption, and the ability to operate from a single  
+5V supply.  
FOR NEW DESIGNS  
COMPLETE SAMPLING A/D WITH  
REFERENCE, CLOCK AND  
MICROPROCESSOR INTERFACE  
FAST ACQUISITION AND CONVERSION:  
8.5µs max OVER TEMPERATURE  
ELIMINATES EXTERNAL SAMPLE/HOLD  
The ADS774 is complete with internal clock, micro-  
processor 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.  
IN MOST APPLICATIONS  
GUARANTEED AC AND DC PERFOR-  
MANCE  
SINGLE +5V SUPPLY OPERATION  
LOW POWER: 120mW max  
Complete user control over the internal sampling func-  
tion facilitates elimination of external sample/hold  
amplifiers in most existing designs.  
PACKAGE OPTIONS: 0.6" and 0.3" DIPs,  
SOIC  
The ADS774 requires +5V, with –15V optional. No  
+15V supply is required. Available packages include  
0.3" or 0.6" wide 28-pin plastic DIP and 28-pin SOICs.
