DESCRIPTION
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.
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.
Complete user control over the internal sampling func-
tion facilitates elimination of external sample/hold
amplifiers in most existing designs.
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.
