DESCRIPTION
The ADS574 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 models in most applications, with internal
sampling, much lower power consumption, and capa-
bility to operate from a single +5V supply.
The ADS574 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
for 12-bit conversions is 25
μ
s over the full operating
temperature range, including both acquisition and con-
version.
Complete user control over the internal sampling func-
tion facilitates elimination of external sample/hold
amplifiers in most existing designs.
The ADS574 requires +5V, with –12V or –15V op-
tional, depending on usage. No +15V supply is re-
quired. Available packages include 0.3" or 0.6" wide
28-pin plastic DIPs and 28-lead SOICs.
