ADC574 models in most applications, with internal
sampling, much lower power consumption, and capability
to operate from a single +5V supply.
The ADS574 is complete with 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
for 12-bit conversions is 25ms over the full operating
temperature range, including both acquisition and conversion.
Complete user control over the internal sampling function
facilitates elimination of external sample/hold
amplifiers in most existing designs.
The ADS574 requires +5V, with –12V or –15V optional,
depending on usage. No +15V supply is required.
Available packages include 0.3" or 0.6" wide
28-pin plastic DIPs and 28-lead SOICs.
