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 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.
