Texas Instruments ADS574JE

Description
The ADS574 is a 12-bit successive approximation analog-to-digital converter (ADC) that utilizes an innovative capacitor array (CDAC) implemented in low-power CMOS technology. It is a drop-in replacement for ADC574 models in most applications, offering internal sampling, lower power consumption, and the ability to operate from a single 5V supply.
The ADS574 includes an internal clock, microprocessor interface, three-state outputs, and internal scaling resistors for input ranges of 0V to 10V, 0V to 20V, ±5V, or ±10V. It has a maximum throughput time of 25μs for 12-bit conversions over the full operating temperature range, including both acquisition and conversion.
The ADS574 provides complete user control over the internal sampling function, eliminating the need for external sample/hold amplifiers in most existing designs. It requires a 5V supply, with optional -12V or -15V depending on usage, and is available in 0.3" or 0.6" wide 28-pin plastic DIPs and 28-lead SOICs.
