GENERAL DESCRIPTION

The AD7575 is a high speed 8-bit ADC with a built-in track/hold function. The successive approximation conversion technique is used to achieve a fast conversion time of 5 µs, while the built-in track/hold allows full-scale signals up to 50 kHz (386 mV/µs slew rate) to be digitized. The AD7575 requires only a single +5 V supply and a low cost, 1.23 V bandgap reference in order to convert an input signal range of 0 to 2 VREF.
