The AD571 is a 10-bit successive approximation A/D converter that includes a DAC, voltage reference, clock, comparator, successive approximation register, and output buffers, all fabricated on a single chip. It can perform a full accuracy 10-bit conversion in 40 microseconds without the need for external components. The AD571 operates on supply voltages of +5V to +15V and -15V, and accepts analog inputs of 0V to +10V unipolar or ±5V bipolar, which can be externally selected. The conversion is initiated by driving the BLANK and CONVERT input low, and the output data is available when the conversion is completed.
