8-Bit Successive Approximation Analog-to-Digital Converter

The AD570 is an 8-bit successive approximation A/D converter consisting of a DAC Voltage Reference Clock Comparator successive approximation Register and output buffers-all fabricated on a single chip. No external components are required to perform a full accuracy 8-bit conversion in 25 s.
The AD570 incorporates the most advanced integrated circuit design and processing technology available today. I2 L (integrated injection logic) processing in the fabrication of the SAR function along with laser trimming of the high stability SiCr thin-film resistor ladder network at the wafer stage (LWT) and a temperature compensated, subsurface Zener reference insures full 8-bit accuracy at low cost.
Operating on supplies of +5 V and -15 V, the AD570 accepts Analog inputs of 0 V to +10 V unipolar of 5 V bipolar, externally selectable. As the BLANK and CONVERT input is driven low, the three-state outputs go into the high impedance state and a conversion commences. Upon completion of the conversion, the DATA READY line goes low and the data appears at the output. Pulling the BLANK and CONVERT input high three states the outputs and readies the device for the next conversion. The AD570 executes a true 8-bit conversion with no missing codes in approximately 25 s.
The AD570 is available in two version; the AD570J is specified for the 0C to +70C temperature range, the AD570S for -55C to +125C. Both guarantee full 8-bit accuracy and no missing codes over their respective temperature ranges.
