The ADC700 is a complete 16-bit resolution successive approximation analog-to-digital converter.

The reference circuit, containing a buried zener, is laser-trimmed for minimum temperature coefficient. The clock oscillator is current-controlled for excellent stability over temperature. Gain and Zero errors may be externally trimmed to zero. Analog input ranges of 0V to +5V, 0V to +10V, 0V to +20V, ±2.5V, ±5V, and ±10V are available.

The conversion time is 17ms max for a 16-bit conversion over the three specification temperature ranges. After a conversion, output data is stored in a latch separate from the successive approximation logic. This permits reading data during the next conversion, a feature that provides flexible interface timing, especially for interrupt-driven interfaces. Data is available in two 8-bit bytes from TTL-compatible three-state output drivers. Output data is coded in Straight Binary for unipolar input signals and Bipolar Offset Binary or Twos complement for bipolar input signals.

BOB or BTC is selected by a logic function available on one of the pins. The ADC700 is available in commercial, industrial and military temperature ranges. It is packaged in a hermetic 28-pin side-braze ceramic DIP.
