ADC700中文资料16-Bit Resolution With Microprocessor Interface A/D CONVERTER数据手册TI规格书

描述 Description

DESCRIPTION
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 17µs 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.FEATURES
