ADADC71完整的高分辨率16位A/D转换器

　　The ADADC71 is a high resolution 16-bit hybrid IC analog-todigital converter including reference， clock， and laser-trimmed thin-film components. The package is a compact 32-pin hermetic ceramic DIP. The thin-film scaling resistors allow analog input ranges of ±2.5 V， ±5 V， ±10 V， 0 to +5 V， 0 to +10 V， and 0 to +20 V. Important performance characteristics of the device are maximum linearity error of ±0.003% of FSR， and maximum conversion time of 50 μs. This performance is due to innovative design and the use of proprietary monolithic DAC chips. Lasertrimmed thin-film resistors provide the linearity and wide temperature range for no missing codes. The ADADC71 provides data in parallel format with corresponding clock and status outputs. All digital inputs and outputs are TTL-compatible. The ADADC71 used to provide data in a serial format. The serial output function is no longer available after date code 0120.
