AD7870JPZ

ANALOG DEVICES  AD7870JPZ  模数转换器, 12 bit, 100 kSPS, 双 +/-, 5 V, PLCC

The is a fast, complete 12-bit Analog-to-digital Converter ADC consist of a track-and-hold amplifier, an 8µs successive approximation ADC, a 3V buried Zener reference and versatile interface logic. The ADC features a self-contained internal clock which is laser trimmed to guarantee accurate control of conversion time. No external clock timing components are required, the on-chip clock may be overridden by an external clock if required. It features DC accuracy specifications, such as linearity, full-scale and offset error. It is fully specified for dynamic performance parameters including distortion and signal-to-noise ratio.
