GENERAL DESCRIPTION
The AD7870/AD7875/AD7876 are fast, plete, 12-bit analog-to-digital converters (ADCs). These converters consist of a track-and-hold amplifier, an 8 μs successive approximation ADC, a 3 V buried Zener reference, and versatile interface logic. The ADCs feature a self-contained internal clock which is laser trimmed to guarantee...
