ADI AD7890ARZ-10

数据采集系统（DAS）812 b117kSPI5V-40°C ~ 85°C表面贴装型24-SOIC（0.295"，7.50mm 宽）

Overview

The AD7890ARZ-10 is a LC²MOS 8-channel 12-bit Serial Data Acquisition System contains an input multiplexer, an on-chip track/hold amplifier, a high speed 12-bit ADC, a 2.5V reference and a high speed serial interface. The multiplexer on the part is independently accessible. This allows the user to insert an anti-aliasing filter or signal conditioning, if required, between the multiplexer and the ADC. This means that one anti-aliasing filter can be used for all 8-channel. Connection of an external capacitor allows the user to adjust the time given to the multiplexer settling to include any external delays in the filter or signal conditioning circuitry. Output data from the converter is provided via a high speed bidirectional serial interface port. The part contains an on-chip control register, allowing control of channel selection, conversion start and power-down via the serial port.
