ADS7817PC
数据手册.pdf12Bit Differential Input Micro Power Sampling ANALOG-TO-DIGITAL CONVERTER
DESCRIPTION
The ADS7817 is a 12-bit, 200kHz sampling analog to-digital converter A/D that features a high impedance fully differential analog input. The reference voltage can be varied from 100mV to 2.5V, with a corresponding input-referred resolution between 49µV and 1.22mV.
The differential input, low power, automatic power down, and small size make the ADS7817 ideal for direct connection to transducers in battery operated systems, remote data acquisition, or multi-channel applications. The ADS7817 is available in a plastic mini-DIP-8, an SOIC-8, or an MSOP-8 package.
