The ADS7828 is a single-supply low-power 12-bit data acquisition device that features a serial I2C interface and an 8-channel multiplexer. The analog-to-digital converter (ADC) features a sample-and-hold amplifier and internal asynchronous clock. The combination of an I2C serial 2-wire interface and micropower consumption makes the ADS7828 ideal for applications requiring the ADC to be close to the input source in remote locations and for applications requiring isolation. The ADS7828 is available in a TSSOP-16 package.
