8-Bit, 8-Channel Sampling A/D Converter with I2C Interface

 

Description

The ADS7830 is a single-supply, low-power, 8-bit data acquisition device that features a serial I2C interface and an 8-channel multiplexer. The Analog-to-Digital (A/D) converter features a sample-and-hold amplifier and internal, asynchronous clock. The combination of an I2C serial, 2-wire interface and micropower consumption makes the ADS7830 ideal for applications requiring the A/D converter to be close to the input source in remote locations and for applications requiring isolation. The ADS7830 is available in a TSSOP-16 package.
