Overview
The ADS7830IPWR is a single-supply, low-power, 8-bit data acquisition device produced by Texas Instruments. It features a serial I2C interface and an 8-channel multiplexer, making it ideal for applications requiring the A/D converter to be close to the input source in remote locations and for applications requiring isolation. The device includes a sample-and-hold amplifier and an internal, asynchronous clock. It is available in a TSSOP-16 package and supports all three I2C modes: Standard, Fast, and High-Speed.
