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.

ADS7823-28EVM — ADS7823 和 ADS7828 評估模組

ADS7823-28EVM 是一款電路板,可與兩個 12 位元單/八通道、內部積體電路 (I2C)、序列介面類比轉數位轉換器 ADS7823 和 ADS7828 搭配使用。兩部裝置皆位在此單一印刷配線板上,因此可在單一 EVM 上同時運作。ADS7823-28EVM 可配置為使用 ADS7828 的內部參考,或是可配置板載跨接器的外部參考。使用一個額定 3.3 Vdc 的單電源供應器為 EVM 供電。此外可透過設定板載跨接器,提供可變數位電源電壓。
