According to the company, 12-bit ADS7229 and ADS7230 and the 14-bit ADS7279 and ADS7280 combine a 1-MSPS successive approximation register (SAR) analog-to-digital (ADC) with inherent sample and hold and a conversion clock. The devices are designed for applications that require good AC and DC performance, high sampling rates and the low-power consumption, such as portable medical instruments, multi-channel data acquisition systems and automated test equipment.

According to the company, the ADS7229 and ADS7279 feature a single unipolar input for applications requiring a single data converter per channel. The ADS7230 and ADS7280 have a two-to-one input multiplexer that allows each ADC to digitize two channels, thereby reducing component count and board size. All four offer a SPI-compatible interface to minimize board space and simplify connection to the host device to enable increased channel densities and a smaller overall system footprint, said Texas Instruments.
