ADS7230 Description
The ADS7229 is a low-power, 12-bit, 1MSPS analog-to-digital converter (ADC) with a unipolar input. The device includes a 12-bit capacitor-based successive approximation register (SAR) ADC with inherent sample-and-hold. The ADS7230 is based on the same core and includes a 2-to-1 input MUX with a programmable TAG bit output option.
