ADS7953SBDBT .

The ADS7953SBDBT is a 8-bit multichannel Analog-to-digital Converter (ADC) includes a capacitor based SAR A/D converter with inherent sample and hold. The device accepts a wide analog supply range from 2.7 to 5.25V. Very low power consumption makes these devices suitable for battery-powered and isolated power supply applications. A wide 1.7 to 5.25V I/O supply range facilitates glue-less interfaces with the most commonly used CMOS digital hosts. The serial interface is controlled by CS and SCLK for easy connection with microprocessors and DSP. The input signal is sampled with the falling edge of CS. It uses SCLK for conversion, serial data output and reading serial data in. The devices allow auto sequencing of preselected channels or manual selection of a channel for the next conversion cycle. There are two software selectable input ranges, four individually configurable GPIOs and two programmable alarm thresholds per channel.
