ADS7887SDBVT .

The ADS7887SDBVT is a 10-bit Analog-to-digital Converter (ADC) includes a capacitor based SAR A/D converter with inherent sample and hold. The serial interface in each device is controlled by the CS and SCLK signals for glue-less connections with microprocessors and DSPs. The input signal is sampled with the falling edge of CS and SCLK is used for conversion and serial data output. The device operates from a wide supply range from 2.35 to 5.25V. The low power consumption of the device makes it suitable for battery-powered applications. The devices also include a power saving power-down feature for when the devices are operated at lower conversion speeds. The high level of the digital input to the device is not limited to device VDD. This means the digital input can go as high as 5.25V when device supply is 2.35V. This feature is useful when digital signals are coming from other circuit with different supply levels. Also this relaxes restriction on power up sequencing.
