ADS7885 说明

The ADS7884 is a 10-bit, 3-MSPS analog-to-digital converter (ADC), and the ADS7885 is a 8-bit, 3-MSPS ADC. The devices include 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 glueless 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 devices operate from a wide supply range from 2.7 V to 5.5 V. The low power consumption of the devices make them suitable for battery-powered applications. The devices also include a power saving powerdown feature for when the devices are operated at lower conversion speeds.
