The ADS7886 is a 12-bit, 1-MSPS analog-to-digital converter (ADC). The device 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 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 device operates from a wide supply range from 2.35 V to 5.25 V. The low power
consumption of the device makes it suitable for battery-powered applications. The device also
includes a power down feature for power saving 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 5.25 V when device
supply is 2.35 V. This feature is useful when digital signals are coming from other circuit with
different supply levels. Also this relaxes restriction on power-up sequencing.
The ADS7886 is available in 6-pin SOT-23 and SC70 packages and is specified for operation
from –40°C to 125°C.
