DESCRIPTION  
The ADS7887 is a 10-bit, 1.25-MSPS analog-to-digital converter (ADC), and the ADS7888 is a 8-bit, 1.25-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 2.35 V to 5.25 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.  
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 ADS7887 and ADS7888 are available in 6-pin SOT23 and SC70 packages and are specified for operation  
from -40°C to 125°C.
