DESCRIPTION

The ADS7852 is an 8-channel, 12-bit analog-to-digi-

tal converter (A/D) complete with sample-and-hold,

internal 2.5V reference and a full 12-bit parallel output

interface. Typical power dissipation is 13mW at at

500kHz throughput rate. The ADS7852 features both

a nap mode and a sleep mode further reducing the

power consumption to 2mW. The input range is from

0V to twice the reference voltage. The reference volt-

age can be overdriven by an external voltage.

The ADS7852 is ideal for multi-channel applications

where low power and small size are critical. Medical

instrumentation, high-speed data acquisition and labo-

ratory equipment are just a few of the applications that

would take advantage of the special features offered

by the ADS7852. The ADS7852 is available in an

TQFP-32 package and is fully specified and guaran-

teed over the –40 C to +85 C temperature range.
