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.
