ADS7816

12-Bit High Speed Micro Power Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● 200kHz SAMPLING RATE

The ADS7816 is a 12-bit, 200kHz sampling analog-

to-digital converter. It features low power operation

with automatic power down, a synchronous serial

interface, and a differential input. The reference volt-

age can be varied from 100mV to 5V, with a corre-

sponding resolution from 24µV to 1.22mV.

● MICRO POWER:

1.9mW at 200kHz

150µW at 12.5kHz

● POWER DOWN: 3µA Max

● 8-PIN MINI-DIP, SOIC, AND MSOP

● DIFFERENTIAL INPUT

Low power, automatic power down, and small size

make the ADS7816 ideal for battery operated systems

or for systems where a large number of signals must be

acquired simultaneously. It is also ideal for remote

and/or isolated data acquisition. The ADS7816 is

available in an 8-pin plastic mini-DIP, an 8-lead SOIC,

or an 8-lead MSOP package.
