GENERAL DESCRIPTION
The AD7782 is a complete analog front end for low-frequency
measurement applications. The 24-bit sigma-delta ADC contains
two fully differential analog input channels that can be config-
ured with a gain of 1 or 16 allowing full-scale input signal ranges
of
±2.56 V or ± 160 mV from a +2.5 V differential reference
input.
The AD7782 has an extremely simple, read-only digital interface
which can be operated in master mode or slave mode. There are
no on-chip registers to be programmed. The input signal range
and input channel selection are configured using two external pins.

MICROWIRE is a trademark of National Semiconductor Corporation.

INTERFACE
The device operates from a 32.768 kHz crystal with an on-chip PLL
generating the required internal operating frequency. The output
data rate from the part is fixed via the master clock at 19.79 Hz and
provides simultaneous 50 Hz and 60 Hz rejection at this update
rate. Eighteen-bit p-p resolution can be obtained at this update rate.
The part operates from a single 3 V or 5 V supply. When operating
from 3 V supplies, the power dissipation for the part is 3.9 mW.
The AD7782 is available in a 16-lead TSSOP package.
Another part in the AD778x family is the AD7783. It is similar
to the AD7782 except it has two integrated current sources and
only one differential input channel.
