Overview

Description
The AD7781 is a low-power, 20-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC) designed for bridge sensor applications. It features an on-chip programmable gain amplifier (PGA) with gains of 1 or 128, an internal clock oscillator, and a power-down mode. The AD7781 operates with a power supply from 2.7 V to 5.25 V and is available in a narrow body, 14-lead SOIC package and a 16-lead TSSOP package.

Features
Pin-programmable filter response
Update rate: 10 Hz or 16.7 Hz
Pin-programmable in-amp gain
Pin-programmable power-down and reset
Status function
Internal clock oscillator
Internal bridge power-down switch
Current: 115 μA typical (gain = 1), 330 μA typical (gain = 128)
Simultaneous 50 Hz/60 Hz rejection
Power supply: 2.7 V to 5.25 V
-40°C to 105°C temperature range
Independent interface power supply
2-wire serial interface (read-only device)
SPI compatible
Schmitt trigger on SCLK

Applications
Weigh scales
Pressure measurement
Industrial process control
Portable instrumentation
