Low Power, 16-/24-Bit Sigma-Delta ADC

for Bridge Sensors

AD7796/AD7797

GENERAL DESCRIPTION

FEATURES

RMS noise: 65 nV

Instrumentation amp

Temperature sensor

Internal clock oscillator

Simultaneous 50 Hz/60 Hz rejection

Update rate: 4.17 Hz to 123 Hz

Current: 250 μA typ

The AD7796/AD7797 are complete, analog front ends for high

precision, bridge sensor applications such as weigh scales. The

AD7796/AD7797 contain a Σ-Δ ADC capable of 16-/24-bit

resolution, respectively. The on-chip instrumentation amplifier

has a fixed gain of 128, allowing small amplitude signals such as

those from bridge sensors to be directly interfaced to the ADC.

Each part has one differential input and contains a temperature

sensor that is internally connected to the ADC. This sensor can

be used to perform temperature compensation of the bridge.

Power-down: 1 μA

Power supply: 2.7 V to 5.25 V

–40°C to +85°C temperature range

Independent interface power supply

16-lead TSSOP

The devices can be operated with the internal clock or an

external clock. The output data rate from the parts is software-

programmable and can be varied from 4.17 Hz to 123 Hz.

INTERFACE

The AD7796/AD7797 operate with a power supply from 2.7 V

to 5.25 V. Each part consumes a current of 250 μA typical and is

housed in a 16-lead TSSOP.
