G = 50, CMOS Sensor Amplifier

with Current Excitation

AD8290

FEATURES

GENERAL DESCRIPTION

Supply voltage range: 2.6 V to 5.5 V

Low power

1.2 mA + 2× excitation current

0.5 μA shutdown current

Low input bias current: 100 pA

High CMRR: 120 dB

Space savings: 16-lead, 3.0 mm × 3.0 mm × 0.55 mm LFCSP

Excitation current

The AD8290 contains both an adjustable current source to

drive a sensor and a difference amplifier to amplify the signal

voltage. The amplifier is set for a fixed gain of 50. The AD8290

is an excellent solution for both the drive and the sensing aspects

required for pressure, temperature, and strain gage bridges.

In addition, because the AD8290 operates with low power,

works with a range of low supply voltages, and is available in a

low profile package, it is suitable for drive/sense circuits in

portable electronics as well.

300 μA to 1300 μA range

Set with external resistor

The AD8290 is available in a lead free 3.0 mm × 3.0 mm ×

0.55 mm package and is operational over the industrial

temperature range of −40°C to +85°C.
