POWER INSTRUMENTATION AMPLIFIER

Single and Dual Versions

DESCRIPTION

The INA126 and INA2126 are precision instrumentation ampli-

fiers for accurate, low noise differential signal acquisition. Their

two-op-amp design provides excellent performance with very

low quiescent current (175

µA/channel). This, combined with a

wide operating voltage range of

±1.35V to ±18V, makes them

ideal for portable instrumentation and data acquisition sys-

tems.

Gain can be set from 5V/V to 10000V/V with a single

external resistor. Laser trimmed input circuitry provides low

offset voltage (250

µV max), low offset voltage drift (3µV/°C

max) and excellent common-mode rejection.

Single version package options include 8-pin plastic DIP,

SO-8 surface mount, and fine-pitch MSOP-8 surface-mount.

Dual version is available in the space-saving SSOP-16 fine-

pitch surface mount, SO-16, and 16-pin DIP. All are specified

for the –40

°C to +85°C industrial temperature range.

APPLICATIONS

q INDUSTRIAL SENSOR AMPLIFIER:

Bridge, RTD, Thermocouple

q PHYSIOLOGICAL AMPLIFIER:

ECG, EEG, EMG

q MULTI-CHANNEL DATA ACQUISITION

q PORTABLE, BATTERY OPERATED SYSTEMS
