DESCRIPTION

The INA126 and INA2126 are precision instrumentation amplifiers
for accurate, low noise differential signal acquisition. Their
two-op-amp design provides excellent performance with very
low quiescent current (175μA/channel). This, combined with a
wide operating voltage range of ±1.35V to ±18V, makes them
ideal for portable instrumentation and data acquisition systems.
Gain can be set from 5V/V to 10000V/V with a single
external resistor. Laser trimmed input circuitry provides low
offset voltage (250μV 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 finepitch
surface mount, SO-16, and 16-pin DIP. All are specified
for the –40°C to +85°C industrial temperature range.
