3 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 low
quiescent current (175 μA/channel). Combined with a
wide operating voltage range of ±1.35 V to ±18 V,
makes the INAx126 ideal for portable instrumentation
and data acquisition systems.
Gain can be set from 5 V/V to 10000 V/V with a
single external resistor. Laser-trimmed input circuitry
provides low offset voltage (250-μV maximum), low
offset voltage drift (3-μV/°C maximum), and excellent
common-mode rejection.
Single version package options include 8-pin plastic
PDIP, SOIC-8, and fine-pitch VSSOP-8 surface-
mount. Dual version is available in 16-pin plastic
PDIP, SOIC-8, and the space-saving, fine-pitch
SSOP-16 surface-mount. All are specified for the
–40°C to +85°C industrial temperature range.
