INA126 – Micro Power Instrumentation Amplifier IC SMD
The INA126 is a precision instrumentation amplifier for accurate, low noise differential-signal acquisition. Its two-op-amp design provides excellent performance with low quiescent current (175 ìA/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. It is specified for the –40°C to +85°C industrial temperature range.
