Texas Instruments Low Power Instrumentation Amplifier, 800kHz

This Texas Instruments Low Power Instrumentation Amplifier offers excellent accuracy and versatility through its 3-op amp design. Its compact size makes it ideal for a wide range of applications, including portable and battery-operated systems.

The current-feedback input circuitry provides a wide bandwidth even at high gain, delivering 70kHz at G=100. Gain can be easily configured from 1 to 10,000 using a single external resistor. The amplifier features internal input protection that can withstand up to ±40V without damage.

Precision is ensured through laser trimming, achieving very low offset voltage and drift, alongside a high common-mode rejection of 110dB at G=1000. It operates on power supplies as low as ±1.35V and features a low quiescent current of just 350µA, making it highly suitable for battery-operated systems.
