Applications
The LT1672IMS8#PBF suits precision battery-powered instrumentation and portable medical devices where 2 µA quiescent current extends runtime while rail-to-rail I/O maximizes the usable signal range on a single-supply rail. It is used in sensor signal conditioning circuits, portable data loggers, and low-power analog front-ends where the 96 dB minimum CMRR rejects interference on differential sensor lines. High-impedance bridge and electrochemical sensor interfaces also benefit from its 0.001 µA bias current, which prevents measurement errors caused by current loading of sensitive source impedances.

Frequently Asked Questions
What makes the LT1672IMS8#PBF suitable for battery-powered sensor measurement circuits?
The LT1672IMS8#PBF draws only 2 µA of supply current and provides rail-to-rail input and output, which together extend battery life while maximizing the measurable signal range on low-voltage single-supply rails common in portable sensors and data loggers.
How does the 96 dB minimum CMRR of the LT1672IMS8#PBF benefit differential sensor signal conditioning?
A 96 dB minimum common-mode rejection ratio means the LT1672IMS8#PBF attenuates common-mode interference by a factor of over 63,000, effectively eliminating 50 Hz or 60 Hz power-line noise and ground potential differences from differential sensor outputs, preserving measurement accuracy in industrial environments.
Why is the 0.001 µA bias current of the LT1672IMS8#PBF important when amplifying signals from high-impedance electrochemical sensors?
With a bias current of only 0.001 µA at 25°C, the LT1672IMS8#PBF introduces less than 0.001 µA of current into a high-impedance source, meaning even a 10 MOhm electrode impedance produces a negligible 10 µV of input error, preserving measurement accuracy in pH, biosensor, and ion-selective electrode applications.
