Key Features
- Over-the-top input operation allowing common-mode voltages to exceed the positive supply rail by up to 44 V for high-side current sensing
- Rail-to-rail input and output (R2R) swing enabling signal processing close to both supply rails in single or dual supply configurations
- 103 dB typical common-mode rejection ratio (CMRR) with 86 dB minimum, ensuring high precision in noisy industrial environments
- Micropower quiescent current of only 45 µA enabling battery-powered and energy-harvesting sensor designs with minimal self-discharge
Applications
The LT1636CMS8#TRPBF is ideal for high-side current sensing in battery management systems where the common-mode voltage exceeds the op-amp supply rail by tens of volts. Its rail-to-rail output and precision 103 dB CMRR make it suitable for precision instrumentation amplifiers, industrial 4–20 mA current loop interfaces, and data acquisition front-ends. The low-quiescent-current design also fits portable medical monitors and remote sensor nodes where power budget is tight.

Frequently Asked Questions
How far above the positive supply rail can the LT1636CMS8#TRPBF common-mode input voltage extend?
The LT1636CMS8#TRPBF supports an over-the-top common-mode input voltage that can exceed the positive supply by up to 44 V, with supply voltages ranging from 2.7 V to 44 V single supply. This makes it suitable for high-side current sensing on 12 V, 24 V, and 48 V industrial power rails without level-shifting circuitry.
What is the CMRR specification of the LT1636CMS8#TRPBF, and why does it matter in a current-sense design?
The LT1636CMS8#TRPBF achieves a typical CMRR of 103 dB with a minimum of 86 dB. In a current-sense application riding on a 48 V bus, 103 dB CMRR limits the common-mode error to under 50 µV referred to input, preserving measurement accuracy even in noisy switch-mode power converter environments.
Which sensor interface designs benefit most from the LT1636CMS8#TRPBF rail-to-rail output?
Designs using 3.3 V or 5 V single-supply ADCs benefit most, since the rail-to-rail output allows the amplified signal to swing within millivolts of both rails, maximizing the ADC input range and effective resolution. For a 12-bit ADC on a 3.3 V supply, this can recover roughly 2 additional bits of dynamic range compared to an op-amp with 300 mV output headroom loss.
How does the LT1636CMS8#TRPBF quiescent current compare to general-purpose op-amps for battery-powered sensing?
The LT1636CMS8#TRPBF draws only 45 µA quiescent current per amplifier, compared to 1–5 mA for many general-purpose op-amps. In a coin-cell powered sensor node running on a 220 mAh CR2032 battery, this difference extends autonomous operation from under 50 hours to over 4800 hours under always-on measurement conditions.
