Key Features
- 90 µV maximum input offset voltage with 100 dB typical CMRR enables high-accuracy signal conditioning without external trimming
- Ultra-low 300 µA total supply current for both channels enables always-on precision amplification in battery-powered instruments
- 2.7 V to 12 V single-supply or dual ±1.35 V to ±6 V operation in compact 8-pin MSOP package covers wide range of analog circuit topologies
Applications
LTC6081IMS8#PBF is suited for precision instrumentation front-ends such as thermocouple amplifiers, load cell signal conditioners, and 16-bit ADC input buffers where low offset and high CMRR are critical. Its ultra-low 300 µA supply current makes it practical for always-on monitoring circuits in portable medical equipment and field instruments running from batteries or energy-harvesting sources. The dual channel in the MSOP-8 package enables compact differential amplifier and active filter implementations with minimal board area.

Frequently Asked Questions
How does LTC6081IMS8#PBF's 90 µV offset compare to a standard CMOS op-amp, and does it need external offset trimming?
A standard general-purpose CMOS op-amp often specifies 1 mV to 5 mV maximum offset, whereas LTC6081IMS8#PBF guarantees a maximum of 90 µV across the industrial temperature range. This 10x to 50x improvement eliminates the need for an external offset trimming resistor network in most precision applications, simplifying BOM and ensuring stable accuracy over time and temperature without periodic re-calibration.
What CMRR does LTC6081IMS8#PBF guarantee, and how does it benefit a differential sensor measurement circuit?
LTC6081IMS8#PBF guarantees a minimum CMRR of 88 dB with a typical value of 100 dB. In a differential measurement circuit such as a bridge amplifier or RTD conditioner, 88 dB CMRR means common-mode noise of 1 V on both inputs appears as only 40 µV of error at the output, making it suitable for industrial environments with significant ground noise up to several hundred millivolts.
For a portable data logger running from a 3.3 V single supply, how much power does LTC6081IMS8#PBF consume and can it run continuously from a coin cell?
LTC6081IMS8#PBF draws only 300 µA total supply current for both amplifier channels at 3.3 V, consuming approximately 1 mW. A CR2032 coin cell rated at 220 mAh can theoretically power the device alone for over 730 hours of continuous operation. In a data logger application with duty-cycled MCU and sensor activity, the op-amp's always-on bias is rarely the limiting factor for battery life.
