What are the key features of LTC2067IMS8#PBF?
- Zero-drift architecture eliminates DC offset and 1/f noise, achieving sub-µV offset voltage stability over temperature for precision measurement
- Ultra-low 10 µA total supply current enabling long-duration battery-powered sensor applications with minimal power budget impact
- 35 fA maximum input bias current at 25°C supporting high-impedance transducer interfaces such as pH electrodes and photodiodes without signal loading errors
- 123 dB typical CMRR and 103 dB minimum CMRR ensuring excellent rejection of common-mode noise in differential measurement front ends
What is LTC2067IMS8#PBF used for?
The LTC2067IMS8#PBF is used in precision medical instrumentation, portable gas analyzers, and electrochemical sensor interfaces where the 35 fA input bias current prevents signal loading errors from high-impedance transducers such as pH electrodes or ion-selective sensors. Its zero-drift topology and 10 µA supply current per amplifier make it ideal for battery-operated data acquisition front ends, wearable biosensors, and long-life IoT sensor nodes that must maintain sub-µV accuracy over extended temperature ranges. The dual-channel MSOP-8 package enables compact two-channel differential amplifier stages in handheld instruments where board space is strictly limited.

Frequently Asked Questions
How does the LTC2067IMS8#PBF's zero-drift architecture benefit long-term DC accuracy in a precision temperature measurement circuit?
The zero-drift (auto-zero chopper) architecture of the LTC2067IMS8#PBF continuously corrects input offset voltage, achieving offset drift below 50 nV/°C over the -40°C to 125°C operating range. In a Wheatstone bridge temperature sensor interface running from a 5 V supply, this translates to less than 5 µV total offset error over 100°C of temperature change, enabling millikelvin-resolution measurements without the trimming and recalibration requirements typical of standard bipolar op-amps with offset drift of 1 µV/°C to 10 µV/°C.
In which high-impedance transducer applications does the 35 fA bias current of the LTC2067IMS8#PBF provide a meaningful accuracy advantage?
For a pH electrode with 100 MΩ source impedance, a conventional op-amp with 1 nA bias current creates a 100 mV input error — equivalent to nearly 1.7 pH units — while the LTC2067IMS8#PBF's 35 fA bias current produces only 3.5 µV of input error, eliminating the dominant error source in electrochemical measurement. Similarly, in photodiode transimpedance amplifiers with 1 GΩ feedback resistors, the 35 fA bias current contributes only 35 µV of output offset, enabling sub-nanoampere photocurrent measurements in optical instruments and fluorescence sensors.
How does the LTC2067's 10 µA supply current compare to standard precision op-amps, and what battery life improvement does this enable?
The LTC2067IMS8#PBF draws only 10 µA total supply current for both amplifier channels combined, compared to 500 µA to 1 mA for standard precision op-amps such as the OPA2188. In a battery-powered sensor node with a 100 mAh coin cell (CR2032), replacing a 1 mA op-amp with the LTC2067 reduces the amplifier's contribution to battery drain from 1 mA to 0.005 mA, extending battery life from approximately 100 hours to over 20,000 hours of continuous operation, a factor of 200 improvement attributable solely to the op-amp selection.
When would a designer select LTC2067IMS8#PBF over LTC2064 single-channel op-amp for a two-channel measurement front end?
The LTC2067IMS8#PBF integrates two matched zero-drift op-amp channels in a single 8-pin MSOP package measuring approximately 5.0 mm × 3.2 mm, whereas implementing two LTC2064 channels requires two separate SOT-23-5 packages consuming nearly twice the PCB area. When both channels share the same supply rail and the application benefits from matched offset temperature characteristics across channels (for differential measurements), the LTC2067 also provides better channel-to-channel tracking, achieving less than 100 nV of differential channel offset mismatch across temperature, which reduces common-mode errors in bridge and differential ADC front-end designs.
