Key Features
- 117 dB typical CMRR with 300 µV max input offset voltage enables ultra-precision differential signal amplification across 4 matched channels
- 0.03 µA max input bias current at 25°C minimizes errors in high-impedance sensor and transducer interface circuits
- Internal frequency compensation in 14-pin DIP package simplifies quad-channel precision amplifier PCB design without external components
Applications
LT1014CNE4 is optimized for precision instrumentation and measurement systems requiring four closely matched amplifier channels with minimal input offset error. Its 117 dB CMRR makes it ideal for Wheatstone bridge sensor interfaces, strain gauge amplifiers, and differential thermocouple measurement circuits. Data acquisition front ends and medical-grade signal conditioning equipment benefit from its low 0.002 µA offset current and guaranteed 97 dB minimum CMRR.

Frequently Asked Questions
What CMRR performance does LT1014CNE4 deliver, and how does it benefit bridge sensor measurement circuits?
LT1014CNE4 achieves 117 dB typical CMRR with a guaranteed minimum of 97 dB, rejecting common-mode interference by a factor of over 200,000 times. In a 5 V Wheatstone bridge application, this level of CMRR reduces noise-induced measurement error to below 1 µV, enabling sub-millivolt strain or pressure readings without additional filtering.
How many op-amp channels does LT1014CNE4 provide, and what is its input offset voltage?
LT1014CNE4 integrates 4 precision op-amp channels in a single 14-pin DIP package, with a maximum input offset voltage of 300 µV per channel. The quad topology reduces board area and component count compared to using four discrete single op-amps in precision measurement instrumentation designs.
What supply voltage range is LT1014CNE4 compatible with for industrial signal conditioning?
LT1014CNE4 operates on dual supplies from ±2 V to ±18 V, covering the standard ±5 V and ±15 V rails common in industrial instrumentation. The wide supply range, combined with 0.038 µA maximum average bias current, supports direct interface to 4–20 mA sensor loops and high-impedance bridge transducers without output loading errors.
When is LT1014CNE4 a practical lower-cost alternative to four separate precision op-amps in a measurement design?
LT1014CNE4 integrates 4 matched channels sharing a 14-pin DIP package, reducing component count from 4 ICs to 1 while cutting PCB area by approximately 60%. Its 300 µV offset voltage matching between channels is tighter than mixing individual parts from different lots, making it the preferred choice for multichannel differential measurement bridges and ADC front ends.
