What are the key features of LT1492CN8#PBF?
- Dual op-amp operating on ±18 V or 36 V single-supply rails with 101 dB typical CMRR for precision signal conditioning
- Ultra-low 0.1 µA bias current at 25°C minimizing offset errors in high-impedance sensor and instrumentation circuits
- 8-pin PDIP package enabling direct breadboard prototyping and easy through-hole PCB assembly for lab and industrial designs
What is LT1492CN8#PBF used for?
The LT1492CN8#PBF is used in precision analog instrumentation circuits such as strain-gauge bridges, thermocouple amplifiers, and pH sensor signal chains where its 101 dB CMRR and 0.1 µA bias current minimize common-mode noise and offset errors. It also serves in audio preamplifier stages and active filter designs that operate from ±15 V or ±18 V bipolar supplies, taking advantage of its wide supply range. The dual-channel configuration in a single 8-pin DIP package reduces component count in two-channel analog front ends for data acquisition systems.

Frequently Asked Questions
What supply voltage range and CMRR does LT1492CN8#PBF support for precision instrumentation?
The LT1492CN8#PBF operates from supplies up to ±18 V or 36 V single-supply and achieves a minimum 84 dB CMRR (101 dB typical), making it suitable for precision instrumentation amplifiers measuring low-level differential signals in the presence of common-mode noise.
For a strain-gauge bridge amplifier running on ±15 V rails, how does the 0.1 µA bias current of LT1492CN8#PBF minimize measurement error?
With only 0.1 µA maximum bias current at 25°C, the LT1492CN8#PBF introduces less than 1 mV of offset voltage when driving a 10 kΩ source resistance, preserving measurement accuracy in strain-gauge and load-cell circuits operating from ±15 V bipolar supplies.
How does the dual-channel configuration of LT1492CN8#PBF benefit a two-channel data acquisition front end?
Integrating 2 op-amp channels in a single 8-pin PDIP package halves the component count compared to two single op-amps, reducing PCB area by approximately 40% and simplifying layout of matched two-channel instrumentation front ends for simultaneous differential voltage measurements.
When should LT1492CN8#PBF be selected over a lower-cost general-purpose op-amp for an active filter design?
LT1492CN8#PBF is preferred when the active filter must operate from supplies as high as ±18 V to maximize dynamic range, needs CMRR above 84 dB to reject power-supply noise, or requires 0.1 µA bias current to avoid output offset errors caused by high-impedance resistors in the filter network.
