Frequently Asked Questions
What input offset voltage does the LT1125CN#PBF guarantee, and how does that affect precision measurement designs?
The LT1125CN#PBF guarantees a maximum input offset voltage of 210 µV, which ensures minimal DC error in precision measurement circuits. This low offset allows accurate signal conditioning in bridge sensors and strain gauge amplifiers operating at millivolt-level signals without significant calibration overhead.
How many independent amplifier channels does the LT1125CN#PBF provide, and what supply voltage range does it support?
The LT1125CN#PBF integrates 4 independent op-amp channels in a single 14-pin DIP package. Its voltage-feedback architecture and frequency compensation enable stable operation across a range of supply voltages, making it suitable for multi-channel instrumentation systems requiring matched performance across all 4 channels.
In what applications is the LT1125CN#PBF a strong alternative to discrete op-amp solutions?
The LT1125CN#PBF is an excellent alternative to discrete solutions in audio preamp stages, thermocouple amplifiers, and multi-channel data acquisition front ends. Its 122 dB typical CMRR and 45 nA bias current max reduce component count while maintaining precision performance across -40°C to +85°C operating temperature range.
