Key Features
- Ultra-low 60 pA typical input bias current at 25°C enabling precision measurement of high-impedance electrochemical and photodiode sources
- 94 dB typical common-mode rejection ratio (CMRR) with 60 dB minimum ensuring accurate differential signal amplification in noisy environments
- Dual op-amp with internal frequency compensation in a through-hole DIP package for easy prototyping and manual PCB assembly
Applications
TLC27L2BCP is designed for precision analog circuits requiring extremely low input leakage current, such as pH meter front-ends, ion-selective electrode amplifiers, and photodiode transimpedance stages. Its 94 dB CMRR and 0.06 nA bias current make it well suited for instrumentation amplifier input stages and bridge sensor signal conditioners in scientific and medical equipment. The through-hole DIP package supports breadboard prototyping and retrofit into legacy industrial measurement instruments.

Frequently Asked Questions
What is the input bias current of TLC27L2BCP and why does it matter for sensor interfaces?
TLC27L2BCP has a typical input bias current of only 60 pA at 25°C with a maximum of 0.6 nA, producing negligible voltage error across high-impedance sources such as pH electrodes and photodiodes in precision measurement front-end circuits.
What CMRR does TLC27L2BCP achieve and how does it benefit differential measurement circuits?
TLC27L2BCP achieves 94 dB typical and 60 dB minimum CMRR, effectively rejecting power-line noise and ground loop interference in bridge sensor amplifiers and differential instrumentation circuits used in industrial and medical measurement systems.
For a legacy industrial instrument repair, why is TLC27L2BCP in a DIP package preferable to a modern SMD alternative?
TLC27L2BCP in a through-hole DIP package allows direct board insertion without SMD rework equipment, preserving the 60 pA bias current and 94 dB CMRR performance in legacy instruments where through-hole pads are already present and SMD footprint areas are unavailable.
