What are the key features of TLC27L2CPE4?
- Dual op-amp in a single 8-pin DIP package provides two independent precision voltage-feedback amplifiers with frequency compensation for single-supply systems
- Ultra-low bias current maximum of 0.0006 µA enables accurate signal conditioning of high-impedance sensor sources without loading errors
- 60 dB minimum common-mode rejection ratio (CMRR) with 94 dB typical ensures precise rejection of common-mode noise in differential measurement circuits
- Single-supply micropower design reduces quiescent current consumption, extending battery life in portable and energy-harvesting applications
What is TLC27L2CPE4 used for?
The TLC27L2CPE4 is used in precision sensor signal conditioning, battery-powered data loggers, and single-supply instrumentation amplifier front ends where dual-channel ultra-low bias current and 94 dB typical CMRR are required. Its 8-pin DIP package suits prototyping and through-hole production boards for medical biosignal monitors, industrial 4-20 mA transmitters, and pH or temperature measurement instruments operating from a single 5 V supply.

Frequently Asked Questions
What is the maximum input bias current and CMRR specification of TLC27L2CPE4?
The TLC27L2CPE4 has a maximum average input bias current of 0.0006 µA and a minimum common-mode rejection ratio of 60 dB, with a typical CMRR of 94 dB, enabling precise low-noise signal amplification from high-impedance sources in single-supply measurement systems.
How does the micropower single-supply design of TLC27L2CPE4 benefit battery-operated instruments?
The micropower architecture of TLC27L2CPE4 minimizes quiescent current draw to the µA range, allowing portable instruments to run for months on a single-cell battery while maintaining precision amplification with 0.0006 µA bias current and 10 mV maximum input offset voltage across both channels.
In which sensor interface circuits is TLC27L2CPE4 preferred over standard op-amps with higher bias currents?
TLC27L2CPE4 is preferred for pH sensors, piezoelectric transducers, and photodiode front ends where source impedances exceed 100 MΩ, as its 0.0006 µA maximum bias current causes less than 60 µV of offset error at 100 MΩ, far superior to standard op-amps with 100 nA bias currents that would introduce 10 V of error.
What does the 8-pin DIP package of TLC27L2CPE4 offer for prototyping and low-volume production?
The 8-pin DIP (dual-in-line) package allows direct insertion into breadboards and DIP sockets, enabling rapid prototyping of dual-channel precision amplifier circuits without soldering, and supports through-hole PCB production where wave soldering assembly is preferred for low-volume or ruggedized industrial instruments.
