What are the key features of TLC27L4BCDRG4?
- Quad CMOS op-amp with 0.0006 µA ultra-low bias current for high-impedance signal processing
- 94 dB typical CMRR with 5 V to 15 V supply range enabling versatile single and dual-supply designs
- Four amplifiers in 14-pin SOIC reducing board area and component count for multi-channel filtering
What is TLC27L4BCDRG4 used for?
The TLC27L4B quad CMOS op-amp is suited for low-frequency precision instrumentation, active anti-aliasing filters, and battery-powered sensor signal conditioning where its 0.085 MHz bandwidth and 0.0006 µA bias current minimize power consumption and measurement error. Its 5 V to 15 V supply compatibility and four channels in a single 14-pin SOIC make it efficient for multi-channel data acquisition front-ends and pH meter circuits.

Frequently Asked Questions
What makes TLC27L4BCDRG4 suitable for low-frequency precision signal conditioning versus wideband op-amps?
The TLC27L4B's 0.085 MHz bandwidth with 0.0006 µA input bias current and 94 dB CMRR optimizes it for DC to audio-range precision filtering where wideband op-amps introduce unnecessary noise. The 4-channel 14-pin SOIC integrates complete quad amplifier chains for sensor conditioning, active low-pass filters, and 5 V to 15 V supply analog front-ends.
How does the 0.0006 µA bias current of TLC27L4BCDRG4 benefit photodiode and electrochemical sensor designs?
With only 0.0006 µA maximum bias current, the TLC27L4B introduces less than 0.6 mV offset error across a 1 GΩ source impedance, making it ideal for transimpedance amplifiers in photodiode current-to-voltage conversion and electrochemical sensors. The 4 channels in 14-pin SOIC allow compact multi-electrode sensor arrays on a single PCB.
When should a designer choose TLC27L4BCDRG4 over a dual op-amp for a 4-channel filter bank?
Using TLC27L4BCDRG4 integrates all 4 filter channels into one 14-pin SOIC, halving the IC count and PCB footprint compared to two dual op-amp packages. At 5 V to 15 V operation with 94 dB CMRR and 0.085 MHz bandwidth, it suits audio filter banks, 4-channel sensor front-ends, and low-power instrumentation where board space and supply current below 1 mA per channel are priorities.
