What are the key features of TLC084IDRG4?
- Quad voltage-feedback op-amp with 80 dB minimum CMRR (110 dB typical) for superior noise rejection in precision measurement front-ends
- Ultra-low bias current of 0.7 nA maximum and 50 pA typical at 25°C, minimizing errors in high-impedance sensor amplifier stages
- 1.9 mV maximum input offset voltage with internal frequency compensation simplifies stable gain designs without external capacitors
What is TLC084IDRG4 used for?
TLC084IDRG4 is used in precision signal conditioning, active filter design, and instrumentation amplifier circuits where four op-amp stages are needed in a single small-outline package. Its low bias current and high CMRR make it suitable for medical diagnostic equipment, industrial weigh cells, and pH sensor signal chains. The device also fits audio mixing consoles and analog processing boards that require four matched, low-noise amplifier channels with minimal offset drift.

Frequently Asked Questions
What is the common-mode rejection ratio specification for TLC084IDRG4?
TLC084IDRG4 achieves a minimum CMRR of 80 dB and a typical CMRR of 110 dB. This high rejection level attenuates common-mode noise on both input pins by a factor of more than 100,000 times, making it reliable in electrically noisy industrial environments where ground-referenced differential signals must be amplified accurately.
How does the bias current of TLC084IDRG4 affect high-impedance sensor interface designs?
TLC084IDRG4 has a maximum bias current of 0.7 nA and a typical value of 50 pA at 25°C. At a source impedance of 1 MΩ, even the maximum 0.7 nA bias produces only 0.7 mV of additional offset error, which is acceptable for most pH electrode, photodiode, or humidity sensor front-ends without requiring compensation resistors.
For a 4-channel active filter board, what does TLC084IDRG4 offer versus using four single op-amps?
TLC084IDRG4 integrates 4 matched voltage-feedback op-amps in a single SOIC package, reducing the component count from 4 chips to 1. This cuts board area by roughly 75% and improves channel-to-channel matching of input offset voltage below 1.9 mV, which matters in precision differential filters and instrumentation amplifier designs requiring consistent gain across channels.
Does TLC084IDRG4 require external frequency compensation capacitors?
No, TLC084IDRG4 has internal frequency compensation, so no external capacitors are needed to ensure stable operation at any closed-loop gain from unity upward. This simplifies the PCB layout, eliminates the risk of incorrect compensation network values, and reduces the passive component count by at least 4 capacitors versus uncompensated op-amp designs.
