Key Features
- Rail-to-rail output swing on all 4 amplifier channels maximizes dynamic range in single-supply 5 V or 3.3 V signal conditioning circuits
- Ultra-low 0.8 nA maximum bias current enables accurate signal processing with high-impedance sensors such as photodiodes or pH probes
- 80 dB typical CMRR with internal frequency compensation simplifies stable filter and instrumentation amplifier designs without external compensation networks
Applications
The TLC2274AIDG4 is widely used in sensor signal conditioning, active filter stages, and data acquisition front ends where four op-amp channels are needed in a single compact SOIC-14 footprint. Its rail-to-rail output and low bias current make it well suited for battery-powered portable instruments and single-supply 5 V embedded systems interfacing with resistive or capacitive sensors. The quad configuration reduces board space and BOM count compared to four single-channel op-amps in precision measurement and control designs.

Frequently Asked Questions
How does the TLC2274AIDG4 rail-to-rail output benefit single-supply 3.3 V or 5 V designs?
The rail-to-rail output of the TLC2274AIDG4 allows each amplifier to swing within millivolts of both supply rails, maximizing the usable output voltage range to nearly the full supply. In a 3.3 V system, this means an effective dynamic range approaching 3.3 V instead of the reduced 1.5 V to 1.8 V swing typical of non-rail-to-rail op-amps, which improves ADC resolution in data acquisition stages.
What is the bias current of the TLC2274AIDG4 and why does it matter for high-impedance sensor interfaces?
The TLC2274AIDG4 specifies a maximum bias current of 0.8 nA and a typical value of 60 fA at 25°C. This near-zero bias current prevents significant voltage error at the input when used with high-impedance sources such as pH electrodes, photodiodes, or piezoresistive sensors where a 1 MΩ source impedance combined with even 100 nA of bias would produce 100 mV of offset error.
How many op-amp channels does the TLC2274AIDG4 integrate and what supply voltage range does it support?
The TLC2274AIDG4 integrates 4 independent operational amplifiers in a single 14-pin SOIC package. It operates from a dual supply of ±8 V or a single supply of up to 16 V, covering both split-rail industrial signal chains and single-supply embedded systems. All 4 channels share a common CMRR specification of 75 dB minimum and 80 dB typical.
