What are the key features of TS274IDT?
- Ultra-low 0.3 pA input bias current enabling high-impedance sensor interfaces without signal loading errors
- 80 dB typical common-mode rejection ratio with internal frequency compensation for stable precision signal conditioning
- Quad op-amp in 14-pin SOIC package reducing BOM cost and board space versus four discrete single amplifiers
What is TS274IDT used for?
The TS274IDT is designed for precision signal conditioning in industrial sensors, data acquisition front ends, and battery-operated instrumentation where its 0.3 pA input bias current and 80 dB CMRR minimize measurement errors. The quad configuration makes it ideal for active filter chains, summing amplifiers, and multi-channel audio processing where four identical channels must be matched. Its CMOS architecture supports single-supply operation down to low rail voltages, fitting portable medical devices and remote sensing nodes.

Frequently Asked Questions
How does the 0.3 pA input bias current of TS274IDT benefit high-impedance sensor interface designs?
At only 0.3 pA maximum input bias current, the TS274IDT introduces negligible voltage error even with source impedances exceeding 10 MΩ. For a 100 MΩ photodiode transimpedance circuit, the offset voltage contributed by bias current is just 0.03 µV, keeping measurement uncertainty well below the 12 mV input offset voltage spec. This makes the device suitable for pH probes, electrometer inputs, and capacitive touch sensing applications.
What common-mode rejection ratio does the TS274IDT provide, and why does that matter for differential signal acquisition?
The TS274IDT achieves a minimum 65 dB and typical 80 dB common-mode rejection ratio, which means a 1 V common-mode noise signal (such as 50 Hz mains coupling) is attenuated to less than 100 µV at the differential output. In industrial 4-20 mA current loop receivers operating over long cable runs, this level of CMRR suppresses ground-loop interference without external shielding, simplifying system design.
When is the TS274IDT a practical alternative to four separate single op-amps in a multi-channel filter design?
In a 4-channel active Sallen-Key filter stage, replacing four individual amplifiers with a single TS274IDT in a 14-pin SOIC package reduces the PCB footprint by approximately 60 % and cuts placement time from 4 components to 1. All four amplifiers share identical electrical characteristics from the same silicon die, improving channel-to-channel gain matching to better than 0.1 dB without trimming. The result is lower BOM cost and reduced assembly rejects versus sourcing four separate devices.
