What are the key features of TS974IN?
- Quad rail-to-rail output op-amp architecture enabling signal swing to within millivolts of both supply rails in single-supply systems
- Very low noise voltage density suitable for sensitive audio, instrumentation, and sensor signal conditioning chains
- 60 dB minimum / 85 dB typical Common-Mode Rejection Ratio (CMRR) for excellent rejection of noise on power supply lines
- 14-pin DIP package (R-PDIP-T14) allowing easy prototyping on breadboards and through-hole PCB designs
What is TS974IN used for?
The TS974IN is well suited for precision analog front-end circuits requiring low noise amplification of sensor outputs, such as pressure transducers, strain gauges, and temperature sensors in industrial measurement equipment. Its rail-to-rail output swing is advantageous in single-supply 5 V or 3.3 V systems where maximum dynamic range from a quad amplifier is needed, including audio filtering and active anti-aliasing filter stages. Engineers also use it in portable medical devices and data acquisition systems where four independent amplifier channels in one 14-pin DIP package reduce component count.

Frequently Asked Questions
What CMRR does the TS974IN achieve, and why does it matter for sensor amplification?
The TS974IN achieves a minimum Common-Mode Rejection Ratio (CMRR) of 60 dB and a typical CMRR of 85 dB, which is critical when amplifying small differential signals from sensors like thermocouples or bridge transducers in the presence of common-mode noise. A higher CMRR ensures that power supply noise and electromagnetic interference appearing equally on both inputs is attenuated by at least 60 dB relative to the desired differential signal.
For a 5 V single-supply design, how close to the rails does the TS974IN output swing?
The TS974IN's rail-to-rail output stage swings to within approximately 50 mV to 100 mV of each supply rail in a 5 V single-supply configuration, delivering an effective output voltage range of roughly 0.05 V to 4.95 V. This maximizes the usable dynamic range for analog-to-digital converter (ADC) input stages and active filters, avoiding the signal clipping that would occur with conventional op-amps limited to mid-rail output swings.
How does the 14-pin DIP package of the TS974IN simplify prototyping compared to surface mount quad op-amps?
The TS974IN's 14-pin DIP (R-PDIP-T14) package with 2.54 mm lead pitch inserts directly into standard breadboards and prototype sockets, allowing engineers to build and test quad-channel amplifier circuits without soldering. This is a significant advantage during early design iteration compared to SOIC or TSSOP surface mount packages that require adapter boards or reflow soldering, reducing prototype turnaround time by hours per design cycle.
What is the maximum input offset voltage of the TS974IN, and which designs are most sensitive to this parameter?
The TS974IN specifies a maximum input offset voltage of 7000 µV (7 mV) at 25°C. This level of offset is acceptable for audio signal processing and general-purpose filtering but may introduce DC errors in precision instrumentation or high-gain sensor amplification circuits. For gain settings above 100 V/V, a 7 mV offset translates to 700 mV of output error, so designs requiring sub-millivolt accuracy should consider autozero or chopper-stabilized alternatives.
