What are the key features of TS1854IDT?
- 90 dB typical CMRR enabling precise differential signal amplification with superior noise rejection
- Ultra-low 0.055 µA average bias current minimizing loading errors on high-impedance sensor sources
- Quad op-amp integration in a 14-pin SO package reducing component count versus 4 discrete single-channel amplifiers
What is TS1854IDT used for?
The TS1854IDT is suited for precision analog signal conditioning in industrial sensor interfaces, audio processing circuits, and data acquisition front-ends requiring multiple amplification stages. Its 90 dB common-mode rejection ratio makes it effective for instrumentation amplifier topologies measuring small differential signals in the presence of large common-mode noise from 50 Hz or 60 Hz power lines. Medical measurement equipment and battery management analog front-ends benefit from its low bias current that preserves measurement accuracy when interfacing high-source-impedance transducers.

Frequently Asked Questions
What common-mode rejection ratio does TS1854IDT achieve and why is 90 dB CMRR significant for sensor interfaces?
The TS1854IDT achieves a typical CMRR of 90 dB with a minimum guaranteed value of 60 dB, which means common-mode noise signals are attenuated by a factor of 31,623 relative to differential signals. This 90 dB rejection level is critical for rejecting 50 Hz or 60 Hz mains interference on thermocouple or bridge sensor inputs where differential voltages can be as small as 1 mV against hundreds of millivolts of common-mode noise.
How does the 0.063 µA maximum bias current of TS1854IDT affect the accuracy of high-impedance sensor measurements?
With a maximum input bias current of 0.063 µA at 25°C, the TS1854IDT introduces a worst-case offset voltage of only 63 µV when driving a 1 MΩ source impedance sensor, compared to 630 µV with a 10x higher bias current amplifier. This low bias current characteristic preserves measurement accuracy for pH probes, photodiodes, and piezoelectric sensors with source impedances ranging from 100 kΩ to 10 MΩ.
How many independent amplifier channels does TS1854IDT integrate and what board space does it save?
The TS1854IDT integrates 4 independent operational amplifier channels within a single 14-pin SO package occupying approximately 8.65 mm x 3.9 mm of PCB area. Using one TS1854IDT replaces 4 separate single-channel op-amps, reducing the total footprint by up to 60% compared to 4 individual SOT-23-5 packages while also cutting soldering points from 20 down to 14.
What is the factory lead time for TS1854IDT and how should supply chain teams plan for high-volume orders?
The TS1854IDT carries a factory lead time of 20 weeks, making early procurement planning essential for production programs. Supply chain teams should place blanket purchase orders at least 5 months before first production, and maintaining a 4-week safety stock buffer covering peak demand periods minimizes the risk of line stoppages caused by lead time variability in the 14-pin SO package supply chain.
