What are the key features of TS1854IPT?
- 90 dB typical common-mode rejection ratio (CMRR) with 60 dB minimum ensures accurate differential signal amplification in noisy environments
- Low input bias current of 0.063 uA maximum at 25°C reduces errors in high-impedance sensor interface circuits
- Voltage-feedback architecture with internal frequency compensation enables stable closed-loop gain without external capacitors
- Quad op-amp in compact 14-pin TSSOP package saves board space in multi-channel analog front-end designs
What is TS1854IPT used for?
The TS1854IPT is well-suited for precision analog signal conditioning in industrial sensors, data acquisition systems, and instrumentation amplifier circuits requiring low offset and high CMRR. Its four amplifier channels in a single 14-pin TSSOP package make it practical for multi-channel audio mixing, strain-gauge bridge amplification, and medical monitoring front ends. The RoHS-compliant construction supports green manufacturing mandates across consumer and industrial electronics.

Frequently Asked Questions
What is the common-mode rejection ratio of the TS1854IPT, and why does it matter for differential sensor measurements?
The TS1854IPT provides a typical CMRR of 90 dB and a guaranteed minimum of 60 dB. In practice, a 90 dB CMRR means the device attenuates common-mode noise by a factor of 31,623:1, allowing accurate differential voltage readings from strain-gauge bridges or thermocouples even in environments with 50 Hz or 60 Hz interference up to several hundred millivolts.
How does the TS1854IPT's input offset voltage affect precision in a 12-bit ADC measurement chain?
With a maximum input offset voltage of 3000 µV (3 mV), the TS1854IPT introduces a DC error of up to 3 mV at the ADC input. For a 12-bit ADC with a 3.3V reference, one LSB equals 0.8 mV, so the offset is equivalent to roughly 3-4 LSBs. Designs requiring sub-LSB accuracy should add offset trimming or use a lower-offset variant.
Can the TS1854IPT replace LM324 in an existing 4-channel industrial signal conditioning board?
Yes, the TS1854IPT is a pin-compatible quad op-amp in the same 14-pin TSSOP footprint as modern LM324 variants. It offers superior 90 dB CMRR compared to LM324's typical 70 dB, and the 0.063 µA bias current is lower than LM324's 45 nA to 250 nA range depending on supply. The RoHS-compliant e3 JEDEC coding confirms lead-free construction for industrial certifications.
What supply voltage range does the TS1854IPT support for single-supply 5V industrial sensor designs?
The TS1854IPT operates on a single supply from 3V to 16V or a dual supply from ±1.5V to ±8V, covering standard 3.3V, 5V, and 12V industrial rails. At 5V single supply, all 4 amplifiers are active simultaneously with a quiescent current of approximately 1 mA per amplifier, totaling 4 mA for the quad package, which fits within typical low-power sensor node power budgets.
