- 80 dB typical CMRR with 60 dB minimum ensures excellent common-mode noise rejection in sensor amplifier circuits
- Ultra-low bias current of 0.13 µA at 25°C minimizes loading on high-impedance sensor sources
- Voltage-feedback architecture with internal frequency compensation simplifies stable closed-loop filter design
- Low-power consumption enables extended battery life in portable and wearable sensor applications
What is TS1872AIDT used for?
The TS1872AIDT is designed for battery-powered and low-voltage portable applications such as wearable health monitors, handheld measurement instruments, and IoT sensor nodes where a 1.8 V rail-to-rail op-amp with ultra-low 0.13 µA bias current and 80 dB CMRR is needed for accurate signal conditioning. It also serves as a precision amplifier in 1.8 V analog front-ends for medical electrodes, microphone pre-amplifiers, and low-power active filter stages where a 1500 µV maximum offset is acceptable.

Frequently Asked Questions
What supply voltage and input/output swing does TS1872AIDT support for wearable sensor designs?
The TS1872AIDT operates from a 1.8 V supply and provides rail-to-rail input and output swings, meaning the input common-mode range and output voltage both span nearly the full supply range from approximately 0 V to 1.8 V. This maximizes signal dynamic range in wearable sensors and portable devices where headroom is limited by a single lithium-cell supply.
How does the 80 dB CMRR of TS1872AIDT benefit ECG or biomedical signal amplification?
The TS1872AIDT achieves a typical common-mode rejection ratio of 80 dB, with a guaranteed minimum of 60 dB. In ECG and biomedical amplifiers, high CMRR is critical for rejecting 50 Hz or 60 Hz mains interference that appears as a common-mode signal on patient electrodes, ensuring the amplified differential biopotential signal is not masked by power-line noise even at 1.8 V supply.
With a 0.13 µA bias current, how does TS1872AIDT perform when connected to a high-impedance photodiode or pH electrode?
The TS1872AIDT's maximum input bias current of 0.15 µA (0.13 µA typical at 25°C) creates only a small voltage error when driving a high-impedance source such as a photodiode or pH electrode with megaohm source resistance. For a 1 MΩ source, the bias current error is only 0.15 V, which combined with the 1500 µV maximum input offset, keeps total DC error well within acceptable limits for many low-power sensor interfaces.
What is the procurement lead time for TS1872AIDT, and does it affect production planning for high-volume consumer devices?
The TS1872AIDT carries a factory lead time of approximately 20 weeks according to STMicroelectronics data. For high-volume consumer or medical device production, this 20-week lead time means buyers should place orders well in advance or maintain buffer inventory to avoid supply gaps, particularly given the device's specialized 1.8 V rail-to-rail characteristics that make direct substitution less straightforward.
