What are the key features of TS1872IDT?
- Rail-to-rail input and output swings on a 1.8 V supply enable maximum dynamic range in low-voltage IoT and wearable sensor applications
- 80 dB typical CMRR with 60 dB minimum provides excellent common-mode noise rejection for precision signal conditioning near 1.8 V rails
- Ultra-low supply voltage operation from 1.8 V with 150 nA bias current extends battery life in portable and energy-harvesting designs
What is TS1872IDT used for?
The TS1872IDT is a low-voltage, low-power op-amp optimized for battery-powered and energy-harvesting applications such as wearable health monitors, IoT sensor nodes, and portable medical devices. Its rail-to-rail input and output capability on a 1.8 V supply maximizes the usable signal range, while the 80 dB CMRR supports accurate signal amplification from low-level sensors such as thermocouples and strain gauges. The SOT-23-5 or similar small-outline packaging enables compact PCB integration in miniaturized consumer electronics.

Frequently Asked Questions
Why is rail-to-rail input and output important for TS1872IDT operating at 1.8 V in sensor signal conditioning?
At a 1.8 V supply, a conventional op-amp might only support input common-mode voltages from 0.3 V to 1.5 V, losing 330 mV at each rail. The TS1872IDT's rail-to-rail inputs and outputs cover the full 0 V to 1.8 V range, allowing signal conditioning of sensor outputs that swing within 50 mV of the supply rails and maximizing 12-bit ADC utilization by providing over 1.7 V of usable output swing.
How does the 80 dB CMRR of TS1872IDT compare to standard op-amps and why does it matter in noisy environments?
The TS1872IDT achieves 80 dB typical CMRR, which attenuates common-mode noise by a factor of 10,000x. Standard general-purpose op-amps often specify only 60 to 70 dB CMRR, providing 10x to 30x less rejection. In battery-powered devices near switching power supplies generating 100 mV of common-mode noise, the TS1872IDT reduces this interference to below 10 µV at the output, preserving measurement accuracy in 16-bit sensor chains.
What input offset voltage does TS1872IDT specify, and how should designers compensate for it in precision low-voltage circuits?
The TS1872IDT specifies a maximum input offset voltage of 6000 µV (6 mV). On a 1.8 V supply with unity gain, this represents a 0.33% full-scale error—equivalent to losing more than 1 LSB in a 10-bit ADC system. Designers can reduce this error by using the op-amp in a non-unity gain configuration of at least 10x, which divides the referred input offset to 600 µV, or by calibrating the system offset digitally after production.
For a wearable biosensor design, how does TS1872IDT's 150 nA bias current influence front-end circuit design with high-impedance electrodes?
The TS1872IDT's maximum bias current of 150 nA creates a voltage error of 150 µV across a 1 MΩ electrode impedance, which is significant for biopotential measurements but acceptable for most ECG or EEG front-ends with gain of 100x or more. Using 100 kΩ input resistors instead of 1 MΩ reduces this bias-current error to 15 µV, well within the TS1872IDT's 6 mV offset budget, while still providing adequate signal source buffering in 1.8 V-powered wearables.
