What are the key features of TS942ID?
- Dual rail-to-rail input and output (RRIO) capability enabling full supply-range signal swing in single-supply systems
- Ultra-low bias current of 0.15 nA max minimizing loading errors in high-impedance sensor measurement circuits
- 85 dB typical common-mode rejection ratio (CMRR) for excellent noise immunity in differential signal paths
- SOIC-8 package with voltage-feedback architecture compatible with standard op-amp footprints and layout practices
What is TS942ID used for?
The TS942ID is well-suited for battery-powered instrumentation, precision sensor signal conditioning, and active filter stages where rail-to-rail output swing is essential to maximize dynamic range from a single 3.3 V or 5 V supply. Its dual-channel configuration in one SOIC-8 package simplifies BOM and board space for two-channel amplifier stages such as differential line receivers and Wheatstone bridge amplifiers. The low bias current of 0.15 nA makes it an excellent match for pH electrode amplifiers, photodiode transimpedance stages, and other high-impedance sensor interfaces.

Frequently Asked Questions
How low is the input bias current of the TS942ID and why does that matter for sensor interfaces?
The TS942ID has a maximum input bias current of 0.15 nA (0.00015 µA) at 25°C. This extremely low value prevents loading errors on high-impedance sources such as pH electrodes and piezoelectric sensors, where even a few nanoamps of leakage could shift the measured voltage by millivolts, degrading 12-bit or 16-bit ADC accuracy.
For a single 3.3 V supply design, how far can the TS942ID output swing relative to the supply rails?
The TS942ID features a rail-to-rail output stage that swings to within a few millivolts of both the positive and negative supply rails. On a 3.3 V single supply, this means the output can cover nearly the full 3.3 V range, maximizing the dynamic range presented to an ADC and avoiding wasted headroom that a conventional op-amp would lose at each rail.
What is the common-mode rejection ratio of the TS942ID and which circuit topologies rely on it?
The TS942ID achieves a typical CMRR of 85 dB and a minimum of 60 dB. Differential amplifier and instrumentation front-end topologies depend on high CMRR to reject common-mode interference such as 50 Hz or 60 Hz power-line noise. With 85 dB rejection, the device attenuates a 1 V common-mode signal to less than 6 µV at the differential output.
How does packaging two amplifiers in one SOIC-8 compare to using two single op-amp SOT-23 devices?
The dual SOIC-8 TS942ID occupies approximately the same board footprint as a single SOT-23 op-amp (roughly 19 mm² vs 9 mm² per channel), yet it replaces two separate single-channel parts, cutting component count in half. This reduces BOM line items, placement time, and the risk of mismatch between two separately sourced single-channel amplifiers in matched-gain applications.
