What are the key features of TLE2142ACD?
- 108 dB typical CMRR for superior rejection of common-mode interference in precision signal paths
- Low 1.5 µA input bias current minimizes errors in high-impedance sensor interfaces and transimpedance stages
- High-speed voltage-feedback architecture with frequency compensation supports wideband precision applications up to several MHz
What is TLE2142ACD used for?
TLE2142ACD is well suited for precision instrumentation amplifiers, active filters, and data acquisition front-ends where both low noise and high accuracy are essential. Its high CMRR and low offset voltage make it a strong choice for strain-gauge bridges, thermocouple signal conditioning, and medical measurement equipment. The dual-channel configuration in a compact SO-8 package supports differential signal processing in space-constrained PCB designs.

Frequently Asked Questions
What CMRR does the TLE2142ACD achieve, and why does that matter for differential sensor measurements?
The TLE2142ACD delivers a typical common-mode rejection ratio of 108 dB, meaning it attenuates common-mode noise by a factor of over 250,000 relative to the differential signal. In a Wheatstone bridge or thermocouple interface running on a noisy industrial PCB, this level of CMRR keeps measurement error below 1 µV even with several hundred millivolts of 50 Hz or 60 Hz interference on the input lines.
How does the 1.5 µA input bias current of TLE2142ACD affect transimpedance amplifier designs?
At 1.5 µA bias current, a 1 MΩ feedback resistor in a transimpedance amplifier introduces a DC offset of 1.5 V, which may require compensation. For photodiode or electrometer circuits demanding less than 100 mV offset error, designers should limit feedback resistance to roughly 50 kΩ or add a matched bias-cancellation resistor at the non-inverting input. Selecting a lower bias-current variant may be preferable for sub-nanoamp signal detection.
What supply voltage range is compatible with TLE2142ACD in mixed-signal board designs?
TLE2142ACD operates from ±5 V to ±15 V dual supply, making it compatible with traditional analog supply rails commonly found in audio, instrumentation, and industrial signal-chain boards. The ±15 V maximum supply provides a large output swing for driving ADC inputs with full-scale ranges up to ±10 V, while the ±5 V minimum allows integration with systems that use a single 10 V or 12 V rail split symmetrically.
When would TLE2142ACD be chosen over a modern rail-to-rail op-amp for a precision filter stage?
TLE2142ACD is preferred when the priority is very low input offset voltage (maximum 1500 µV) and high CMRR (80 dB minimum) rather than output swing close to the rails. In a Sallen-Key active filter powered from ±12 V supplies, rail-to-rail output is unnecessary since the signal swing rarely exceeds ±8 V, and TLE2142ACD's superior precision reduces gain error and distortion at mid-scale compared to lower-cost rail-to-rail alternatives.
