What are the key features of TLC2652AMJGB?
- Chopper-stabilized auto-zero architecture achieving near-zero input offset voltage drift over temperature for ultra-precision DC measurements
- 120 dB minimum CMRR (140 dB typical) with 60 fA bias current at 25°C for high-accuracy differential signal amplification
- Military-grade ceramic DIP package with Pb-free construction providing long-term reliability for precision instrumentation applications
What is TLC2652AMJGB used for?
The TLC2652AMJGB is designed for precision DC and low-frequency measurement applications where ultra-low input offset voltage and near-zero drift are critical, such as strain gauge amplifiers, thermocouple signal conditioners, and precision weigh-scale circuits. Its 120 dB minimum CMRR and chopper-stabilization eliminate the need for periodic calibration in long-term data logging and industrial sensor front-end designs. The ceramic DIP package suits military-qualified precision analog systems and laboratory instrumentation requiring high environmental stability.

Frequently Asked Questions
What CMRR specification does TLC2652AMJGB achieve and why is this critical for strain gauge circuits?
TLC2652AMJGB achieves a minimum CMRR of 120 dB with a typical value of 140 dB, which means common-mode noise signals such as 50/60 Hz mains interference are attenuated by a factor of over 1,000,000 relative to the differential signal. For a strain gauge bridge where the signal may be only a few microvolts on a 5 V common-mode voltage, this 120 dB CMRR ensures the amplified output represents the true bridge imbalance rather than common-mode noise artifacts.
How does the chopper-stabilized architecture of TLC2652AMJGB eliminate input offset voltage drift in precision weigh-scale designs?
The chopper-stabilization technique in TLC2652AMJGB periodically nulls the internal offset voltage by switching the input signal and subtracting the offset component, achieving effective input offset voltages below 1 µV with drift well under 0.01 µV/°C. In a precision weigh-scale where a 100 g resolution requires amplifying signals to better than 10 µV accuracy across a -40°C to 85°C temperature range, this auto-zero mechanism eliminates the need for manual offset trimming resistors or periodic factory recalibration.
What input bias current does TLC2652AMJGB draw at 25°C and how does this affect source impedance selection?
At 25°C the TLC2652AMJGB has a maximum input bias current of 60 fA (0.00006 µA) and an average maximum of 0.5 pA over temperature, allowing it to interface with source impedances up to several gigaohms without generating significant voltage error. For a 1 GΩ sensor source, 60 fA of bias current produces only 60 µV of offset — negligible compared to the 120 dB CMRR performance — making TLC2652AMJGB suitable for pH meter electrodes and picoampere-level photodiode transimpedance stages.
