Key Features
- Precision voltage-feedback op-amp with 110 dB typical common-mode rejection ratio enabling high-accuracy signal conditioning in noisy environments
- Ultra-low input bias current maximum of 90 nA and input offset current maximum of 6 nA minimize measurement errors in high-impedance sensor circuits
- Internal frequency compensation in a ceramic dual-in-line package provides long-term stability for mil/aerospace and high-reliability industrial applications
Applications
TLE2021AMJGB is used in precision instrumentation amplifiers, strain-gauge bridges, and thermocouple signal conditioning circuits where sub-microvolt offset drift and high CMRR are critical. Its ceramic DIP package makes it suitable for military, aerospace, and high-reliability industrial equipment requiring wide operating temperature ranges. The part also serves as a precision integrator and low-drift comparator in scientific measurement and medical diagnostic equipment.

Frequently Asked Questions
How does TLE2021AMJGB's 110 dB typical CMRR benefit a thermocouple amplifier circuit?
A 110 dB common-mode rejection ratio means TLE2021AMJGB attenuates common-mode interference by a factor of over 316,000:1, allowing the amplifier to resolve thermocouple signals as small as 40 µV in the presence of 50 Hz or 60 Hz mains noise up to several volts. This makes it suitable for industrial temperature measurement systems where ground loops inject common-mode voltages of 1 V to 5 V onto the sensor leads.
What input bias current specification makes TLE2021AMJGB suitable for high-impedance sensor interfaces?
TLE2021AMJGB specifies a maximum input bias current of 90 nA at 25°C and a maximum input offset current of 6 nA. When driving a 1 MΩ source impedance, these currents produce a worst-case voltage error of only 90 µV due to bias and 6 µV due to offset mismatch, well within the budget for 16-bit ADC front-end circuits requiring less than 300 µV total offset error.
When is TLE2021AMJGB preferable to a plastic-packaged op-amp for aerospace instrumentation?
TLE2021AMJGB in a ceramic dual-in-line package outperforms plastic-packaged alternatives in aerospace applications operating across -55°C to +125°C because ceramic hermetic packaging prevents moisture ingress that degrades offset voltage by 500 µV or more over 10,000 hours of high-humidity exposure. It is also more tolerant of ionizing radiation environments where total dose above 10 krad can shift plastic-encapsulated devices beyond their 85 dB minimum CMRR specification.
