What are the key features of TLE2027MJG?
- Exceptional 131 dB typical common-mode rejection ratio (CMRR, minimum 96 dB) enables precise differential signal amplification in high-noise industrial and instrumentation environments
- Ultra-low input bias current of 90 nA maximum at 25°C minimizes offset errors in high-impedance sensor interfaces such as pH electrodes and piezoelectric transducers
- Voltage-feedback architecture with internal frequency compensation simplifies closed-loop stability design without external compensation networks
- Ceramic DIP package provides hermetic sealing for operation in harsh military and aerospace environments across extended temperature ranges
What is TLE2027MJG used for?
TLE2027MJG is designed for precision instrumentation amplifier circuits, strain gauge bridges, and medical measurement front-ends where high CMRR of at least 96 dB is critical for rejecting common-mode interference. Its ultra-low 90 nA bias current makes it an excellent fit for high-impedance electrochemical sensor interfaces and charge amplifier circuits in scientific instruments. The hermetic ceramic DIP package also suits military avionics, space-rated electronics, and harsh-environment industrial control systems where long-term reliability under thermal cycling is required.

Frequently Asked Questions
What is the CMRR of TLE2027MJG and how does it benefit differential signal measurements in noisy environments?
TLE2027MJG achieves a typical CMRR of 131 dB (minimum 96 dB), meaning a 1 V common-mode noise signal—such as 50 Hz or 60 Hz mains interference—is attenuated to less than 0.25 µV referred to the output at unity gain. This exceptional rejection level allows the amplifier to extract millivolt-level differential signals from bridge transducers, thermocouples, and strain gauges even in electrically noisy industrial or laboratory environments.
How does the 90 nA input bias current of TLE2027MJG affect accuracy in high-impedance sensor applications?
With a maximum input bias current of 90 nA at 25°C (150 nA absolute maximum), TLE2027MJG introduces less than 90 µV of offset error across a 1 MΩ source impedance. This is critical for pH electrode amplifiers, piezoelectric charge sensors, and capacitive pressure transducers where source impedances of 100 kΩ to 10 MΩ are common, and even nanoamp-level bias currents can produce measurable offset voltages that degrade measurement accuracy.
What temperature range and package does TLE2027MJG support for aerospace and military applications?
TLE2027MJG is housed in a hermetic ceramic DIP package (CDIP), which provides hermetic sealing suitable for military and aerospace qualification across the full military temperature range of -55°C to +125°C. The ceramic package withstands thermal cycling, vibration, and moisture ingress far better than plastic packages, making TLE2027MJG compliant with MIL-PRF-38535 and similar standards for avionics, satellite, and defense electronics.
When is TLE2027MJG preferred over a general-purpose op-amp for a precision bridge amplifier circuit?
A general-purpose op-amp such as an LM741 typically offers CMRR of only 70 dB to 90 dB and bias currents in the 200 nA to 500 nA range. TLE2027MJG's 131 dB CMRR and 90 nA bias current provide 40 dB better common-mode rejection and roughly 4× lower offset error in high-impedance bridge circuits. For a Wheatstone bridge strain gauge with a 350 Ω element and a 2 mV/V sensitivity at 5 V excitation, this translates to sub-1 µV amplifier-induced offset—making TLE2027MJG the correct choice when measurement accuracy below 0.01% full scale is required.
