Key Features
- Ultra-low maximum bias current of 60pA at 25 degrees C (30nA maximum over temperature) enables accurate signal conditioning from high-impedance sensors such as pH electrodes, photodiodes, and pyroelectric detectors
- 90dB typical common-mode rejection ratio (CMRR) with a 65dB minimum spec ensures excellent noise rejection in differential measurement applications
- Hermetic ceramic dual-in-line package (CDIP) provides military-grade protection against moisture, vibration, and thermal cycling, ideal for high-reliability aerospace and defense designs
- Voltage-feedback architecture with internal frequency compensation provides stable operation without external compensation components across a wide range of closed-loop gains
Applications
The TLE2064AMJ is used in precision instrumentation amplifiers, medical biosignal front-ends, and industrial sensor interfaces where extremely low input bias current and low noise are required to accurately amplify signals from high-impedance sources. Its hermetic CDIP package makes it suitable for aerospace, military, and oil exploration equipment operating in harsh thermal and humidity environments. The quad configuration allows four matched amplifier channels in a single package, reducing component count in multi-channel data acquisition systems.

Frequently Asked Questions
What makes the TLE2064AMJ suitable for high-impedance sensor interfaces?
The TLE2064AMJ features an exceptionally low bias current of 60pA maximum at 25 degrees C and 30nA maximum over the full temperature range. This ultra-low input bias current minimizes voltage errors when interfacing with high-impedance sources such as pH electrodes, piezoelectric sensors, and photodiode transimpedance circuits where even picoamp-level bias currents can cause significant offset errors.
How many op-amp channels does the TLE2064AMJ contain?
The TLE2064AMJ is a quad operational amplifier, containing four independent voltage-feedback op-amp channels in a single ceramic DIP package. Each channel offers matched performance specifications, including 90dB typical CMRR and 65dB minimum CMRR, making the quad configuration ideal for differential multi-channel data acquisition systems with tight channel-to-channel matching requirements.
What package does the TLE2064AMJ use and what does it mean for reliability?
The TLE2064AMJ is housed in a ceramic dual-in-line package (CDIP), which is a hermetically sealed ceramic package providing superior protection against moisture ingress, outgassing, and mechanical vibration compared to plastic DIPs. This makes it suitable for high-reliability applications including military, aerospace, and downhole oil exploration equipment where long service life under harsh environmental conditions is required.
What is the CMRR specification of the TLE2064AMJ?
The TLE2064AMJ achieves a typical CMRR of 90dB with a minimum guaranteed specification of 65dB. High CMRR is critical in differential measurement applications such as electrocardiography (ECG), strain gauge bridges, and industrial 4-20mA current loop receivers, where common-mode noise from power lines or electromagnetic interference must be rejected while preserving the small differential signal.
Is the TLE2064AMJ RoHS compliant?
The TLE2064AMJ carries a Pb-free code of 'Yes', indicating RoHS-compliant lead-free construction. Despite being in a legacy ceramic DIP package historically associated with leaded finishes, this version meets current RoHS environmental directives, making it suitable for designs that must comply with EU, China RoHS, and similar regulations.
