Key Features
- JFET input stage with ultra-low bias current of 0.01 µA maximum, enabling accurate high-impedance sensor interfacing without loading the source
- 86 dB typical common-mode rejection ratio (CMRR) with 70 dB minimum, ensuring excellent noise immunity in single-supply and differential signal applications
- Low-power voltage-feedback architecture in an 8-pin DIP package, ideal for battery-operated and space-constrained precision analog circuits
Applications
The TL061CPE4 is well suited for high-impedance transducer signal conditioning, such as piezoelectric sensor amplifiers and pH electrode buffer stages, where the ultra-low 0.01 µA bias current prevents measurement errors. Its low-power consumption and JFET input make it an excellent choice for battery-powered instrumentation, audio preamplifiers, and integrator circuits that require minimal input loading. The standard 8-pin DIP package eases prototyping and through-hole production assembly for industrial sensing and test equipment.

Frequently Asked Questions
How does the TL061CPE4's input bias current compare to bipolar op-amps, and why does it matter for high-impedance sensors?
The TL061CPE4 features a maximum input bias current of 0.01 µA (10 nA) thanks to its JFET input stage, which is orders of magnitude lower than typical bipolar op-amps at 100 nA to 1 µA. This ultra-low bias current prevents significant voltage errors when the signal source impedance exceeds 1 MΩ, as in pH electrodes, piezo sensors, or photodiodes, making the TL061CPE4 ideal for precision high-impedance measurement circuits.
What common-mode rejection ratio does the TL061CPE4 provide, and how does that benefit differential signal designs?
The TL061CPE4 achieves a typical CMRR of 86 dB with a guaranteed minimum of 70 dB. A high CMRR means that common-mode noise such as 50 Hz or 60 Hz power-line interference appearing equally on both inputs is attenuated by 86 dB, leaving the differential signal intact. This makes the device reliable for bridge amplifier circuits and instrumentation front-ends in electrically noisy industrial environments.
Which low-power portable applications are a strong fit for the TL061CPE4 in an 8-pin DIP package?
The TL061CPE4 in an 8-pin DIP package is ideal for battery-operated data loggers, handheld test instruments, and audio filter stages where quiescent current must be minimized. Its low supply current combined with a wide supply range allows extended battery life in 9 V or ±5 V systems. The through-hole DIP format simplifies prototyping and small-volume production builds that require easy rework access on the PCB.
When should a designer consider TL061CPE4 as a lower-cost alternative to precision op-amps like TL071?
The TL061CPE4 is a cost-effective choice when the design requires JFET-input low bias current of 0.01 µA and 70 dB minimum CMRR but does not need the wider bandwidth or lower offset voltage of the TL071. For applications such as simple integrators, sample-and-hold amplifiers, and unity-gain buffers operating at signal frequencies below 1 MHz, the TL061CPE4 delivers sufficient performance at a lower cost in the same 8-pin DIP footprint.
