Key Features
- Ultra-low input bias current of 0.4 nA typical enables high-impedance sensor signal conditioning
- 3 MHz gain-bandwidth product with 86 dB common-mode rejection ratio for precision amplifier designs
- JFET input stage provides high input impedance and low offset current for pH and photodetector circuits
- 8-pin PDIP package allows simple prototyping and breadboard testing in dual-supply op-amp applications
Applications
The TL080CPE4 is well suited for high-impedance analog signal conditioning in applications such as pH electrode amplifiers, photodetector transimpedance stages, and active filter designs. Its JFET input stage provides the sub-nanoamp bias current needed to interface with high-source-impedance sensors without introducing significant offset errors. It also performs in audio signal processing, precision integrators, and sample-and-hold circuits operating from ±5 V to ±15 V dual supply rails.

Frequently Asked Questions
What is the gain-bandwidth product of TL080CPE4 and how does it limit closed-loop bandwidth?
The TL080CPE4 has a gain-bandwidth product of 3 MHz. In a non-inverting configuration with a closed-loop gain of 10, the -3 dB bandwidth is approximately 300 kHz. For unity-gain buffers, the full 3 MHz bandwidth is available, making it suitable for audio and moderate-speed instrumentation circuits on ±15 V supplies.
How does TL080CPE4's input bias current compare to bipolar-input op-amps for high-impedance sensors?
The TL080CPE4 has a typical input bias current of only 0.4 nA thanks to its JFET input stage, versus 50 nA to 500 nA for standard bipolar op-amps. This 100× reduction makes the TL080CPE4 the preferred choice for pH meters, piezoelectric sensors, and pyroelectric detectors where source impedances exceed 1 MΩ.
What supply voltage range does TL080CPE4 require and is single-supply operation possible?
The TL080CPE4 is designed for dual-supply operation from ±5 V to ±18 V, with a typical specification at ±15 V. It is not optimized for single-supply use since the input common-mode range does not include the negative rail, so rail-to-rail designs should use a dedicated single-supply op-amp with 70 dB or better CMRR.
Which filter topologies work well with TL080CPE4 at audio frequencies?
The TL080CPE4's 3 MHz GBW and 70 dB minimum CMRR make it a strong candidate for Sallen-Key and multiple-feedback active filters up to approximately 100 kHz with gains below 30. Its low 0.4 nA bias current keeps DC offset errors below 1 mV even with 1 MΩ feedback resistors, preserving filter accuracy across the 20 Hz to 20 kHz audio band.
