What are the key features of TL061IPE4?
- JFET input stage delivering 0.02 µA maximum bias current for high-impedance sensor interfaces with minimal loading error
- 86 dB typical common-mode rejection ratio ensuring strong noise immunity in differential measurement applications
- Low-power voltage-feedback architecture reducing quiescent supply current compared to standard bipolar op-amps of equivalent bandwidth
- Internal frequency compensation eliminating external phase-correction components and simplifying single-supply and split-supply circuit designs
- Industrial-grade 8-pin DIP (PDIP) package supporting through-hole prototyping and repair in demanding -40°C to 85°C environments
What is TL061IPE4 used for?
The TL061IPE4 is optimized for battery-operated instrumentation amplifiers, sample-and-hold circuits, and high-impedance pH or ion-selective electrode interfaces where its 0.02 µA bias current and JFET inputs prevent signal loading errors. Its 80 dB minimum CMRR makes it suitable for differential signal conditioning in industrial sensors, thermocouple amplifiers, and bridge-measurement front ends that must reject common-mode noise from power lines. The through-hole 8-pin DIP footprint accommodates rapid prototyping and field repair in legacy industrial equipment.

Frequently Asked Questions
How does the 0.02 µA maximum bias current of TL061IPE4 benefit high-impedance sensor interfaces?
A maximum input bias current of 0.02 µA means the TL061IPE4 draws less than 20 nA from a sensor's output node, limiting the voltage error across a 1 MΩ source impedance to just 20 mV. This makes it far superior to standard bipolar op-amps drawing 50 nA to 500 nA for pH probes, piezo sensors, and charge-amplifier circuits where loading-induced offset would corrupt the measurement.
What CMRR specification does TL061IPE4 offer, and why does that matter for industrial differential measurements?
The TL061IPE4 achieves a minimum 80 dB and typical 86 dB common-mode rejection ratio, attenuating a 1 V common-mode noise signal at the inputs to under 50 µV at the output. This level of rejection is essential in bridge-sensor and thermocouple amplifiers located near variable-frequency drives or switch-mode power supplies that inject tens of millivolts of common-mode interference onto signal lines.
For a portable battery-powered data logger, how does TL061IPE4 compare to a standard TL071 in terms of supply current?
The TL061IPE4 is the low-power sibling of the TL071 family, consuming roughly 200 µA per amplifier versus the TL071's 1.4 mA quiescent current. In a 3-channel data logger running on a 1000 mAh lithium cell, switching to TL061 op-amps can extend continuous operation from approximately 24 hours to over 160 hours, a 6x improvement attributable solely to the reduced front-end quiescent draw.
Which circuit topologies benefit most from the internal frequency compensation built into TL061IPE4?
Internal compensation makes TL061IPE4 unity-gain stable, so inverting amplifiers, voltage followers, and integrators require no external capacitor on the compensation pin to prevent oscillation. This simplifies Sallen-Key active filter stages and precision integrator circuits where an uncompensated op-amp would demand careful external capacitor selection to maintain 45° phase margin across the full operating temperature range of -40°C to 85°C.
When is the 8-pin DIP package of TL061IPE4 preferred over an SOIC version for prototyping or repair work?
The 8-pin DIP package with 2.54 mm pin pitch allows direct insertion into breadboards and standard IC sockets, cutting prototype wiring time to under 5 minutes versus the 30-minute soldering effort a surface-mount SOIC-8 requires on adapter boards. For field repair of legacy 1990s to 2000s-era industrial instruments that standardized on DIP sockets, the TL061IPE4 DIP variant is often the only pin-compatible drop-in replacement available.
