Product details
Overview
TLE2061CPSR from Texas Instruments is a single-channel FET-input operational amplifier with 1.1 MHz gain-bandwidth product, 120 µA supply current (typ), and high-output-drive capability into 100 Ω loads. It operates from ±3.5 V to ±18 V supplies, delivers ±14.5 V output swing at ±15 V supply into 600 Ω, and is used in analog input modules for industrial control systems.
For engineers reviewing the TLE2061CPSR datasheet, TLE2061CPSR pinout, TLE2061CPSR application, or TLE2061CPSR equivalent, key selection criteria include its JFET-input low bias current (±10 pA typ), low 1/f noise (1.1 µVPP, 0.1–10 Hz), 2.6 V/µs slew rate at ±15 V, and SOIC-8 packaging suitable for space-constrained signal conditioning stages.
Technical Context
The TLE2061CPSR uses JFET-input transistors with on-chip Zener trimming for DC precision, delivering 72 dB CMRR and 93 dB PSRR at ±15 V supply. Its unity-gain bandwidth is 1.8 MHz with 58° phase margin into 10 kΩ//100 pF, supporting stable closed-loop operation in unity-gain buffers and active filters.
It features rail-to-rail input common-mode range (–11 V to +13 V at ±15 V supply) and open-loop output impedance of 280 Ω, enabling robust driving of moderate-impedance loads without external buffering in sensor front-end and DAC output stages.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2061CDR | Same SOIC-8 package and electrical specs; C-grade (0°C–70°C) with 3.1 mV max VIO, identical pinout and drive capability | Identical use cases; differs only in tape-and-reel packaging (R suffix) vs. tube (no suffix) | Select TLE2061CDR for automated SMT assembly; TLE2061CPSR is tube-packaged for prototyping or low-volume hand-soldering |
| TL071CP | Wider GBW (3 MHz), higher supply current (1.4 mA), no guaranteed 100 Ω drive; same SOIC-8 footprint but different pin 1 function (offset null) | Not suitable for low-power or high-output-drive requirements; requires external compensation for stability at unity gain | Choose TL071CP only if higher speed is critical and power/noise constraints are relaxed; verify layout compatibility due to pin 1 functional difference |
Compared with TLE2061CDR, TLE2061CPSR offers identical performance in tube packaging for manual assembly, while TL071CP trades ultra-low power and robust output drive for higher bandwidth and greater noise-making it unsuitable for battery-powered or low-impedance load applications where TLE2061CPSR excels.

FAQ
What is the operating temperature range for the TLE2061CPSR?
The TLE2061CPSR is rated for 0°C to 70°C ambient operation (C-suffix grade). It maintains specified performance-including 120 µA supply current, 3.1 mV max input offset voltage, and 2.6 V/µs slew rate-across this commercial temperature range, making it suitable for indoor industrial and test equipment applications.
Does the TLE2061CPSR require external offset nulling?
No, the TLE2061CPSR does not require external offset nulling. Pins 1 and 5 are designated NC (no connection) in the SOIC-8 package per the datasheet, as offset is trimmed internally using Zener diodes. The device guarantees ≤3.1 mV input offset voltage over 0°C–70°C without user adjustment.
Can the TLE2061CPSR drive a 100 Ω load effectively?
Yes, the TLE2061CPSR is explicitly characterized for high-output-drive operation into 100 Ω loads. At ±15 V supply, it delivers ±12.5 V output swing into 600 Ω and maintains usable linearity into 100 Ω, enabling direct interface with low-impedance cables, transmission lines, or power-stage inputs without external buffers.
What is the input impedance of the TLE2061CPSR?
The TLE2061CPSR features a FET-input stage with 6 TΩ common-mode input resistance and 540 GΩ differential input resistance (plus 3 pF capacitance). This ultra-high impedance minimizes loading on high-source-impedance sensors such as piezoelectric transducers, pH electrodes, and photodiode current sources.
Is the TLE2061CPSR pin-compatible with other TLE206x variants in SOIC-8?
Yes, all TLE206x devices in the SOIC-8 (D) package-including TLE2061CPSR, TLE2061CDR, TLE2061ACDR, and TLE2061IDR-share identical pinouts and footprints. Differences lie only in grade (C/I/M), offset voltage spec (3.1/2.6/1.9 mV max), and temperature range-not in connectivity or layout.
