Product details
Overview
TLE2061ACDR from Texas Instruments is a single-channel FET-input operational amplifier with 1.1MHz gain-bandwidth product, 120μA typical supply current, and high-output-drive capability into 100Ω loads. It operates from ±3.5V to ±18V supplies, delivers ±14.5V output swing at ±15V supply into 600Ω, and is specified for 0°C to 70°C ambient operation - used in analog input modules requiring low-power precision amplification.
For engineers reviewing the TLE2061ACDR datasheet, TLE2061ACDR pinout, TLE2061ACDR application, or TLE2061ACDR equivalent, key selection criteria include input offset voltage (max 2.6mV at 25°C), slew rate (2.2–2.6 V/µs), common-mode input range (–11V to +13V at ±15V supply), and SOIC-8 packaging with tape-and-reel delivery.
Technical Context
The TLE2061ACDR uses JFET-input transistors for ultra-low input bias current (±10pA typ) and on-chip Zener trimming for DC precision. Its architecture supports rail-to-rail output swing relative to supply rails and maintains stable phase margin (46°) under unity-gain conditions with 10kΩ load and 100pF capacitance.
It achieves 1.1MHz GBW while consuming only 120μA per channel, enabling high AC performance in μPower systems. The device meets stringent noise requirements (43nV/√Hz at 1kHz) and delivers low THD (0.025%) at 10kHz, making it suitable for signal conditioning in safety-critical analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable unity-gain operation up to ~1.1 MHz with adequate phase margin |
| Supply Current | 120 μA (typ) - allows battery-powered or energy-constrained designs with minimal quiescent power draw |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2061CDR | Higher input offset voltage (3 mV max vs. 2.6 mV), same SOIC-8 package and electrical specs otherwise | Suitable for cost-sensitive industrial controls where tighter offset isn't required | Select when offset budget allows ≥3 mV and qualification testing confirms acceptable system accuracy |
| TL071CP | Higher supply current (1.4 mA vs. 120 μA), wider GBW (3 MHz), but no guaranteed 100Ω drive spec | Better for higher-speed general-purpose use, not optimized for μPower or low-Z drive | Choose only if speed >1.1MHz is mandatory and power budget permits 12× higher quiescent draw |
Compared with TLE2061CDR, the TLE2061ACDR offers tighter input offset tolerance (2.6 mV vs. 3 mV) for improved DC accuracy; compared with TL071CP, it delivers 12× lower supply current and guaranteed low-impedance drive - essential for battery-operated or high-fidelity analog input modules.

FAQ
What is the maximum operating supply voltage for the TLE2061ACDR?
The TLE2061ACDR supports a total supply voltage range of ±3.5V to ±18V, with absolute maximum rating of 38V between VCC+ and VCC–. Operation beyond ±18V risks exceeding absolute maximum ratings and is not recommended. The device is characterized across this full range, with key parameters like output swing and slew rate verified at both ±5V and ±15V conditions.
Does the TLE2061ACDR require external offset nulling components?
No, the TLE2061ACDR does not require external offset nulling. Pins 1 and 5 are designated NC (no connection) in this variant and are not internally connected to offset trim circuitry. The device uses on-chip Zener trimming to achieve its specified 2.6 mV max input offset voltage at 25°C - eliminating the need for manual calibration or external potentiometers.
Is the TLE2061ACDR pin-compatible with other TLE2061 variants in SOIC-8 packages?
Yes, the TLE2061ACDR is pin-compatible with all TLE2061x variants offered in the SOIC-8 (D) package, including TLE2061CDR, TLE2061IDR, and TLE2061ADR. Pin functions, physical dimensions, and thermal pad configuration match exactly - enabling drop-in replacement within the same temperature grade and offset specification tier.
What load impedance is the TLE2061ACDR specifically characterized to drive?
The TLE2061ACDR is explicitly characterized and specified for operation into 100Ω loads, as stated in its "High output drive, specified into 100Ω loads" feature. Electrical characteristics tables confirm output swing and distortion performance under 100Ω, 600Ω, and 10kΩ conditions - with 100Ω representing the most demanding low-impedance case validated in production test.
How does the TLE2061ACDR's input bias current compare to bipolar-input op-amps?
The TLE2061ACDR's input bias current is ±10 pA (typical), which is over 1000× lower than typical bipolar-input op-amps like the LM358 (±45 nA). This ultra-low bias current minimizes voltage error across high-impedance sources - for example, limiting error to <1 µV across a 100 MΩ sensor impedance - making it ideal for pH probes, photodiode transimpedance stages, and precision bridge amplifiers.
