Product details
Overview
TLE2061CD from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for high-voltage (±18 V), low-power (120 μA typical supply current), and high-output-drive applications. It delivers 1.1 MHz gain-bandwidth, ±4.9 V output swing into 10 kΩ at ±5 V supply, and 2.2 V/μs slew rate - enabling precision signal conditioning in engine control and flight control analog front-ends.
For engineers reviewing the TLE2061CD datasheet, TLE2061CD pinout, TLE2061CD application, or TLE2061CD equivalent, key selection criteria include its FET-input ultra-low bias current (±10 pA typ), 3 mV max input offset voltage (C-grade), SOIC-8 package compatibility, and specified drive into 100 Ω loads - critical for driving ADC drivers and sensor interface stages in harsh-environment industrial systems.
Technical Context
The TLE2061CD operates as a unity-gain-stable, internally compensated op-amp with JFET differential input stage, delivering rail-to-rail common-mode input range (–11 V to +13 V at ±15 V supply) and high open-loop gain (≥15 V/mV). Its design targets DC precision (low VIO, low drift) combined with AC performance (140 kHz full-swing bandwidth at ±5 V), making it suitable for closed-loop analog control where stability under capacitive loading matters.
It features low input noise (43 nV/√Hz at 1 kHz), negligible input bias current drift over temperature, and robust phase margin (46° at unity gain with 100 pF load), supporting stable operation in transimpedance and active filter configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±3.5 V to ±18 V - supports dual-rail operation across industrial and aerospace power domains. |
| Input Offset Voltage (max) | 3 mV at 25°C - enables accurate DC-coupled amplification without trimming in cost-sensitive systems. |
| Supply Current (typ) | 120 μA - allows battery-powered or energy-constrained designs to integrate precision amplification. |
| Gain-Bandwidth Product | 1.1 MHz - provides usable bandwidth for sensor signal conditioning up to ~100 kHz with moderate gain. |
| Slew Rate | 2.2 V/μs at ±5 V - ensures faithful reproduction of fast transients in engine knock detection or servo feedback paths. |
| Output Drive Capability | Specified into 100 Ω - directly interfaces with transmission lines, ADC reference buffers, or low-impedance actuator drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2061ACD | Lower 1.5 mV max VIO at 25°C; same SOIC-8 package and pinout. | Better DC accuracy for precision instrumentation where offset drift dominates error budget. | Select TLE2061ACD when system-level offset calibration is impractical and <1.5 mV initial error is required. |
| TL071CP | Higher 16 V/μs slew rate, 3 MHz GBW, but 200 μA supply current and no guaranteed 100 Ω drive spec. | Preferred for audio or wideband signal paths; less suited for low-power, high-drive industrial sensing. | Choose TL071CP only if bandwidth >1 MHz and slew rate >2 V/μs are mandatory, and power budget allows +80 μA per channel. |
Compared with TLE2061CD, TLE2061ACD improves DC precision without changing layout or supply, while TL071CP trades power efficiency and guaranteed low-impedance drive for higher speed - making TLE2061CD optimal for cost-sensitive, low-power, high-drive industrial analog signal chains.

FAQ
What is the maximum supply voltage for the TLE2061CD?
The TLE2061CD supports a maximum supply voltage of ±18 V (36 V total), with absolute maximum ratings specifying VCC+ − VCC− ≤ 38 V. Operation beyond ±18 V risks permanent damage. The device is characterized across ±3.5 V to ±18 V, and its output swing, CMRR, and slew rate remain fully specified within that range. Always observe derating guidelines for extended temperature operation.
Does the TLE2061CD require external compensation for unity-gain stability?
No, the TLE2061CD is internally compensated and unity-gain stable. Its phase margin is 46° at unity gain with a 100 pF capacitive load, verified per Figure 6-3 in the datasheet. This eliminates the need for external compensation components in standard inverting or non-inverting configurations, simplifying PCB layout and improving reliability in vibration-prone environments like engine bays or aircraft avionics bays.
What is the input offset voltage specification for the TLE2061CD?
The TLE2061CD has a maximum input offset voltage of 3 mV at 25°C and across the full 0°C to 70°C operating range. This value is guaranteed per Table 4-1 (C-suffix, P and D packages) and confirmed in Section 5.3. The typical offset is 0.1 mV, and the temperature coefficient is 1 μV/°C - enabling predictable drift behavior in uncalibrated systems where ambient temperature varies by ≤50°C.
Can the TLE2061CD drive a 100 Ω load effectively?
Yes, the TLE2061CD is explicitly specified for high-output-drive operation into 100 Ω loads. Per the "Features" section and electrical characteristics tables, its output swing is tested and guaranteed under 100 Ω conditions (e.g., ±2.5 V into 100 Ω at ±5 V supply). This capability avoids external buffer stages in applications such as driving ADC reference inputs, transmission line terminations, or low-impedance actuators - reducing bill-of-materials and board area.
Is the TLE2061CD pin-compatible with other TLE206x variants in SOIC-8?
Yes, all TLE206x devices in the SOIC-8 (D) package - including TLE2061CD, TLE2061ACD, TLE2061ID, and TLE2061AMD - share identical pinouts per Figure 4-2. Pin 1 (offset null) and Pin 7 (offset null) are NC in C/I-grade versions but retain mechanical alignment. This allows drop-in replacement for accuracy or temperature grade upgrades without PCB redesign, provided the system's supply and signal levels remain within the selected variant's specifications.
