Product details
Overview
TLE2061CDRG4 from Texas Instruments is a single-channel FET-input operational amplifier optimized for high-output-drive, low-power, and high-voltage operation (±18 V supply). It delivers 1.1 MHz gain-bandwidth, 2.2 V/µs slew rate at ±5 V, 120 µA supply current, 3.1 mV max input offset voltage (C-grade), and rail-to-rail output swing into 10 kΩ loads - enabling precision signal conditioning in engine control and flight systems.
For engineers reviewing the TLE2061CDRG4 datasheet, TLE2061CDRG4 pinout, TLE2061CDRG4 application, or TLE2061CDRG4 equivalent, key selection criteria include its JFET-input architecture for ultra-low bias current (±10 pA typ), high CMRR (82 dB), low 1/f noise (1.1 µVPP, 0.1–10 Hz), and SOIC-8 packaging suitable for space-constrained industrial analog modules.
Technical Context
The TLE2061CDRG4 uses a JFET-input stage with on-chip Zener trimming for DC precision, supporting stable operation across ±3.5 V to ±18 V supplies. Its unity-gain-stable design features 46° phase margin with 100 pF capacitive load and delivers full-swing output even into 100 Ω loads when configured as a buffer or driver.
It operates over 0°C to 70°C (C-suffix), exhibits 1 μV/°C input offset drift, and maintains 540 GΩ || 3 pF differential input impedance - making it suitable for high-impedance sensor interfacing where leakage and thermal drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable closed-loop operation up to ~100 kHz with moderate gain (e.g., AV = 10). |
| Supply Current | 120 µA typical - supports battery-powered or energy-sensitive systems without compromising AC performance. |
| Input Offset Voltage | 3.1 mV max (25°C) - ensures ≤0.3% error in 1 V full-scale measurement without trimming. |
| Slew Rate | 2.2 V/µs (±5 V, RL = 10 kΩ) - supports clean 10 kHz sine wave output at 2 VPP with <0.025% THD. |
| Common-Mode Rejection | 82 dB - rejects >12× common-mode interference in noisy engine bay or avionics environments. |
| Input Bias Current | ±10 pA typical - preserves signal integrity from high-impedance sources like piezoelectric sensors or pH electrodes. |

| 7 | Offset Null (NC on TLE2061CDRG4) | No connection - pin unused; no external nulling required for C-grade accuracy spec. |
| 8 | NC | No internal connection - electrically isolated; may be grounded for EMI reduction. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2061ACD | Lower VIO (2.6 mV max) and tighter offset drift spec; otherwise identical SOIC-8 pinout and electrical behavior. | Preferred for higher-accuracy sensor front-ends where 0.5 mV VIO reduction improves system calibration margin. | Select TLE2061ACD when offset-critical DC performance justifies minor cost premium over TLE2061CDRG4. |
| TL071CP | Same SOIC-8 package but BiFET architecture; higher supply current (1.4 mA), lower GBW (3 MHz), and no guaranteed 100 Ω drive spec. | Suitable for general-purpose audio or non-critical analog circuits; not recommended for low-power or high-drive applications. | Choose TL071CP only for legacy designs where cost is primary constraint and 120 µA quiescent current is not required. |
Compared with TLE2061ACD, TLE2061CDRG4 trades 0.5 mV higher offset for broader availability and lower cost; versus TL071CP, it delivers 12× lower supply current and verified 100 Ω drive - making it superior for modern embedded control and portable instrumentation.

FAQ
What is the maximum supply voltage rating for the TLE2061CDRG4?
The TLE2061CDRG4 supports a total supply voltage (VCC+ − VCC−) up to 38 V, with recommended operating range of ±3.5 V to ±18 V. This allows use in both low-voltage portable systems and traditional ±15 V industrial equipment without external regulation.
Does the TLE2061CDRG4 require external offset nulling components?
No. The TLE2061CDRG4 is the standard C-grade SOIC-8 variant with no internal offset null circuitry; pins 1 and 7 are unconnected (NC). Its 3.1 mV max input offset voltage is trimmed at wafer level and does not require user adjustment.
Can the TLE2061CDRG4 drive a 100 Ω load effectively?
Yes. The TLE2061CDRG4 is explicitly specified for high-output-drive operation into 100 Ω loads per its datasheet. At ±5 V supply, it delivers ±2.5 V output swing into 100 Ω, enabling direct interface with low-impedance transducers, transmission lines, or power-stage inputs without added buffering.
What is the input bias current specification for the TLE2061CDRG4 at 25°C?
The TLE2061CDRG4 exhibits ±10 pA typical input bias current at 25°C, with a maximum of 2 nA over the full 0°C to 70°C operating range. This ultra-low value stems from its JFET-input architecture and makes it ideal for interfacing with high-impedance sources such as photodiodes or piezoelectric sensors.
Is the TLE2061CDRG4 unity-gain stable?
Yes. The TLE2061CDRG4 is internally compensated for unity-gain stability. It maintains ≥46° phase margin with a 100 pF capacitive load at unity gain, ensuring reliable operation in voltage-follower, active filter, and transimpedance configurations without external compensation.
