Product details
Overview
TLE2061ACDRG4 from Texas Instruments is a single-channel FET-input operational amplifier optimized for high-output-drive, low-power, and high-voltage operation. It delivers 1.1 MHz gain-bandwidth, 120 μA supply current (typ), ±18 V max supply range, and specified output drive into 100 Ω loads - enabling precision signal conditioning in engine control units and flight control analog front-ends.
For engineers reviewing the TLE2061ACDRG4 datasheet, TLE2061ACDRG4 pinout, TLE2061ACDRG4 application, or TLE2061ACDRG4 equivalent, key selection criteria include its JFET-input architecture, low 1.9 mV max input offset voltage (25°C), 46° phase margin at unity gain, and SOIC-8 packaging with industry-standard pinout for drop-in replacement in legacy BiFET designs.
Technical Context
The TLE2061ACDRG4 uses JFET-input transistors with on-chip Zener trimming for DC precision, delivering low input bias current (±10 pA typ) and high input impedance (6 TΩ || 1 pF common-mode). Its architecture supports rail-to-rail output swing capability under light loads and maintains stability with capacitive loads up to 100 pF.
It operates across 0°C to 70°C ambient temperature, supports dual supplies from ±3.5 V to ±18 V, and achieves 2.2 V/µs slew rate (±5 V) and 2.6 V/µs (±15 V) - making it suitable for medium-speed closed-loop control where power efficiency and noise performance are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable unity-gain operation with bandwidth sufficient for sensor amplification and feedback loops up to ~140 kHz full-swing. |
| Supply Current per Channel | 120 μA (typ) - allows battery-powered or energy-constrained systems to integrate precision amplification without compromising runtime. |
| Input Offset Voltage (max) | 1.9 mV at 25°C - ensures <0.1% error in 2 V full-scale industrial analog input modules without external trimming. |
| Output Drive Capability | Specified into 100 Ω - supports direct driving of low-impedance loads such as ADC reference buffers or actuator interface stages. |
| Common-Mode Input Range | –11 V to +13 V at ±15 V supply - accommodates wide-range sensor signals (e.g., thermocouple, strain gauge) without level-shifting circuitry. |
| Slew Rate | 2.6 V/µs (±15 V) - supports settling within 10 µs to 0.01% for 10 V step inputs, meeting timing requirements in digital engine control sampling. |
| Phase Margin | 46° at unity gain - guarantees unconditional stability with 10 kΩ load and 100 pF capacitance, simplifying PCB layout in noisy environments. |
Pinout & Package
Package: SOIC-8 (D package), 4.9 mm × 6 mm body, gull-wing leads, RoHS-compliant, tape-and-reel (R suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No connection - unused terminal; must remain unconnected per TI design guidelines. |
| 2 | IN− | Inverting input - high-impedance JFET node; requires guarded trace routing to minimize leakage-induced offset drift. |
| 3 | IN+ | Non-inverting input - matched high-impedance node; differential pair input for precision DC-coupled amplification. |
| 4 | VCC− | Negative supply rail - connects to system ground or negative rail; decoupling capacitor (0.1 μF) required within 5 mm. |
| 5 | NC | No connection - unused terminal; electrically isolated from die; no internal bond wire. |
| 6 | NC | No connection - unused terminal; no internal function; leave floating or grounded per layout best practice. |
| 7 | VCC+ | Positive supply rail - accepts up to +18 V; symmetric dual-supply operation enables bipolar signal handling. |
| 8 | OUT | Amplifier output - capable of sourcing/sinking >10 mA into 100 Ω; output stage designed for low distortion into reactive loads. |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Enables ultra-low input bias current (±10 pA typ) for high-source-impedance sensor interfaces like piezoelectric or pH electrodes. |
| High-output-drive specification | Guaranteed performance into 100 Ω loads - eliminates need for external buffer stages in actuator driver circuits. |
| Low-noise floor (43 nV/√Hz @ 1 kHz) | Reduces signal degradation in precision analog input modules where SNR > 80 dB is required over 20 Hz–20 kHz band. |
| Zener-trimmed offset voltage | Delivers 1.9 mV max VIO at 25°C - reduces calibration overhead in factory-programmed flight control unit signal chains. |
| Wide supply range (±3.5 V to ±18 V) | Supports direct integration into legacy 15 V industrial control rails and modern low-voltage embedded systems without level translation. |

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 |
|---|---|---|---|
| TLE2061CDR | Same SOIC-8 package and pinout; higher 3 mV max VIO (C-grade vs A-grade); identical AC specs and supply range. | Acceptable for non-critical analog paths where 0.1% gain error is tolerable; not qualified for aerospace or automotive functional safety tiers. | Select when cost sensitivity outweighs offset-critical performance; verify system-level calibration budget. |
| TL071CP | SOIC-8 pin-compatible; lower 1.5 mV max VIO but higher 1.8 mA supply current; 3 MHz GBW but inferior 10 nV/√Hz noise floor. | Better for high-speed AC coupling; unsuitable for battery-powered or low-noise DC applications due to 15× higher quiescent current. | Choose only if bandwidth >1 MHz and noise <50 nV/√Hz are secondary to cost and availability. |
Compared with TLE2061ACDRG4, TLE2061CDR trades guaranteed low offset for lower cost in non-safety-critical roles, while TL071CP offers higher speed at the expense of 15× higher power and degraded noise - making TLE2061ACDRG4 optimal for precision, low-power, high-voltage analog signal chains.

FAQ
What is the maximum supply voltage rating for the TLE2061ACDRG4?
The TLE2061ACDRG4 has an absolute maximum supply voltage rating of ±18 V (36 V total), with recommended operating range from ±3.5 V to ±18 V. Operation beyond ±18 V risks permanent damage per TI's Absolute Maximum Ratings table. The device maintains specified performance across this full range, including output swing and CMRR.
Does the TLE2061ACDRG4 support single-supply operation?
Yes, the TLE2061ACDRG4 supports single-supply operation with VCC+ referenced to ground and VCC− tied to ground. Its common-mode input range extends to within 1.6 V of the negative rail (ground), and output swings to within ~2 V of ground under 10 kΩ load - enabling use in 5 V or 12 V systems with appropriate input biasing.
What is the input offset voltage specification for the TLE2061ACDRG4 at 25°C?
The TLE2061ACDRG4 has a maximum input offset voltage of 1.9 mV at 25°C, with typical value of 0.1 mV. This A-grade specification is tighter than the standard C-grade (3 mV max) and reflects Zener-trimmed precision for applications demanding minimal DC error without external calibration.
Is the TLE2061ACDRG4 pin-compatible with other TLE206x variants?
Yes - all TLE2061x variants in SOIC-8 (D) package share identical pinout per Figure 4-2 of the datasheet. TLE2061ACDRG4, TLE2061CDR, and TLE2061IDR use the same 1–8 pin mapping, enabling direct substitution where temperature grade and offset spec align with system requirements.
What is the thermal performance of the TLE2061ACDRG4 in SOIC-8 package?
The TLE2061ACDRG4 in SOIC-8 (D) package has a junction-to-ambient thermal resistance (θJA) of 160°C/W. At 120 μA supply current and ±15 V operation, power dissipation remains below 3.6 mW, resulting in negligible self-heating (<0.6°C rise) - ensuring stable offset and drift behavior in sealed enclosures or stacked PCB layouts.
