Product details
Overview
TLE2061MDG4 from Texas Instruments is a JFET-input, high-output-drive, micropower operational amplifier designed for precision analog signal conditioning in harsh environments. 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 use in flight control unit analog input stages where low power, rail-to-rail output swing, and wide temperature operation (–55°C to +125°C) are critical.
For engineers reviewing the TLE2061MDG4 datasheet, TLE2061MDG4 pinout, TLE2061MDG4 application, or TLE2061MDG4 equivalent, this device is selected when FET-input DC precision, high slew rate (2.6 V/µs at ±15 V), low noise (40 nV/√Hz at 1 kHz), and extended-temperature reliability must coexist with ultra-low quiescent current in aerospace and industrial sensor interfaces.
Technical Context
The TLE2061MDG4 uses JFET-input transistors with on-chip Zener trimming for offset voltage stability across –55°C to +125°C. Its architecture supports high common-mode rejection (72 dB min at ±15 V) and supply-voltage rejection (75 dB min), making it suitable for noisy, high-voltage sensor front-ends.
It features a unity-gain bandwidth of 1.8 MHz and phase margin of 58° (RL = 10 kΩ, CL = 100 pF), ensuring stable closed-loop operation without external compensation in most gain configurations. Output stage is optimized for driving low-impedance loads down to 100 Ω while maintaining >12 V peak-to-peak swing at ±15 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable unity-gain buffering and low-noise amplification up to ~100 kHz with gain ≥10. |
| Supply Current (typ) | 120 μA - allows battery-powered or energy-constrained systems (e.g., remote engine sensors) to operate for years on small cells. |
| Input Offset Voltage (max) | 3.1 mV at 25°C (TLE2061M grade) - supports DC-coupled signal chains requiring <0.1% accuracy over temperature. |
| Slew Rate (typ) | 2.6 V/µs at ±15 V - ensures faithful reproduction of fast transients in engine control feedback loops. |
| Common-Mode Range | –11 V to +13 V at ±15 V supply - accommodates signals referenced to non-ground potentials in automotive and avionics harnesses. |
| Output Drive Capability | Specified into 100 Ω - directly interfaces with ADC drivers, cable drivers, or low-Z transducer loads without external buffers. |
| Operating Temperature | –55°C to +125°C - qualified for military/aerospace applications including flight control units and full-authority digital engine control (FADEC). |
Pinout & Package
Ceramic DIP-8 (JG) package: hermetically sealed, leaded, 9.6 mm × 6.67 mm footprint, rated for high-reliability extended-temperature operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No connection - unused terminal; must be left floating or grounded per layout best practices. |
| 2 | VCC– | Negative supply rail - connects to system ground or negative voltage; decoupling capacitor required within 1 cm. |
| 3 | IN+ | Non-inverting input - high-impedance (≥1 TΩ) FET node; sensitive to leakage; requires guarded trace routing. |
| 4 | IN– | Inverting input - matched to IN+ for CMRR optimization; feedback network connects here in standard configurations. |
| 5 | NC | No connection - unused terminal; must be left floating or grounded per layout best practices. |
| 6 | NC | No connection - unused terminal; must be left floating or grounded per layout best practices. |
| 7 | OUT | Amplifier output - capable of ±12.5 V swing into 600 Ω at ±15 V supply; drives capacitive loads ≤100 pF unstably without isolation resistor. |

| Zener-trimmed offset voltage | Max 3.1 mV over full temperature range - eliminates need for external nulling circuitry in precision DC signal paths. |
| High-output-drive capability | Specified performance into 100 Ω - replaces discrete buffer stages in analog output modules, reducing BOM count and board area. |
| Low input voltage noise | 40 nV/√Hz at 1 kHz - preserves SNR in low-level signal amplification (e.g., thermocouple, strain gauge front-ends). |
| Extended temperature rating | –55°C to +125°C operation - meets MIL-PRF-38535 requirements for flight-critical subsystems without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FET-input, extended-temperature op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2134UA | Higher 8 MHz GBW, lower 8 nV/√Hz noise, but only rated to +85°C; SO-8 package only. | Not qualified for flight-critical or extended-temperature industrial use; better suited for audio or lab instrumentation. | Select only if ambient temperature stays below 85°C and higher speed/noise performance justifies reduced ruggedness. |
| LMC6061IM | CMOS input (lower bias current: 0.02 pA), but 0.12 MHz GBW and no 100 Ω drive spec; rated –55°C to +125°C. | Limited to ultra-high-Z, low-bandwidth applications (e.g., pH meters); cannot replace TLE2061MDG4 in dynamic control loops. | Choose only for ultra-low-input-current DC sensing where speed and drive are secondary. |
Compared with OPA2134UA and LMC6061IM, the TLE2061MDG4 uniquely balances extended-temperature operation, 100 Ω drive capability, and micropower consumption - making it irreplaceable in FADEC and flight control analog signal chains where all three attributes are simultaneously mandatory.

FAQ
What is the maximum supply voltage for the TLE2061MDG4?
The TLE2061MDG4 supports a maximum supply voltage of ±18 V (36 V total). Absolute maximum ratings specify VCC+ − VCC− ≤ 38 V, but recommended operating conditions limit it to ±18 V for reliable long-term performance. Exceeding ±18 V risks parametric shift or permanent damage, especially at elevated temperatures.
Does the TLE2061MDG4 support rail-to-rail input or output?
The TLE2061MDG4 does not support rail-to-rail input or output. Its common-mode input range is –11 V to +13 V at ±15 V supply, and output swing is typically ±12.5 V into 600 Ω - meaning it cannot reach within ~2.5 V of either rail. This is typical for JFET-input op-amps of this era and voltage class.
Is the TLE2061MDG4 pin-compatible with other TLE2061 variants like TLE2061CD or TLE2061ID?
No - the TLE2061MDG4 uses the ceramic DIP-8 (JG) package, while TLE2061CD and TLE2061ID use SOIC-8 and PDIP-8 packages respectively. Pin numbering and physical dimensions differ; PCB layout and thermal design are not interchangeable. Only the pin *function* (not mechanical fit) is consistent across the family.
What is the input bias current specification for the TLE2061MDG4 at –55°C?
At –55°C, the TLE2061MDG4 exhibits an input bias current of ≤30 nA (max), per its M-grade electrical characteristics table. This is significantly higher than the 3 pA typical value at 25°C due to JFET leakage increase at cryogenic temperatures - a known behavior that must be accounted for in ultra-high-impedance sensor designs.
Can the TLE2061MDG4 drive a 100 pF capacitive load without oscillation?
The TLE2061MDG4 is not unconditionally stable into 100 pF. With RL = 10 kΩ and CL = 100 pF, phase margin is 58° - acceptable but marginal. For CL > 50 pF, TI recommends adding a 10–100 Ω isolation resistor between OUT and the capacitive load to maintain stability. Driving pure 100 pF loads directly may cause ringing or oscillation.
