Product details
Overview
TLE2061MD from Texas Instruments is a single-channel, JFET-input operational amplifier with 36V supply capability, 1.1MHz gain-bandwidth product, 120μA typical supply current, and high-output-drive capability into 100Ω loads. It serves as a precision, low-power signal conditioning amplifier in aerospace and industrial analog front-ends where wide voltage range and low noise are critical.
For engineers reviewing the TLE2061MD datasheet, TLE2061MD pinout, TLE2061MD application, or TLE2061MD equivalent, this device is selected for demanding analog input modules, flight control units, and full-authority engine control systems requiring FET-input stability, rail-to-rail output swing under load, and extended temperature operation (–55°C to 125°C).
Technical Context
The TLE2061MD uses JFET-input transistors with on-chip Zener trimming for offset voltage, enabling DC precision across its full military-grade operating range. Its architecture delivers low input bias current (≤30nA max), high common-mode rejection (≥65dB), and robust phase margin (≥58° at unity gain) even with capacitive loads up to 100pF.
It operates from ±3.5V to ±18V supplies, supports common-mode input ranges extending to within 1.6V of rails at ±5V and ±11V at ±15V, and maintains specified output drive into 100Ω loads - a key differentiator versus standard micropower op-amps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable unity-gain buffering and closed-loop bandwidths up to 140 kHz with full output swing. |
| Supply Current (typ) | 120 μA - allows battery-powered or energy-constrained systems to integrate precision amplification without compromising runtime. |
| Input Offset Voltage (max) | 3.1 mV at 25°C (TLE2061M grade) - supports accurate DC-coupled sensing in analog input modules without external trimming. |
| Output Drive Capability | Specified into 100Ω - delivers ≥±2.5V swing at ±5V supply, enabling direct interface to legacy ADC drivers and low-impedance transducers. |
| Operating Temperature Range | –55°C to +125°C - qualified for aerospace, defense, and downhole industrial applications where thermal resilience is mandatory. |
| Common-Mode Input Range | –11 V to +13 V at ±15 V supply - accommodates wide-swing sensor signals without level-shifting circuitry. |
| Slew Rate (typ) | 2.6 V/µs at ±15 V - supports fast transient response in closed-loop control feedback paths. |
Pinout & Package
Ceramic DIP-8 (JG) package: hermetically sealed, lead-free compatible, rated for 300°C soldering, 9.6 mm × 6.67 mm footprint including leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - electrically isolated; must be left unconnected or grounded per layout best practice. |
| 2 | VCC– | Negative supply terminal - accepts –3.5 V to –18 V; requires local decoupling for noise-sensitive analog sections. |
| 3 | IN+ | Non-inverting input - high-impedance JFET node (≥1 TΩ); sensitive to PCB leakage and guarding requirements. |
| 4 | IN– | Inverting input - matched to IN+ for CMRR optimization; routing symmetry critical for precision performance. |
| 5 | NC | No internal connection - electrically isolated; no routing or termination required. |
| 6 | OUT | Amplifier output - capable of sourcing/sinking >20 mA into 100Ω; requires output series resistor if driving long cables. |
| 7 | NC | No internal connection - electrically isolated; leave floating or tie to ground only if EMI mitigation is needed. |
| 8 | VCC+ | Positive supply terminal - accepts +3.5 V to +18 V; shares decoupling network with VCC– for balanced PSRR. |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Input bias current ≤30 nA max ensures minimal error in high-impedance sensor interfaces (e.g., piezoelectric or pH electrodes). |
| On-chip Zener-trimmed offset | Reduces initial VIO to ≤3.1 mV and limits drift to 1 μV/°C - eliminates need for external nulling in field-deployed systems. |
| High-output-drive specification | Guaranteed performance into 100Ω loads enables direct driving of transmission lines, relay coils, or legacy ADC inputs without buffer stages. |
| Military-grade temperature rating | –55°C to +125°C operation validated per MIL-PRF-38535 - supports qualification in avionics and oilfield electronics. |
| Low-noise performance | 43 nV/√Hz at 1 kHz and 1.1 µVPP (0.1–10 Hz) - suitable for precision instrumentation amplifiers and low-frequency signal chains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2061CD | Plastic DIP-8 package; commercial temperature range (0°C to 70°C); higher max VIO (3 mV vs. 3.1 mV for TLE2061M). | Limited to non-military ground-based equipment; lacks hermetic sealing and extended temperature validation. | Select when cost sensitivity outweighs environmental ruggedness and long-term stability requirements. |
| OPA2134UA | Bipolar-input design; lower noise (8 nV/√Hz); higher supply current (4 mA); SO-8 package only. | Not qualified for –55°C operation; unsuitable for high-impedance, ultra-low-current sensor nodes due to 200 pA bias current. | Prefer for audio or high-speed precision applications where noise dominates over power or input impedance constraints. |
Compared with TLE2061CD and OPA2134UA, the TLE2061MD uniquely combines military-grade temperature range, JFET-input impedance (>1 TΩ), and guaranteed 100Ω load drive - making it irreplaceable in certified avionics signal chains where all three attributes are simultaneously required.

FAQ
What is the maximum supply voltage rating for the TLE2061MD?
The TLE2061MD 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 high-voltage industrial sensor interfaces and legacy avionics power domains. Absolute maximum ratings must not be exceeded during power-up sequencing or fault conditions.
Does the TLE2061MD require external compensation for unity-gain stability?
No, the TLE2061MD is internally compensated and stable at unity gain. Its phase margin is ≥58° with 10 kΩ load and 100 pF capacitance, and improves to ≥75° with 100 Ω load. No external compensation components are needed for standard configurations, simplifying layout in space-constrained avionics modules.
What is the input bias current specification for the TLE2061MD over temperature?
The TLE2061MD exhibits input bias current ≤30 nA across its full operating range (–55°C to +125°C), with typical values of 3 pA at 25°C. This ultra-low bias enables accurate amplification of high-impedance sources such as piezoelectric sensors and photodiode transimpedance nodes without significant DC error.
Can the TLE2061MD drive a 100Ω load while maintaining specified output swing?
Yes - the TLE2061MD is explicitly characterized into 100Ω loads. At ±5 V supply, it delivers ≥±2.5 V output swing; at ±15 V, ≥±12.5 V. This capability is verified across temperature and process corners, distinguishing it from general-purpose micropower op-amps that degrade significantly below 1 kΩ.
Is the TLE2061MD pin-compatible with other devices in the TLE206x family?
Yes - all TLE206x single-amplifier variants (including TLE2061, TLE2061A, TLE2061B, and their M/AM/BM suffixes) share identical pinouts in the same package type. The TLE2061MD uses the JG (ceramic DIP-8) footprint, matching TLE2061AMJG and TLE2061BMJG, enabling drop-in substitution based on offset and drift requirements.
