Product details
Overview
TLE2064MD from Texas Instruments is a quad FET-input operational amplifier with 36V supply capability, 1.1MHz gain-bandwidth product, 120μA per channel supply current, ±18V operating range, and high-output-drive capability into 100Ω loads. It serves as a precision, low-power signal conditioning amplifier in analog input modules for industrial control systems.
For engineers reviewing the TLE2064MD datasheet, TLE2064MD pinout, TLE2064MD application, or TLE2064MD equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options for aerospace-grade analog front-ends requiring extended temperature operation and JFET-input stability.
Technical Context
The TLE2064MD uses JFET-input transistors with on-chip Zener trimming for offset voltage control, enabling stable DC precision across –55°C to 125°C. Its architecture supports rail-to-rail output swing into high-current loads while maintaining low input bias current (±3 pA typical) and high common-mode rejection (72 dB at ±15V).
It operates with dual supplies from ±3.5V to ±18V and delivers 2.6 V/µs slew rate at ±15V, 10kΩ load, and exhibits 46° phase margin-optimized for unity-gain-stable configurations in feedback-critical sensor interfaces and engine control signal chains.

|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable closed-loop operation up to ~100 kHz with moderate gain in sensor amplification stages |
| Supply Current per Channel | 120 μA (typical) - allows four-channel operation within 500 μA total, suitable for battery-backed or energy-constrained systems |
| Input Offset Voltage | 6 mV (max, full temp range) - supports DC-coupled applications where sub-mV precision is not required but long-term stability matters |
| Common-Mode Input Range | –11 V to +13 V at ±15 V supply - accommodates wide-swing industrial sensor outputs without level-shifting |
| Output Drive Capability | Specified into 100 Ω - directly drives low-impedance loads such as transmission lines or ADC driver stages without external buffers |
| Slew Rate | 2.6 V/µs (at ±15 V) - sufficient for 10 kHz full-scale sine wave reproduction with <0.1% distortion |
| Operating Temperature | –55°C to +125°C - qualified for military, avionics, and downhole oilfield electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CD | Lower supply current (1.4 mA/ch), higher input noise (18 nV/√Hz), no M-temp grade | Limited to commercial temperature range (0°C to 70°C); unsuitable for aerospace or downhole use | Select when cost sensitivity outweighs temperature and power requirements |
| OPA4134UA | Lower VIO (100 μV max), lower noise (8 nV/√Hz), but higher ICC (2 mA/ch), no M-temp option | Optimized for audio-grade fidelity, not extended-temperature reliability or micro-power operation | Choose for high-fidelity instrumentation where precision exceeds robustness needs |
Compared with TL074CD and OPA4134UA, the TLE2064MD uniquely balances ultra-low power (120 μA/ch), extended temperature operation (–55°C to +125°C), and high-output-drive capability - making it irreplaceable in safety-critical, energy-constrained, and thermally extreme analog signal paths.

FAQ
What is the maximum supply voltage rating for the TLE2064MD?
The TLE2064MD has an absolute maximum supply voltage rating of ±19 V (38 V total), with recommended operation from ±3.5 V to ±18 V. This 36 V rating supports legacy industrial systems using ±15 V rails and newer designs leveraging ±18 V for increased dynamic range. Exceeding ±19 V risks permanent damage per the Absolute Maximum Ratings table in the TI datasheet SLOS193D.
Does the TLE2064MD support rail-to-rail input or output operation?
The TLE2064MD does not support rail-to-rail input operation - its common-mode input range is –11 V to +13 V at ±15 V supply - but it delivers rail-to-rail output swing into 10 kΩ loads (±14.5 V). For 100 Ω loads, output swing is specified at ±12.5 V. This asymmetric input range reflects its JFET-input architecture optimized for high-voltage precision, not low-voltage flexibility.
What is the input bias current specification for the TLE2064MD across temperature?
The TLE2064MD specifies input bias current of ±3 pA typical at 25°C, with a maximum of 30 nA across the full –55°C to +125°C operating range. This ultra-low IIB is enabled by its JFET-input stage and makes the TLE2064MD suitable for interfacing with high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes without significant offset error.
Can the TLE2064MD drive capacitive loads directly?
The TLE2064MD is unity-gain stable with capacitive loads up to 100 pF when properly decoupled (0.1 µF ceramic + 10 µF bulk capacitor on V+ and V–). Driving larger capacitive loads (>200 pF) may cause peaking or oscillation due to reduced phase margin; TI recommends adding a small series resistor (10–50 Ω) between output and load for stabilization in such cases, as documented in Section 7.1 of SLOS193D.
How does the TLE2064MD differ from the TLE2064ACD in terms of performance and qualification?
The TLE2064MD is the military-grade variant (M-suffix) with –55°C to +125°C operation, Zener-trimmed offset, and long-term drift spec (0.04 μV/month), whereas the TLE2064ACD is commercial-grade (C-suffix), rated 0°C to 70°C, with looser VIO tolerance (4 mV max) and no long-term drift characterization. Both share identical pinout and basic AC specs, but only the TLE2064MD meets MIL-PRF-38535 screening requirements for high-reliability applications.
