Overview
TLE2064MDR from Texas Instruments is a quad FET-input operational amplifier with 36V supply capability, 1.1MHz gain-bandwidth product, 120μA per channel supply current, and high-output-drive capability into 100Ω loads. It serves as a precision, low-power signal conditioning amplifier in aerospace analog input modules and flight control units where wide temperature operation and JFET-input DC stability are required.
For engineers reviewing the TLE2064MDR datasheet, TLE2064MDR pinout, TLE2064MDR application, or TLE2064MDR equivalent, key selection criteria include its –55°C to 125°C operating range, SOIC-14 package, 1.1MHz GBW, 120μA/ch quiescent current, and JFET-input architecture enabling ultra-low input bias current (≤3 pA typical) and high common-mode rejection (≥65 dB).
Technical Context
The TLE2064MDR implements a JFET-input stage with on-chip Zener trimming for offset voltage calibration, delivering stable DC precision across military temperature ranges. Its architecture supports rail-to-rail output swing into 10kΩ and maintains ≥1.1MHz unity-gain bandwidth at ±5V and ±15V supplies.
It features low-noise performance (43 nV/√Hz at 1kHz), high slew rate (2.6 V/µs at ±15V), and robust output drive into low-impedance loads-enabling direct interfacing with ADC drivers, sensor front-ends, and active filters without external buffering.

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 |
|---|---|---|---|
| TLE2064CDR | Commercial-grade (0°C to 70°C), higher max VIO (6 mV vs. 6 mV), same SOIC-14 package and pinout. | Not qualified for extended temperature operation; unsuitable for engine bay or flight control hardware. | Select only for cost-sensitive non-military applications where ambient temperature remains tightly controlled. |
| OPA4134UA | Higher GBW (4 MHz), lower noise (8 nV/√Hz), but rated only to +85°C and lacks Zener-trimmed offset calibration. | Superior AC performance but insufficient long-term DC stability for unattended avionics deployments. | Prefer for audio or test equipment; avoid where 10-year drift budget must stay below 10 μV/month. |
Compared with TLE2064CDR and OPA4134UA, the TLE2064MDR uniquely combines military-temperature qualification, JFET-input ultra-low bias current, and factory-trimmed offset - making it the only option among the three qualified for full-authority digital engine control and flight control unit designs requiring zero maintenance calibration.

FAQ
What is the maximum supply voltage rating for the TLE2064MDR?
The TLE2064MDR 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 systems and legacy avionics rails without external regulation. Absolute maximum ratings must never be exceeded during transient conditions, and proper decoupling is required to maintain stability at upper supply limits. The TLE2064MDR maintains full specification compliance across this entire range.
Does the TLE2064MDR support rail-to-rail input or output operation?
The TLE2064MDR does not provide rail-to-rail input or output operation. Its common-mode input range extends from –11 V to +13 V at ±15 V supply, and output swing reaches ±14.5 V into 600 Ω - approximately 0.5 V within each rail. While not rail-to-rail, this performance exceeds standard bipolar op-amps and enables direct interfacing with many 12-bit and 14-bit ADCs without level-shifting circuitry. The TLE2064MDR's output stage is optimized for drive into low-impedance loads rather than rail compliance.
How does the input offset voltage of the TLE2064MDR compare to earlier BiFET op-amps?
The TLE2064MDR achieves a maximum input offset voltage of 6 mV over its full –55°C to +125°C operating range, significantly tighter than earlier-generation BiFET amplifiers (e.g., TL074: 15 mV max). This improvement stems from on-chip Zener trimming of the JFET-input stage, which reduces initial offset and improves long-term drift stability. At 25°C, typical VIO is just 0.1 mV, supporting high-gain DC-coupled configurations in precision sensor systems where calibration intervals exceed five years.
Can the TLE2064MDR drive a 100 Ω load continuously without damage or performance loss?
Yes - the TLE2064MDR is explicitly characterized and specified for continuous operation into 100 Ω loads, with output swing and distortion metrics validated under those conditions. Its high-output-drive architecture delivers ±12.5 V into 600 Ω and maintains stability with 100 pF capacitive loading. When driving 100 Ω, thermal considerations require attention: power dissipation rises to ~1.5 W per amplifier at full swing, so PCB copper area and airflow must be designed accordingly. The TLE2064MDR includes internal current limiting to prevent latch-up during short-circuit events.
What packaging options are available for the TLE2064MDR, and which is offered by Aetrix Electronics?
The TLE2064MDR is exclusively available in the SOIC-14 (D) package, measuring 8.65 mm × 6 mm, as confirmed by Texas Instruments' official orderable information. Other variants like TLE2064MJ (CDIP-14) and TLE2064MFK (LCCC-20) carry different suffixes and are distinct orderable parts. Aetrix Electronics stocks and distributes only the TLE2064MDR - the SOIC-14 version - with tape-and-reel packaging for automated SMT assembly. No PDIP, CDIP, LCCC, or flatpack variants are associated with the "DR" suffix.
