Product details
Overview
TLE2022AMDR from Texas Instruments is a dual-channel, military-grade precision operational amplifier using the Excalibur bipolar process. It delivers 2 MHz unity-gain bandwidth, 0.65 V/µs slew rate, and 100 µV max input offset voltage at ±15 V supply, operating across –55°C to +125°C. It enables low-level signal conditioning in single- or split-supply instrumentation, sensor interfaces, and aerospace data acquisition systems.
For engineers reviewing the TLE2022AMDR datasheet, TLE2022AMDR pinout, TLE2022AMDR application, or TLE2022AMDR equivalent, key selection criteria include its guaranteed military-temperature performance, phase-reversal protection, rail-to-rail input capability (down to negative rail), low 700 µA max supply current per channel at ±15 V, and stable long-term offset drift of 0.006 µV/month.
Technical Context
The TLE2022AMDR employs a complementary bipolar Excalibur process with isolated vertical PNP transistors, enabling significantly improved unity-gain bandwidth and slew rate versus legacy precision op-amps like the OP21. Its bias circuit ensures exceptional parameter stability over time and temperature.
It features phase-reversal protection that prevents output state inversion when either input falls below the negative supply rail - a critical reliability feature for sensor front-ends in harsh environments. The device supports both 5 V single-supply and ±15 V operation with a common-mode input range extending to the negative rail.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual amplifier - enables matched-pair signal processing in compact space-constrained designs. |
| Unity-gain bandwidth | 2 MHz - supports stable closed-loop operation up to ~1.7 MHz with adequate phase margin (52°) at ±15 V. |
| Slew rate | 0.65 V/µs - enables accurate reproduction of signals up to ~200 kHz full-power sine wave at ±10 V output swing. |
| Input offset voltage (max) | 120 µV at 25°C, 300 µV over full –55°C to +125°C range - ensures high dc accuracy in precision gain stages and reference buffers. |
| Supply current (max) | 700 µA per channel at ±15 V - achieves precision performance with ultra-low power consumption suitable for battery-backed or thermally constrained systems. |
| Input bias current (max) | 70 nA at 25°C - minimizes voltage error in high-impedance sensor interfaces (e.g., piezoelectric or photodiode amplifiers). |
| Common-mode input range | Includes negative rail (–15 V) at ±15 V supply - allows direct interfacing with ground-referenced sensors without level-shifting circuitry. |

Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents catastrophic output polarity flip when inputs go below VCC–, eliminating need for external clamping diodes in sensor front-ends. |
| Military temperature rating | Characterized and guaranteed over –55°C to +125°C - eliminates derating or qualification testing for defense and avionics deployments. |
| Low long-term drift | 0.006 µV/month typical offset voltage drift - ensures calibration stability over multi-year system lifetimes without recalibration. |
| Rail-to-rail input stage | Common-mode range includes VCC– - enables direct connection of ground-referenced transducers (e.g., strain gauges, thermocouples) without input bias networks. |
| High open-loop gain | 6.5 V/µV (136 dB) - maintains <0.001% gain error in 100× closed-loop configurations, critical for precision instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP27GP | Higher slew rate (2.8 V/µs) but wider offset spec (250 µV max), no phase-reversal protection, commercial temp only (0°C to +70°C). | Not qualified for military/aerospace use; unsuitable for systems requiring guaranteed operation below –40°C or above +85°C. | Select only for cost-sensitive commercial test equipment where extended temperature and phase-reversal immunity are not required. |
| LMC6062IMX | CMOS input (0.01 pA bias), rail-to-rail output, but lower bandwidth (1.4 MHz), higher noise (24 nV/√Hz), and no military temp rating. | Lacks phase-reversal protection and military qualification; better suited for ultra-high-impedance pH or ion-selective electrode sensors than harsh-environment transducers. | Choose for battery-powered portable instruments needing femtoampere input bias, but avoid where ±15 V operation or –55°C startup is mandatory. |
Compared with OP27GP and LMC6062IMX, the TLE2022AMDR uniquely combines military-temperature operation, phase-reversal immunity, rail-to-rail input, and sub-150 µV offset - making it irreplaceable in certified avionics, missile guidance, and nuclear instrumentation where failure modes must be eliminated by design.

FAQ
What is the maximum operating temperature range for the TLE2022AMDR?
The TLE2022AMDR is characterized and guaranteed to operate continuously from –55°C to +125°C. This full military temperature range is validated per MIL-PRF-38535 requirements and includes all electrical specifications - such as 300 µV max input offset voltage and 700 µA max supply current - across the entire span without derating.
Does the TLE2022AMDR support single-supply operation?
Yes, the TLE2022AMDR is explicitly specified for 5 V single-supply operation, with common-mode input range from 0 V to 3.2 V and output swing from 0.7 V to 4.3 V (RL = 10 kΩ). Its phase-reversal protection remains active even when the negative input goes below ground, making it robust in unipolar sensor interface applications.
What packaging type is used for the TLE2022AMDR?
The TLE2022AMDR uses an 8-pin ceramic dual in-line package (CDIP) with JG designation. It is a hermetically sealed, through-hole package rated for 300°C soldering (60 seconds) and designed for high-reliability applications including defense electronics and space-qualified systems.
How does phase-reversal protection work in the TLE2022AMDR?
The TLE2022AMDR integrates internal circuitry that actively disables the input stage when either input falls below the negative supply rail, preventing the output from erroneously inverting polarity. This eliminates the need for external diode clamps in sensor front-ends and ensures deterministic behavior during power-up, fault conditions, or transducer overrange events.
Is the TLE2022AMDR pin-compatible with other TLE2022xM variants?
Yes, all TLE2022xM variants - including TLE2022AMDR, TLE2022BMJG, and TLE2022MFK - share identical pinouts for the 8-pin CDIP (JG) and 20-pin LCCC (FK) packages. The "AM" suffix denotes the 120 µV max offset grade, but electrical connectivity and physical layout are fully interchangeable within the same package type.
