Product details
Overview
TLE2022AMD from Texas Instruments is a dual-channel, precision operational amplifier using Excalibur bipolar process technology, delivering 2 MHz unity-gain bandwidth, 0.65 V/µs slew rate, and 100 µV max input offset voltage at ±15 V supply. It operates across –55°C to +125°C and supports both single-5V and split-±15V configurations, making it suitable for military-grade sensor signal conditioning and low-level analog front-ends.
For engineers reviewing the TLE2022AMD datasheet, TLE2022AMD pinout, TLE2022AMD application, or TLE2022AMD equivalent, key selection considerations include its phase-reversal protection, rail-to-rail input capability (down to negative rail), low 300 µA max supply current per channel, and stable dc performance over temperature and time-critical for high-reliability instrumentation and avionics interfaces.
Technical Context
The TLE2022AMD employs Texas Instruments' Excalibur complementary bipolar process with isolated vertical PNP transistors, enabling improved unity-gain bandwidth and slew rate versus legacy OP21-class amplifiers. Its bias circuit ensures minimal parameter drift: only 2 µV/°C offset tempco and 0.006 µV/month long-term drift.
It features phase-reversal protection that prevents output inversion when either input falls below the negative supply rail, and supports common-mode input voltage ranges extending to the negative rail (–15 V at ±15 V supply), enabling true single-supply operation in 5 V systems with VICR down to 0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables compact dual-path signal processing without cross-talk in matched-pair configurations. |
| 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 - allows faithful reproduction of 200 kHz full-scale sine waves at 1 Vpp without distortion. |
| Input offset voltage (max) | 150 µV at 25°C, ±15 V - ensures ≤1.5 mV error in 10 V full-scale measurement systems before trimming. |
| Supply current (max) | 700 µA total (350 µA/channel) at ±15 V - enables low-power operation in battery-backed or thermally constrained military modules. |
| Operating temperature | –55°C to +125°C - qualified for MIL-PRF-38535 Class B applications including airborne and ground vehicle control units. |
| Input bias current (max) | 70 nA at 25°C - permits use with high-impedance sources (e.g., piezoelectric sensors, pH electrodes) without significant offset error. |
Pinout & Package
Ceramic Dual-In-Line Package (CDIP), 8-pin, hermetically sealed, with metal lid and glass-sealed leads. Designed for high-reliability, high-temperature, and low-outgassing environments typical of aerospace and defense systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | Accepts differential input signal referenced to non-inverting input; phase-reversal protected. |
| 2 | Non-inverting input (Channel 1) | Supports common-mode range to negative rail; enables single-supply operation with ground-referenced inputs. |
| 3 | Output (Channel 1) | Capable of ±30 mA drive into resistive loads; output swing reaches ±13.9 V at ±15 V supply. |
| 4 | VCC / GND | Ground reference for single-supply mode (5 V); negative supply rail for split-supply operation (±15 V). |
| 5 | Non-inverting input (Channel 2) | Independent input stage with same rail-to-rail common-mode capability as Channel 1. |
| 6 | Inverting input (Channel 2) | Phase-reversal protected; electrically isolated from Channel 1 inputs per datasheet layout guidelines. |
| 7 | Output (Channel 2) | Matched dynamic performance to Channel 1; supports independent gain-setting networks. |
| 8 | VCC+ | Positive supply rail (5 V or +15 V); decoupling required within 1 cm for stability at full bandwidth. |
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 ruggedized designs. |
| Rail-to-rail input (to negative rail) | Enables direct interfacing with 0 V–referenced transducers (e.g., strain gauges, thermocouples) without level-shifting circuitry. |
| Low long-term drift (0.006 µV/month) | Reduces calibration frequency in field-deployed test equipment; supports >10-year unadjusted accuracy in sealed enclosures. |
| High open-loop gain (6.5 V/µV) | Ensures <0.001% gain error in unity-gain buffers and <0.01% error in 100× inverting amplifiers at dc and low frequencies. |
| Military temperature qualification | Tested and screened per MIL-PRF-38535 requirements, including burn-in, thermal cycling, and hermeticity verification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP27GM | Higher slew rate (2.8 V/µs) but wider offset spec (25 µV typ, 75 µV max); no phase-reversal protection; not rated beyond +85°C. | Preferred for high-speed precision applications where temperature range is limited to commercial/industrial. | Select OP27GM only if phase-reversal immunity and extended temperature are not required; verify PCB layout for higher bandwidth stability. |
| LT1013DM | Lower power (125 µA/ch), lower bandwidth (1.2 MHz), no phase-reversal protection; SOIC package only; qualified to –40°C to +85°C. | Suitable for cost-sensitive industrial DAQ where hermeticity and military temp range are unnecessary. | Choose LT1013DM for board space-constrained designs needing dual op-amps in plastic packages; avoid in safety-critical or wide-temp deployments. |
Compared with OP27GM and LT1013DM, the TLE2022AMD uniquely combines military temperature rating, phase-reversal immunity, and rail-to-rail input capability-making it irreplaceable in avionics sensor interfaces where input transients and thermal extremes coexist.

FAQ
What is the maximum supply voltage rating for the TLE2022AMD?
The TLE2022AMD has absolute maximum supply voltage ratings of +20 V on VCC+ and –20 V on VCC–, per TI SLOS191E datasheet Section 5.1. Recommended operating range is ±2 V to ±20 V. Operation at ±15 V is fully characterized and supported across the full military temperature range, with verified parameters including 0.65 V/µs slew rate and 2 MHz bandwidth.
Does the TLE2022AMD support single-supply operation?
Yes, the TLE2022AMD supports true single-supply operation at 5 V. Its common-mode input voltage range extends to the negative rail (0 V at 5 V supply), and output swings to within 0.7 V of each rail. The device is explicitly specified for both 5 V single-supply and ±15 V split-supply operation in the official datasheet, with full electrical characterization at both conditions.
What packaging options are available for the TLE2022AMD?
The TLE2022AMD is offered exclusively in the JG package: an 8-pin ceramic dual-in-line package (CDIP) with metal lid and glass-sealed leads. This hermetic package meets MIL-PRF-38535 requirements and is distinct from plastic SOIC or LCCC variants. No other package types (e.g., SOIC, TSSOP, LCCC) are designated for the "M" suffix military-grade version.
How does phase-reversal protection work in the TLE2022AMD?
The TLE2022AMD integrates internal circuitry that prevents output polarity inversion when either input drops below the negative supply rail-a failure mode common in standard op-amps. This eliminates the need for external Schottky clamping diodes in harsh environments where input transients (e.g., ESD, load dump) can drive pins negative. The protection is active across the full –55°C to +125°C range and does not degrade bandwidth or noise performance.
Is the TLE2022AMD pin-compatible with other TLE202xM variants?
Yes, all TLE202xM dual-amplifier variants-including TLE2022AM, TLE2022BM, and TLE2022M-share identical 8-pin JG CDIP pinouts and footprint. Differences lie solely in tested performance grades (e.g., VIO max = 120 µV for AM, 300 µV for M), not connectivity or layout. Designers may substitute across grades without PCB revision, provided system-level offset and drift budgets permit the selected grade.
