Product details
Overview
TLE2022AID from Texas Instruments is a dual-channel, precision operational amplifier using the Excalibur bipolar process, 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, supports single- (5 V) and split-supply (±15 V) configurations, and features phase-reversal protection for robust low-level signal conditioning in instrumentation front-ends.
For engineers reviewing the TLE2022AID datasheet, TLE2022AID pinout, TLE2022AID application, or TLE2022AID equivalent, key selection criteria include its military-grade temperature range, rail-to-rail input capability (down to negative rail), low 700 µA max supply current per channel at ±15 V, and verified performance in precision transducer amplification and data acquisition systems.
Technical Context
The TLE2022AID employs Texas Instruments' Excalibur complementary bipolar process with isolated vertical PNP transistors, enabling significantly improved unity-gain bandwidth and slew rate over legacy OP21-class amplifiers while maintaining ultra-stable DC parameters. Its bias circuit architecture ensures minimal drift in offset voltage (0.006 µV/month) and supply current (≤60 µA variation over full temperature range).
This dual op-amp integrates phase-reversal protection to prevent output inversion when inputs fall below the negative supply rail - a critical feature for single-supply sensor interfaces. Its common-mode input voltage range includes the negative rail (–15 V at ±15 V supply), supporting ground-referenced signal sources without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables matched-pair signal processing in differential receivers or dual-stage filtering without inter-device mismatch. |
| Unity-gain bandwidth | 2.8 MHz (typ, ±15 V) - supports stable closed-loop operation up to ~200 kHz in gain-of-10 configurations with adequate phase margin (52°). |
| Slew rate | 0.65 V/µs (typ, ±15 V) - allows faithful reproduction of 100 kHz sine waves at 1 V peak without slew-induced distortion. |
| Input offset voltage | 150 µV max (25°C, ±15 V) - ensures ≤1.5 mV error in 10 V full-scale 12-bit systems without trimming. |
| Supply current per channel | 700 µA max (±15 V, full temp range) - enables low-power operation in battery-backed analog front-ends or multi-channel DAQ modules. |
| Input bias current | 30 nA max (25°C, ±15 V) - minimizes voltage error across high-impedance sources (e.g., pH electrodes, piezoresistive sensors). |
| CMRR | 100 dB min (25°C, ±15 V) - rejects >100,000:1 of common-mode interference in noisy industrial environments. |
Pinout & Package
Package: 8-pin ceramic dual in-line package (CDIP), JG variant, hermetically sealed for military-temperature reliability (–55°C to +125°C). Pin 4 is VCC/GND (common power return), pin 8 is NC (no connect), and offset null pins (1 and 5) support external trimming.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Connects to external potentiometer wiper for manual input offset cancellation; required for sub-50 µV system-level accuracy. |
| 2 | Inverting Input (1IN–) | Primary input node for Channel 1; accepts signals down to –15 V (negative rail) with no phase reversal. |
| 3 | Non-inverting Input (1IN+) | Primary input node for Channel 1; supports rail-to-rail common-mode range including negative supply. |
| 4 | VCC / GND | Power return terminal - shared ground reference for both channels in single-supply mode or negative rail in split-supply mode. |
| 5 | Offset Null (N2) | Connects to external potentiometer end for Channel 1 offset adjustment; used with Pin 1 for symmetric nulling. |
| 6 | Output (1OUT) | Amplified output of Channel 1; drives ≥10 kΩ loads to ±13.9 V swing at ±15 V supply. |
| 7 | VCC+ | Positive supply terminal - accepts +5 V (single) or +15 V (split); internal regulation not required. |
| 8 | NC | No internal connection - must remain unconnected; no routing or grounding permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents output polarity flip when either input drops below VCC/GND, eliminating catastrophic errors in sensor monitoring circuits. |
| Rail-to-rail input (down to negative rail) | Enables direct interfacing with 0 V–referenced transducers (e.g., load cells, thermocouples) without input biasing networks. |
| Low long-term offset drift | 0.006 µV/month ensures <1 µV total drift over 10 years - critical for unattended field instrumentation calibration stability. |
| Military temperature qualification | Characterized from –55°C to +125°C with guaranteed parametric limits - suitable for avionics, downhole tools, and engine control units. |
| Low input noise voltage | 19 nV/√Hz at 10 Hz enables high-fidelity amplification of microvolt-level signals (e.g., ECG, strain gauge bridges) without dominant amplifier noise. |

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 voltage range (25 µV typ vs 150 µV max), no phase-reversal protection, commercial temp only (0°C to +70°C). | Not qualified for military-temperature or safety-critical phase-reversal scenarios; suited for lab-grade bench instruments. | Select OP27GP only if higher speed is mandatory and temperature range/phase safety are non-critical. |
| LMC6062IMX | CMOS input (0.01 pA bias current), rail-to-rail output, but lower bandwidth (1.4 MHz) and no military temp rating; offset drift 0.5 µV/°C vs TLE2022AID's 2 µV/°C. | Better for ultra-high-impedance photodiode or pH probe interfaces; unsuitable for high-temp or high-CMRR industrial use. | Choose LMC6062IMX for femtoampere-input applications where supply voltage is limited to 5 V and temperature stays within 0°C–70°C. |
Compared with OP27GP and LMC6062IMX, the TLE2022AID uniquely combines military-temperature operation, phase-reversal immunity, and bipolar precision-making it irreplaceable in avionics sensor signal chains and unattended field instrumentation where reliability trumps raw speed or ultra-low bias current.

FAQ
What is the maximum operating temperature range for the TLE2022AID?
The TLE2022AID is characterized for continuous operation from –55°C to +125°C, meeting MIL-STD-883 requirements for military-temperature applications. This full-range specification includes guaranteed limits for input offset voltage, supply current, and CMRR - unlike commercial-grade op-amps that only specify typical behavior at 25°C.
Does the TLE2022AID support single-supply operation?
Yes, the TLE2022AID is explicitly specified for 5 V single-supply operation per the datasheet's Recommended Operating Conditions and Electrical Characteristics tables. Its input common-mode range extends to the negative rail (0 V in single-supply mode), and output swings within 0.7 V of rails - enabling true ground-referenced signal handling without level-shifting circuitry.
How does phase-reversal protection work in the TLE2022AID?
The TLE2022AID incorporates internal circuitry that clamps input differential voltage and disables output stage inversion when either input falls below the negative supply rail (VCC/GND). This prevents the output from erroneously saturating positive when the inverting input is driven below ground - a failure mode that can corrupt feedback loops in sensor amplifiers and active filters.
Can the TLE2022AID drive heavy capacitive loads?
The TLE2022AID is not unity-gain stable into large capacitive loads; the datasheet specifies phase margin of 52° at unity gain with resistive loads only. Driving >100 pF directly may cause ringing or oscillation. For capacitive loads, add a series isolation resistor (≥200 Ω) between output and capacitance, or use a dedicated buffer stage.
Is pin 4 (VCC/GND) internally connected to substrate or case ground?
Pin 4 serves as the common power return terminal and is electrically tied to the IC's internal substrate reference. In single-supply operation, it functions as system ground; in split-supply operation, it connects to the negative rail. It must be bonded to the PCB ground plane with low-inductance layout - floating or capacitive coupling will degrade PSRR and introduce instability.
