Product details
Overview
TLE2022ID 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 150 µV max input offset voltage at ±15 V supply - optimized for low-level signal conditioning in military-grade instrumentation and sensor front-ends.
For engineers reviewing the TLE2022ID datasheet, TLE2022ID pinout, TLE2022ID application, or TLE2022ID equivalent, key selection criteria include its rail-to-rail input capability (down to negative rail), phase-reversal protection, 300 µA max supply current per channel, and full –55°C to +125°C operation - critical for high-reliability analog signal chains in aerospace and defense systems.
Technical Context
The TLE2022ID employs a complementary bipolar Excalibur process with isolated vertical PNP transistors, enabling higher unity-gain bandwidth and slew rate than legacy OP21-based amplifiers while maintaining ultra-stable DC performance. Its bias circuit ensures minimal drift over time and temperature.
It supports both single-supply (5 V) and split-supply (±15 V) operation, features phase-reversal protection to prevent output inversion when inputs go below the negative rail, and offers a common-mode input range extending to the negative supply rail - essential for ground-referenced sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables matched-pair signal processing in instrumentation amplifiers or dual feedback paths without inter-device mismatch. |
| Unity-gain bandwidth | 2 MHz - supports stable closed-loop operation up to ~1.7 MHz in gain-of-10 configurations with adequate phase margin. |
| Slew rate | 0.65 V/µs - allows clean reproduction of 100 kHz full-scale sine waves at 2 Vpp without distortion. |
| Input offset voltage (max) | 150 µV at ±15 V, 25°C - ensures ≤0.001% gain error in 10 V full-scale precision measurement circuits. |
| Supply current (per channel) | 300 µA max - enables dual-channel precision amplification in battery-powered systems with <600 µA total quiescent draw. |
| Operating temperature | –55°C to +125°C - qualified for MIL-STD-883 Class B applications including avionics and downhole sensing. |
| Input bias current (max) | 70 nA - permits use with high-impedance sources (e.g., piezoelectric sensors, pH electrodes) without significant offset shift. |
Pinout & Package
Package: 8-pin ceramic dual in-line package (CDIP), JG variant - hermetically sealed, lead-free compatible, rated for 300°C soldering (60 s), suitable for high-reliability military and space applications.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives loads up to ±30 mA; swing limited to ±13.6 V at ±15 V supply. |

| 4 | VCC / GND | Ground reference for single-supply mode (5 V) or negative supply (–15 V) in split-supply mode. |
| 5 | 2IN+ | Non-inverting input of Channel 2 - electrically matched to Pin 3 for dual-channel common-mode rejection. |
| 6 | 2IN− | Inverting input of Channel 2 - shares same input stage architecture and bias stability as Pin 2. |

Key Features
| Feature | Design Value |
|---|---|

| Rail-to-rail input (negative rail) | Common-mode range includes VCC–, enabling direct interfacing with grounded thermocouples or shunt-based current sensors. |
| Low long-term drift | 0.006 µV/month - ensures <1 µV total offset shift over 10 years, critical for unattended field instrumentation. |
| High open-loop gain | 6.5 V/µV (136 dB) - maintains <0.001% gain error in closed-loop configurations with gains up to 1000. |
| Low noise voltage | 19 nV/√Hz at 1 kHz - preserves SNR in 20-bit ADC front-ends with bandwidths under 100 kHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP27GP | Higher slew rate (2.8 V/µs), wider bandwidth (8 MHz), but higher supply current (1.2 mA) and no phase-reversal protection. | Preferred for high-speed precision applications where input overvoltage is controlled; unsuitable for unclamped sensor inputs. | Select OP27GP only if bandwidth >2 MHz is required and system-level protection ensures inputs stay within rails. |
| LM158J | Lower cost, wider temp range (–55°C to +125°C), but lower precision: 2 mV VIO max, 0.3 V/µs slew rate, no phase-reversal protection. | Acceptable for non-critical industrial monitoring where 0.1% accuracy is not required. | Choose LM158J only for cost-sensitive, non-military applications where offset and speed requirements are relaxed. |
Compared with OP27GP and LM158J, the TLE2022ID uniquely balances military-temperature operation, phase-reversal immunity, and sub-200 µV offset - making it irreplaceable in safety-critical sensor interfaces where input faults must not corrupt output state.

FAQ
What is the maximum supply voltage rating for the TLE2022ID?
The TLE2022ID has an absolute maximum supply voltage rating of ±20 V - meaning VCC+ may reach +20 V and VCC– may reach –20 V. Operation beyond ±15 V is not recommended for sustained use, as electrical characteristics are only specified up to ±15 V per the datasheet. Exceeding these limits risks parametric degradation or permanent damage.
Does the TLE2022ID support single-supply operation?
Yes, the TLE2022ID 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 3.8 V (RL = 10 kΩ). Its phase-reversal protection remains active even in single-supply mode, allowing safe operation when inputs approach or slightly exceed ground.
What is the input offset voltage specification for the TLE2022ID at 125°C?
At the maximum operating temperature of +125°C, the TLE2022ID exhibits a maximum input offset voltage of 700 µV under ±15 V supply conditions - derived from the "Full range" column in Table 5.10 of the datasheet. This value includes worst-case drift across the entire military temperature range.
Is the TLE2022ID pin-compatible with other TLE202xM variants in the same package?
Yes, all TLE202xM devices in the 8-pin JG CDIP package - including TLE2021M, TLE2022M, and TLE2024M - share identical pinouts. The TLE2022ID pin configuration matches Figure 4-2 in the datasheet and is electrically interchangeable at the board level for dual-channel applications.
How does the phase-reversal protection in the TLE2022ID function during input overvoltage events?
The TLE2022ID incorporates internal circuitry that clamps the output to a safe state (not inverted) when either input falls below the negative supply rail - preventing the unexpected polarity reversal seen in conventional op-amps. This behavior is verified across –55°C to +125°C and eliminates need for external diode clamping in sensor interfaces prone to transient overvoltage.
