Product details
Overview
TLE2022AIP 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 150 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 TLE2022AIP datasheet, TLE2022AIP pinout, TLE2022AIP application, or TLE2022AIP equivalent, key selection criteria include military-temperature stability, rail-to-rail input capability (down to negative rail), low 700 µA max supply current per channel, and verified performance in precision transducer amplification, active filtering, and data acquisition systems requiring long-term dc accuracy.
Technical Context
The TLE2022AIP employs Texas Instruments' Excalibur complementary bipolar process with isolated vertical PNP transistors, enabling higher unity-gain bandwidth and slew rate than legacy OP21-based designs while maintaining ultra-low drift. Its bias circuit architecture ensures stable parameters over time and temperature-critical for systems where calibration intervals exceed years.
Phase-reversal protection actively prevents output polarity inversion when either input falls below the negative supply rail, eliminating latch-up risk in sensor interfaces with transient overvoltage or power sequencing mismatches. The device's common-mode input range includes the negative rail under both 5 V and ±15 V operation, supporting true single-supply sensor signal conditioning without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual amplifier - enables matched-pair signal paths in differential receivers or dual-stage filters without inter-device mismatch. |
| Unity-gain bandwidth | 2 MHz - supports stable closed-loop operation up to ~1.7 MHz in gain-of-1 configurations with ≥42° phase margin. |
| Slew rate | 0.65 V/µs - delivers <1 µs settling to 0.1% for 1 V step inputs, suitable for medium-speed data acquisition sampling. |
| Input offset voltage (max) | 150 µV at ±15 V, 25°C - contributes ≤0.001% error in 10 V full-scale measurement systems before trimming. |
| Supply current (max) | 700 µA per channel at ±15 V - enables low-power operation in battery-backed or thermally constrained military/aerospace modules. |
| Operating temperature | –55°C to +125°C - qualified for extended-life deployment in engine control units, downhole sensors, and avionics power supplies. |
| Input bias current (max) | 70 nA at ±15 V - allows 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), hermetically sealed, rated for military-temperature operation and high-reliability environments.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Connects to external potentiometer for manual input offset trimming; required for sub-50 µV system-level offset targets. |
| 2 | Inverting Input (1IN–) | Primary inverting input of Channel 1; accepts signals referenced to negative rail due to rail-inclusive common-mode range. |
| 3 | Non-inverting Input (1IN+) | Primary non-inverting input of Channel 1; supports direct connection to grounded or negative-referenced sensors. |
| 4 | VCC / GND | Ground pin for single-supply (5 V) operation; connects to system ground-no separate negative supply needed in 5 V mode. |
| 5 | Non-inverting Input (2IN+) | Non-inverting input of Channel 2; electrically isolated from Channel 1 inputs to prevent crosstalk in dual-path designs. |
| 6 | Inverting Input (2IN–) | Inverting input of Channel 2; shares same rail-inclusive input range as Pin 2, enabling matched dual-sensor interfaces. |
| 7 | Output (2OUT) | Amplified output of Channel 2; capable of ±13.6 V swing into 10 kΩ load at ±15 V supply, supporting analog output stages. |
| 8 | VCC+ | Positive supply pin - accepts +5 V (single) or +15 V (split); internal regulation ensures stable biasing across full temperature range. |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents output polarity flip when inputs go below VCC–, eliminating need for external clamping diodes in sensor front-ends. |
| Rail-inclusive common-mode input range | Supports VIC down to VCC– (–15 V or 0 V), enabling direct interfacing with grounded thermocouples or shunt-based current sensors. |
| Low long-term drift | 0.006 µV/month - ensures <1 µV total offset drift over 5 years, critical for unattended monitoring systems. |
| High open-loop gain | 4 V/µV (132 dB) min at ±15 V - maintains <0.001% gain error in closed-loop gains up to 1000 with adequate loop margin. |
| Military-grade temperature qualification | Characterized and tested across –55°C to +125°C - eliminates derating calculations for aerospace or defense thermal profiles. |

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 (250 µV max), no phase-reversal protection, commercial temp only (0°C to +70°C). | Lacks military-temperature support and rail-inclusive input range-unsuitable for downhole or avionics deployments. | Select when speed > precision and temperature range is limited to benign environments. |
| LM158J | Lower cost, lower bandwidth (1 MHz), higher offset (3 mV max), no phase-reversal protection, same JG package but not qualified to –55°C. | Not characterized for long-term drift or high-PSRR operation-limited to non-critical industrial controls. | Select only for cost-sensitive, non-mission-critical applications where 150 µV offset and 125°C operation are unnecessary. |
Compared with OP27GP and LM158J, the TLE2022AIP uniquely combines military-temperature operation, phase-reversal immunity, rail-inclusive input, and sub-200 µV offset-making it the sole choice for high-reliability analog signal chains where parameter stability over decades and extreme environments is non-negotiable.

FAQ
What is the maximum supply voltage rating for TLE2022AIP?
The TLE2022AIP has an absolute maximum supply voltage rating of ±20 V across VCC+ and VCC– pins. Operation beyond ±15 V is not recommended for sustained use, as electrical characteristics-including offset voltage, CMRR, and slew rate-are only specified and guaranteed within the ±2 V to ±20 V recommended operating range, with full characterization at ±15 V. Exceeding ±20 V risks permanent damage.
Does TLE2022AIP support single-supply operation at 5 V?
Yes, the TLE2022AIP is fully specified for 5 V single-supply operation with VCC+ = 5 V and VCC / GND = 0 V. In this configuration, its common-mode input range extends from 0 V to 3.2 V, and output swing reaches 0.7 V to 3.8 V into a 10 kΩ load-enabling direct interface with 3.3 V ADCs and microcontrollers without level-shifting circuitry.
How does phase-reversal protection work in TLE2022AIP?
TLE2022AIP incorporates internal circuitry that detects when either input falls below the negative supply rail and actively disables the input stage to prevent output polarity inversion. This eliminates the need for external Schottky clamps in sensor interfaces subject to transients or power sequencing faults-preserving system integrity without adding board space or BOM cost.
What is the long-term input offset voltage drift specification for TLE2022AIP?
The TLE2022AIP exhibits a typical long-term input offset voltage drift of 0.006 µV per month at 25°C, extrapolated from accelerated life testing. Over 10 years of continuous operation, this equates to <0.7 µV total drift-well within the 150 µV initial max spec-making it suitable for uncalibrated, maintenance-free field deployments in remote monitoring systems.
Is TLE2022AIP pin-compatible with other TLE2022xM variants in the same package?
Yes, all TLE2022xM devices-including TLE2022AM, TLE2022BM, and TLE2022M-in the 8-pin CDIP (JG) package share identical pinout, footprint, and soldering profile. Differences are limited to internal trimming (affecting VIO, CMRR, and kSVR), so PCBs designed for any TLE2022xM JG variant can accept TLE2022AIP without layout changes.
