Product details
Overview
TLE2024IN from Texas Instruments is a quad-channel, precision operational amplifier using Excalibur bipolar process technology, delivering 2.8 MHz unity-gain bandwidth, 0.7 V/µs slew rate (±15 V), and 1000 µV max input offset voltage at 25°C. It operates across –55°C to +125°C and supports both ±15 V and 5 V single-supply configurations, making it suitable for military-grade sensor signal conditioning and low-level analog front-ends.
For engineers reviewing the TLE2024IN datasheet, TLE2024IN pinout, TLE2024IN application, or TLE2024IN equivalent, key selection considerations include its rail-to-rail input capability (includes negative rail), phase-reversal protection, low 19 nV/√Hz input noise, stable 2 µV/°C offset drift, and verified performance in high-reliability instrumentation and data acquisition systems.
Technical Context
The TLE2024IN employs Texas Instruments' Excalibur complementary bipolar process with isolated vertical PNP transistors, enabling improved unity-gain bandwidth and slew rate over legacy OP21-based designs. Its bias circuit ensures exceptional parameter stability over time and temperature.
It features phase-reversal protection that prevents output inversion when inputs fall below the negative supply rail, and supports common-mode input voltage ranges extending to the negative rail - critical for single-supply low-side sensing and precision difference amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-stage filtering, simultaneous signal conditioning of four sensors, or independent gain stages in one package. |
| Unity-gain bandwidth | 2.8 MHz at ±15 V - supports stable closed-loop operation up to ~200 kHz in gain-of-10 configurations with adequate phase margin. |
| Slew rate | 0.7 V/µs at ±15 V - allows faithful reproduction of signals up to ~110 kHz full-scale sine wave without slew-induced distortion. |
| Input offset voltage | 1000 µV max at 25°C (TLE2024M grade) - defines minimum resolvable DC signal in precision amplification; long-term drift ≤0.006 µV/month. |
| Supply current per channel | 350 µA typical at ±15 V - total 1400 µA quiescent draw enables low-power precision operation in battery-backed or thermally constrained systems. |
| Input noise voltage | 19 nV/√Hz at 1 kHz - sets fundamental SNR floor for sub-mV signal amplification in sensor interfaces and medical front-ends. |
| Operating temperature | –55°C to +125°C - qualified for extended-range military, aerospace, and downhole industrial applications without derating. |
Pinout & Package
Package: 14-pin ceramic dual in-line package (CDIP), hermetically sealed, rated for high-reliability military environments. Pin 11 is VCC / GND (common power return), Pin 4 is VCC+, and all four op-amp sections share this dual-supply topology.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 7, 14 | Output (OUT) | Amplified output terminals for channels 1–4 respectively; capable of ±40 mA short-circuit current. |
| 2, 6, 9, 13 | Inverting input (IN−) | Differential input nodes with 50 nA max input bias current; support rail-to-rail common-mode range including negative rail. |
| 3, 10, 12, 4 | Non-inverting input (IN+) | High-impedance inputs with phase-reversal protection; enable robust single-supply operation without external clamping. |
| 4 | VCC+ | Positive supply terminal; absolute max rating ±20 V; requires local decoupling for stability at high frequencies. |
| 11 | VCC / GND | Common return path for both supplies; must be low-impedance to minimize crosstalk between channels. |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents output latch-up or polarity inversion when IN− or IN+ drops below VCC−, eliminating need for external input clamping diodes. |
| Rail-to-rail input common-mode range | Includes negative supply rail (VICR = –15 V to +13.2 V at ±15 V), enabling direct interface with ground-referenced transducers and low-side current shunts. |
| Low long-term offset drift | 0.006 µV/month typical - ensures calibration stability over years in unattended monitoring systems and test equipment. |
| Excalibur process isolation | Vertical PNP transistors reduce parasitic capacitance and improve bandwidth/slew rate vs conventional bipolar processes, without sacrificing DC precision. |
| Military temperature qualification | Characterized and tested across –55°C to +125°C per MIL-PRF-38535, supporting Class B or Class S screening for space and defense programs. |

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), lower noise (3.5 nV/√Hz), but only dual-channel and not qualified beyond 85°C. | Not suitable for extended temperature or quad-channel density requirements; lacks phase-reversal protection. | Select OP27GP only for commercial-grade, high-speed, low-noise applications where military temp range and input protection are unnecessary. |
| LMC6084IM | CMOS input (0.01 pA bias), rail-to-rail output, but lower bandwidth (1.3 MHz) and higher offset drift (3 µV/°C). | Better for ultra-low-input-current pH or photodiode amps; unsuitable for high-precision, wide-temp DC stability needs. | Choose LMC6084IM when input bias current dominates error budget, but avoid where long-term offset stability or high slew rate is required. |
Compared with OP27GP and LMC6084IM, the TLE2024IN uniquely balances military-grade temperature operation, quad-channel integration, phase-reversal immunity, and sub-20 nV/√Hz noise - making it irreplaceable in high-reliability analog signal chains where all four attributes are simultaneously mandatory.

FAQ
What is the maximum operating temperature range for the TLE2024IN?
The TLE2024IN is characterized and tested across –55°C to +125°C per MIL-PRF-38535 requirements, making it suitable for deployment in engine compartments, downhole tools, and airborne electronics where ambient extremes exceed commercial-grade limits. This full military temperature range is guaranteed for all electrical parameters in the datasheet, including offset voltage, CMRR, and slew rate.
Does the TLE2024IN support single-supply operation?
Yes, the TLE2024IN is explicitly specified for 5 V single-supply operation per Section 5.12 of the datasheet. Its common-mode input voltage range extends to the negative rail (0 V in single-supply mode), and phase-reversal protection ensures safe operation even if inputs dip below ground - enabling robust interfacing with ground-referenced sensors without external level-shifting circuitry.
What is the input offset voltage specification for the TLE2024IN at room temperature?
The TLE2024IN (M-suffix) has a maximum input offset voltage of 1000 µV at 25°C under ±15 V supply conditions, as specified in Table 5.14. This value increases to 1200 µV across the full –55°C to +125°C range. The device also exhibits low long-term drift of 0.006 µV/month, ensuring calibration integrity in long-duration deployments.
How does the TLE2024IN's phase-reversal protection function?
The TLE2024IN integrates internal circuitry that prevents output polarity inversion when either input falls below the negative supply rail - a failure mode common in standard op-amps during input overvoltage or ESD events. This eliminates the need for external Schottky clamping diodes in sensitive front-ends, reducing BOM count and preserving signal integrity in military and aerospace sensor interfaces.
Is the TLE2024IN pin-compatible with other quad op-amps in the same package?
No - the TLE2024IN uses a proprietary 14-pin CDIP pinout optimized for its Excalibur process and phase-reversal architecture, differing from industry-standard quad op-amp layouts (e.g., LM324, TL084). Pin mapping must be verified against Figure 4-6 in the datasheet; direct replacement requires PCB redesign unless using identical TLE2024xM variants (e.g., TLE2024AMJ or TLE2024BMJ).
