Product details
Overview
TLE2024CN 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 ±2 V to ±20 V supplies and features rail-to-rail common-mode input range including the negative rail, making it suitable for low-level signal conditioning in military-grade instrumentation and sensor front-ends.
For engineers reviewing the TLE2024CN datasheet, TLE2024CN pinout, TLE2024CN application, or TLE2024CN equivalent, key selection criteria include its 14-pin CDIP package with dual offset null pins per pair, phase-reversal protection, stable 2 µV/°C offset drift over –55°C to +125°C, and verified performance in single-supply (5 V) and split-supply (±15 V) configurations.
Technical Context
The TLE2024CN employs Texas Instruments' Excalibur complementary bipolar process with isolated vertical PNP transistors, enabling improved unity-gain bandwidth and slew rate versus legacy OP21-based designs. Its bias circuit ensures exceptional parameter stability across temperature and time.
It integrates phase-reversal protection to prevent output inversion when inputs fall below the negative supply rail, and supports operation with common-mode input voltage extending to the negative rail - critical for single-supply transducer interfacing and precision difference amplifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-stage filtering, simultaneous sensor channel processing, or independent gain stages without inter-chip propagation delay. |
| Unity-gain bandwidth | 2.8 MHz at ±15 V - supports stable closed-loop operation up to ~200 kHz for 10× gain, suitable for anti-aliasing and active filter design. |
| Slew rate | 0.7 V/µs at ±15 V - limits full-power bandwidth to ~112 kHz, sufficient for 12-bit DAC buffering and medium-speed data acquisition. |
| Input offset voltage | 1000 µV max at 25°C (TLE2024M grade) - defines minimum resolvable DC signal; lower grades (AM/BM) offer 750 µV/500 µV for higher precision. |
| Supply current per channel | 350 µA typical at ±15 V - total 1400 µA quiescent draw enables low-power precision operation in battery-backed systems. |
| Operating temperature | –55°C to +125°C - qualified for MIL-STD-883 Class B environments, including avionics, downhole tools, and defense electronics. |
| Input bias current | 50 nA max at 25°C - compatible with high-impedance sources (e.g., piezoelectric sensors, pH electrodes) without significant error. |
Pinout & Package
Package: 14-pin Ceramic Dual-In-Line Package (CDIP, J package), hermetically sealed, rated for 300°C soldering, suitable for high-reliability and extended-temperature applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 14 | Output (Channel 1 & 4) | Amplified output nodes; each capable of ±40 mA short-circuit current and ±13.7 V swing at ±15 V supply. |

| 3, 12 | Non-inverting input (Ch1 & Ch4) | High-impedance inputs (50 nA max bias); enable reference-based sensing and precision summing configurations. |
| 4 | Positive supply (VCC+) | Accepts +2 V to +20 V; shared across all four op-amps; requires local 0.1 µF ceramic decoupling. |
| 11 | Negative supply / GND (VCC–) | Accepts –2 V to –20 V or ground in single-supply mode; common return for all channels. |
| 5, 10 | Non-inverting input (Ch2 & Ch3) | Matched input structure to Pins 3/12; allows identical configuration across all four channels. |
| 6, 9 | Inverting input (Ch2 & Ch3) | Matched to Pins 2/13; supports interleaved or cascaded topologies without layout asymmetry. |
| 7, 8 | Output (Ch2 & Ch3) | Independent outputs; no internal crosstalk; each drives loads up to 10 kΩ with <0.1% gain error. |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents output latch-up or polarity inversion when either input drops below VCC–, eliminating need for external clamping diodes in transducer interfaces. |
| Rail-inclusive common-mode input | Allows direct connection of grounded-sensor outputs (e.g., thermocouples, strain gauges) without level-shifting circuitry. |
| Low long-term drift | 0.006 µV/month offset drift ensures calibration stability over multi-year deployments in test equipment and monitoring systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP297GPZ | Single-channel, 500 µV max VIO, 0.15 V/µs slew, 0.5 mA supply current - lower speed but superior DC precision and lower noise (11 nV/√Hz). | Best for ultra-low-drift, low-bandwidth applications (e.g., digital multimeters); not quad-channel or military-qualified. | Select when absolute DC accuracy outweighs channel count and temperature range requirements. |
| LM124J | Quad-channel, 3 mV max VIO, 0.5 V/µs slew, 1.4 mA supply current - wider availability but looser DC specs and no phase-reversal protection. | Suitable for commercial industrial controls where cost and stock availability dominate; lacks MIL-spec screening and rail-inclusive input. | Choose for non-military, cost-sensitive designs where 3 mV offset and absence of phase-reversal protection are acceptable. |
Compared with OP297GPZ and LM124J, the TLE2024CN uniquely balances quad-channel integration, military temperature range, phase-reversal immunity, and 2.8 MHz bandwidth - making it irreplaceable in space-constrained, high-reliability analog signal chains requiring both speed and precision.

FAQ
What is the maximum operating supply voltage for the TLE2024CN?
The TLE2024CN supports a maximum supply voltage of ±20 V (40 V total differential), with absolute maximum ratings specifying VCC+ ≤ +20 V and VCC– ≥ –20 V. Operation beyond these limits risks permanent damage. Recommended operating range is ±2 V to ±20 V, and the device maintains specified performance across this full span.
Does the TLE2024CN include offset null capability?
Yes, the TLE2024CN provides two dedicated offset null pins per amplifier pair: Pin 2 (OFFSET N1) and Pin 5 (OFFSET N2) on the 14-pin CDIP package. These allow external trimming of input offset voltage using a 10-kΩ potentiometer connected between them, with the wiper grounded - a feature critical for high-accuracy DC-coupled applications.
How does phase-reversal protection function in the TLE2024CN?
The TLE2024CN incorporates internal circuitry that prevents output polarity inversion when either input falls below the negative supply rail (VCC–). This eliminates the need for external diode clamps in grounded-sensor applications like thermocouples or bridge transducers, preserving signal integrity and reducing bill-of-materials complexity in precision front-ends.
Is the TLE2024CN pin-compatible with other TLE2024 variants?
Yes, the TLE2024CN shares identical pinout and footprint with all TLE2024xM variants (e.g., TLE2024AM, TLE2024BM, TLE2024M) in the 14-pin CDIP (J) package. Differences lie solely in tested specifications (e.g., offset voltage grade), not electrical or mechanical compatibility - enabling drop-in replacement within the same package family.
What is the typical input bias current of the TLE2024CN at 125°C?
The TLE2024CN exhibits a maximum input bias current of 90 nA across the full –55°C to +125°C range, with typical values remaining near 50 nA even at +125°C. This stability is enabled by the Excalibur process's isolated vertical PNP transistors, ensuring predictable high-impedance source interfacing in extreme-temperature deployments.
