Product details
Overview
TLE2024ACN 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 in ceramic DIP-14 packaging - ideal for military-grade sensor signal conditioning and low-level analog front-ends.
For engineers reviewing the TLE2024ACN datasheet, TLE2024ACN pinout, TLE2024ACN application, or TLE2024ACN equivalent, key selection criteria 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 under extended temperature cycling without parameter degradation.
Technical Context
The TLE2024ACN employs Texas Instruments' Excalibur complementary bipolar process with isolated vertical PNP transistors, enabling higher slew rate and unity-gain bandwidth than legacy OP21-based designs. Its bias circuit ensures exceptional stability of DC parameters over time and temperature - critical for long-life instrumentation systems.
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 (–15 V at ±15 V supply), making it suitable for single-supply interfacing with grounded sensors and transducers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-stage filtering, differential amplification, or independent channel processing in space-constrained military/aerospace PCBs. |
| Unity-gain bandwidth | 2.8 MHz at ±15 V - supports stable closed-loop operation up to ~200 kHz for gain ≥10, suitable for anti-aliasing and active filter design. |
| Slew rate | 0.7 V/µs at ±15 V - enables faithful reproduction of signals with <100 kHz full-power bandwidth and minimal distortion in precision DAC output buffers. |
| Input offset voltage | 1000 µV max at 25°C (TLE2024A grade) - defines worst-case DC error in high-gain sensor amplifiers; lower than standard TLE2024M (1300 µV). |
| Supply current per channel | 350 µA typical at ±15 V - total 1.4 mA quiescent draw enables low-power 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; lower than LM324 (35 nV/√Hz) and comparable to OPA277. |
| Operating temperature | –55°C to +125°C - qualified for MIL-PRF-38535 Class B applications; no derating required across full range for specified electrical performance. |

| 4 | Positive Supply (VCC+) | Connects to +15 V (or +5 V); shared across all four amplifiers; decoupling capacitor required near pin. |
| 5 | Channel 2 Non-inverting Input | Input for second amplifier; electrically isolated from other channels; supports same rail-to-rail CMVR as Pin 2/3. |
| 6 | Channel 2 Inverting Input | Inverting input for second op-amp; identical electrical specs and protection as Pin 2. |
| 7 | Channel 2 Output | Output of second amplifier; fully independent; no crosstalk specified beyond typical 100 dB PSRR. |

| 9 | Channel 3 Inverting Input | Third op-amp inverting input; supports same input bias current (max 50 nA) and offset voltage specs as other channels. |
| 10 | Ground / Negative Supply (VCC–) | Return path for ±15 V operation or ground reference for 5 V single-supply; must be low-impedance and star-connected. |
| 11 | Channel 4 Non-inverting Input | Fourth amplifier non-inverting input; enables simultaneous multi-sensor monitoring with matched DC performance. |
| 12 | Channel 4 Inverting Input | Fourth op-amp inverting input; shares same 2 µV/°C offset drift and 0.005 µV/month long-term stability. |
| 13 | Channel 4 Output | Final amplifier output; rated for same output voltage swing and load drive as Pins 1, 7, and 8. |
| 14 | Not Connected (NC) | No internal connection; left unconnected per TI recommendation to avoid parasitic coupling or mechanical stress on die bond wires. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4134UA | FET-input (vs bipolar), 8 MHz GBW, 20 V/µs slew, but 10× higher input capacitance (10 pF) and no phase-reversal protection. | Better for high-Z sources and audio; unsuitable for rail-to-rail input or negative-rail sensor interfaces without external clamping. | Select TLE2024ACN when negative-rail input, phase-reversal immunity, or military temp range are mandatory. |
| LMC6084IMX | CMOS-input, rail-to-rail I/O, 1.4 MHz GBW, 0.6 V/µs slew, 0.02 µV/°C drift - superior DC stability but lower speed and no military qualification. | Ideal for low-power, room-temp medical sensors; lacks hermetic packaging and extended temperature validation. | Choose TLE2024ACN for aerospace/military deployments where MIL-STD-883 screening and –55°C startup are required. |
Compared with OPA4134UA and LMC6084IMX, the TLE2024ACN uniquely combines military-grade temperature operation, phase-reversal immunity, and bipolar precision - making it irreplaceable in safety-critical analog signal chains where input fault behavior and long-term calibration integrity are non-negotiable.

FAQ
What is the maximum supply voltage rating for the TLE2024ACN?
The TLE2024ACN has absolute maximum supply voltage ratings of +20 V on VCC+ and –20 V on VCC–, per TI SLOS191E datasheet Section 5.1. Recommended operating range is ±2 V to ±20 V, with full specification guaranteed from ±15 V and 5 V single-supply. Exceeding ±20 V risks permanent damage to the Excalibur bipolar die.
Does the TLE2024ACN support true rail-to-rail input operation?
Yes - the TLE2024ACN's common-mode input voltage range extends to the negative supply rail (e.g., –15 V at ±15 V supply), enabling direct connection to grounded sensors. However, the positive input limit is 13.2 V (not +15 V), so it is not rail-to-rail on the positive side. This asymmetric CMVR is confirmed in Section 5.3 and Table 5.14 of the datasheet.
What is the guaranteed input offset voltage for the TLE2024ACN at 25°C?
The TLE2024ACN ('A' grade) guarantees a maximum input offset voltage of 1000 µV at 25°C under ±15 V supply, per Table 5.14 Electrical Characteristics. This is tighter than the standard TLE2024M grade (1300 µV max) and reflects tighter factory binning for precision applications.
Is the TLE2024ACN pin-compatible with other TLE2024 variants in CDIP-14?
Yes - all TLE2024xM variants (TLE2024M, TLE2024AM, TLE2024BM) use identical CDIP-14 pinout per Figure 4-6. Pin assignments for inputs, outputs, supplies, and NC are functionally and physically identical, allowing drop-in replacement within the same grade family without PCB changes.
How does the TLE2024ACN handle input overvoltage conditions below the negative supply rail?
The TLE2024ACN incorporates integrated phase-reversal protection circuitry that prevents output polarity inversion when either input falls below the negative supply rail - a known failure mode in many bipolar op-amps. This eliminates the need for external Schottky clamps and improves system robustness in noisy or fault-prone sensor environments.
