Product details
Overview
TLE2024ACDW from Texas Instruments is a quad-channel, precision operational amplifier using the Excalibur bipolar process, 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 in rugged instrumentation.
For engineers reviewing the TLE2024ACDW datasheet, TLE2024ACDW pinout, TLE2024ACDW application, or TLE2024ACDW 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 guaranteed performance over full military temperature range - critical for high-reliability analog front-ends.
Technical Context
The TLE2024ACDW employs Texas Instruments' Excalibur complementary bipolar process with isolated vertical PNP transistors, enabling enhanced unity-gain bandwidth and slew rate versus legacy precision op-amps like the OP21. Its bias circuit ensures exceptional parameter stability across time and temperature.
It features phase-reversal protection that prevents output inversion when inputs fall below the negative supply rail, and its common-mode input voltage range extends to the negative rail - enabling true single-supply operation and accurate low-level signal amplification in grounded-sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-stage filtering or simultaneous signal conditioning of four sensor channels without board space penalty. |
| Unity-gain bandwidth | 2.8 MHz at ±15 V - supports stable closed-loop gain ≥10 up to ~250 kHz with adequate phase margin (52°). |
| Slew rate | 0.7 V/µs at ±15 V - allows faithful reproduction of 110 kHz full-scale sine waves without distortion. |
| Input offset voltage | 1000 µV max at 25°C (TLE2024M grade) - defines worst-case DC error in precision gain stages; 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 systems. |
| Input noise voltage | 19 nV/√Hz at 10 Hz - sets fundamental SNR floor for sub-mV signal amplification in low-frequency sensor interfaces. |
| Common-mode input range | Includes negative rail (–15 V to +13.2 V at ±15 V) - permits direct interfacing with ground-referenced transducers without level-shifting. |

|---|---|---|---|
| OP297GPZ | Single-channel, 500 µV max VIO, 0.15 V/µs slew rate, 500 kHz GBW, SOIC-8 package | Lacks quad integration and military temp rating; lower speed limits use in >100 kHz signal paths | Select when board space is constrained and only one channel is needed; not suitable for multi-sensor systems or extended temperature environments. |
| LT1014DN#PBF | Quad-channel, 150 µV max VIO, 0.4 V/µs slew rate, 1.2 MHz GBW, PDIP-14 package | Lower offset and noise but slower response; not characterized beyond +85°C | Choose for ultra-low-offset requirements in commercial-temperature applications where bandwidth <1 MHz suffices. |

FAQ
What is the maximum operating temperature range for the TLE2024ACDW?
The TLE2024ACDW is characterized for continuous operation from –55°C to +125°C, meeting MIL-STD-883 temperature requirements. This full military range is explicitly confirmed in the device comparison tables and absolute maximum ratings section of the TI datasheet SLOS191E, making it suitable for extreme-environment applications such as avionics and downhole tools where commercial-grade op-amps would fail.
Does the TLE2024ACDW support single-supply operation?
Yes, the TLE2024ACDW is fully specified for 5 V single-supply operation per Section 5.12 of the datasheet, with common-mode input voltage range extending to the negative rail (0 V) and output swing within 0.8 V of rails. Its phase-reversal protection and rail-to-rail input stage eliminate the need for external level-shifting circuitry in grounded-sensor applications.
What is the typical input offset voltage drift over time for the TLE2024ACDW?
The TLE2024ACDW exhibits a typical input offset voltage long-term drift of 0.006 µV/month, as documented in Sections 5.14 and 5.6 of the TI datasheet. This value is derived from accelerated life testing at 150°C and extrapolated to 25°C using the Arrhenius model - ensuring predictable calibration stability over multi-year deployments in unattended instrumentation.
How does the TLE2024ACDW's phase-reversal protection function?
The TLE2024ACDW 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. As described in the "Description" section, this eliminates unexpected state changes during input transients, removing the need for external clamping diodes in sensor interfaces with grounded or negative-going signals.
Is the TLE2024ACDW pin-compatible with other TLE2024 variants?
Yes, the TLE2024ACDW (14-pin CDIP, J package) shares identical pinout with all TLE2024xM variants in the same package, including TLE2024M, TLE2024AM, and TLE2024BM, as confirmed by Figure 4-6 in the datasheet. Pin assignments for all four channels, supplies, and terminals are fixed and consistent across the J-package family.
