Product details
Overview
TLE2024CDWR 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, supports ±15 V and 5 V single-supply configurations, and features phase-reversal protection for robust low-level signal conditioning in military-grade instrumentation.
For engineers reviewing the TLE2024CDWR datasheet, TLE2024CDWR pinout, TLE2024CDWR application, or TLE2024CDWR equivalent, key selection criteria include its rail-to-rail-compatible common-mode input range (down to negative rail), low 1.4 mA total supply current (±15 V), 19 nV/√Hz input voltage noise, and verified performance in high-stability analog front-ends requiring long-term dc precision.
Technical Context
The TLE2024CDWR employs Texas Instruments' Excalibur complementary bipolar process with isolated vertical PNP transistors, enabling enhanced unity-gain bandwidth and slew rate over legacy precision op-amps like the OP21. Its bias circuit ensures stable parameters across temperature and time-critical for systems where offset drift must remain ≤2 µV/°C and ≤0.006 µV/month.
Designed for dual- and single-supply operation, it features a common-mode input voltage range extending to the negative rail and phase-reversal protection that prevents output inversion when inputs go below VCC–. These traits make it suitable for sensor interfaces and precision difference amplifiers where input signals may approach or exceed supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-stage filtering, simultaneous sensor channel conditioning, or independent feedback loops in one package. |
| Unity-gain bandwidth | 2.8 MHz (±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 (±15 V, typ) - allows faithful reproduction of 110 kHz full-scale sine waves without slewing distortion. |
| Input offset voltage | 1000 µV max (±15 V, 25°C) - defines worst-case initial error in precision dc-coupled gain stages; trimmed variants (e.g., TLE2024AM) offer 500 µV max. |
| Supply current per channel | 350 µA (±15 V, typ) - yields 1.4 mA total quiescent current, enabling low-power precision in battery-backed or thermally constrained systems. |
| Input voltage noise | 19 nV/√Hz (±15 V, 1 kHz) - sets fundamental noise floor for low-frequency sensor amplification; lower than standard JFET-input op-amps in same class. |
| Operating temperature | –55°C to +125°C - qualified for extended-range military, aerospace, and downhole industrial applications without derating. |
Pinout & Package
Package: 14-pin CDIP (J package), hermetically sealed ceramic dual in-line, rated for high-reliability military environments. Pin 11 is VCC / GND (common power terminal shared across all four amplifiers); pin 4 is dedicated VCC+.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 output | Low-impedance buffered output node; capable of ±40 mA short-circuit current. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA227P | Higher precision (75 µV VIO max), JFET input (50 pA IIB), but only dual-channel and not military-temperature rated. | Preferred for lab-grade instrumentation where ultra-low bias current and offset dominate; unsuitable for extended-temperature embedded deployments. | Select OPA227P only when sub-100 µV offset and femtoampere bias are mandatory-and ambient temperature stays within 0°C to +70°C. |
| LM124J | Quad architecture, same CDIP-14 package, but older bipolar process: 3 MHz GBW, 0.5 V/µs SR, 3000 µV VIO max, no phase-reversal protection. | Acceptable for cost-sensitive, non-critical analog functions where rail-to-rail input and long-term stability are not required. | Choose LM124J only for legacy redesigns with fixed layout; avoid where input signals approach supply rails or long-term calibration integrity is essential. |
Compared with OPA227P and LM124J, the TLE2024CDWR uniquely balances military-temperature operation, phase-reversal immunity, and quad-channel integration-making it the sole option among these three for new designs requiring guaranteed performance from –55°C to +125°C with rail-inclusive input handling.

FAQ
What is the maximum supply voltage rating for the TLE2024CDWR?
The TLE2024CDWR has an absolute maximum supply voltage rating of ±20 V across VCC+ and VCC– terminals. Operation beyond this limit-even momentarily-may cause permanent damage. Recommended operating range is ±2 V to ±20 V, with full electrical specifications guaranteed from ±15 V and 5 V single-supply configurations.
Does the TLE2024CDWR support true single-supply operation with input signals at ground potential?
Yes, the TLE2024CDWR supports true single-supply operation: its common-mode input voltage range extends to the negative rail (0 V when GND is used as VCC–), allowing inputs at ground level without phase reversal or clipping. This is enabled by its proprietary input stage design and phase-reversal protection circuitry.
How does the TLE2024CDWR's input offset voltage compare to the TLE2024AM variant?
The TLE2024CDWR has a maximum input offset voltage of 1000 µV at 25°C under ±15 V supply, while the TLE2024AM variant is specified at 500 µV max under identical conditions. Both share the same 2 µV/°C temperature coefficient and 0.006 µV/month long-term drift, making the AM grade preferable where tighter initial dc accuracy is required.
Can the TLE2024CDWR be used in unity-gain stable configurations?
Yes, the TLE2024CDWR is unity-gain stable with ≥42° phase margin (±15 V, 25°C). Its Excalibur process and internal compensation ensure stable operation in voltage-follower, inverting, and non-inverting configurations down to gain = 1, provided layout follows standard high-frequency op-amp practices (e.g., short traces, proper decoupling).
What is the thermal dissipation capability of the TLE2024CDWR in its CDIP package?
The TLE2024CDWR in the 14-pin CDIP (J) package has a maximum continuous power dissipation of 1375 mW at TA ≤ 25°C, derating linearly at 11.0 mW/°C above 25°C. At 70°C ambient, usable power drops to 880 mW-sufficient for typical operation at 1.4 mA total supply current and moderate output loading.
