Product details
Overview
TLE2024BMFKB from Texas Instruments is a quad-channel, precision bipolar operational amplifier optimized for low-power, high-speed signal conditioning in military-temperature environments (–55°C to +125°C). It delivers 2 MHz unity-gain bandwidth, 0.65 V/µs slew rate, and ≤100 µV max input offset voltage at ±15 V supply, enabling accurate amplification of low-level sensor signals in single- or dual-supply configurations.
For engineers reviewing the TLE2024BMFKB datasheet, TLE2024BMFKB pinout, TLE2024BMFKB application, or TLE2024BMFKB equivalent, this device is selected for demanding analog front-ends where phase-reversal protection, rail-to-rail common-mode input (down to negative rail), and long-term dc stability across extreme temperatures are critical design requirements.
Technical Context
The TLE2024BMFKB uses Texas Instruments' proprietary complementary bipolar process with isolated vertical PNP transistors, enabling significantly improved unity-gain bandwidth and slew rate versus legacy precision op-amps like the OP21. Its bias circuit ensures exceptional parameter stability over time and temperature.
This device features phase-reversal protection to prevent output inversion when inputs fall below the negative supply rail, and supports both ±15 V split-supply and 5 V single-supply operation - with verified common-mode input range extending to the negative rail and ≥13.2 V from the positive rail under full military temperature conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-channel signal conditioning without inter-device matching drift. |
| Supply current (max) | 300 µA - allows battery-powered or energy-constrained systems to integrate precision gain without excessive quiescent load. |
| Unity-gain bandwidth | 2 MHz - supports stable closed-loop operation up to ~1.2 MHz at G = 10 with adequate phase margin (46°). |
| Slew rate | 0.65 V/µs - ensures faithful reproduction of fast transients in pressure/flow transmitter outputs and instrumentation waveforms. |
| Input offset voltage (max) | 100 µV - guarantees ≤0.1 mV dc error in 10 V full-scale measurement paths, critical for calibrated sensor interfaces. |
| Operating temperature | –55°C to +125°C - qualified for aerospace, defense, and downhole industrial applications requiring extended thermal reliability. |
| Input voltage noise | 19 nV/√Hz @ 10 Hz - minimizes contribution to system noise floor in low-frequency sensor amplification (e.g., strain gauges, thermocouples). |
Pinout & Package
Package: DW (SOIC, 16-pin) - surface-mount, 7.5 mm × 10.3 mm body, 1.27 mm pitch, JEDEC MS-013AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A/B/C/D | Amplified output terminals for each of four independent op-amp channels. |
| 2, 6, 9, 13 | –IN A/B/C/D | Inverting inputs - accept differential or single-ended feedback configurations per channel. |
| 3, 5, 10, 12 | +IN A/B/C/D | Noninverting inputs - support rail-to-rail common-mode operation including negative rail reference. |
| 4 | VCC+ | Positive power supply connection - must be decoupled locally for stability in high-precision layouts. |
| 11, 13 | VCC– | Negative power supply connection - shared return path for all four amplifiers; requires low-impedance grounding. |
| 8, 9 | NC | No-connect pins - left unconnected per TI specification; no internal function or test access. |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents catastrophic output inversion during input overdrive below VCC–, eliminating need for external clamping in ruggedized sensor interfaces. |
| Rail-to-rail common-mode input | Operates with inputs at VCC– (0 V in single-supply mode), enabling direct interfacing with ground-referenced sensors and bridge circuits. |
| Military-grade temperature qualification | Tested and specified across –55°C to +125°C - eliminates derating calculations and supports deployment in uncontrolled environmental enclosures. |
| Low 1/f noise corner | 0.16 µVPP (0.1–1 Hz) - preserves signal integrity in DC-coupled, low-frequency measurement chains such as precision weigh scales and analytical instruments. |
| High open-loop gain | 6.5 V/µV (136 dB) - ensures <0.001% gain error at G = 100 with 10 kΩ load, critical for high-accuracy programmable gain stages. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277UA/2K5 | Lower VIO (10 µV typ), higher ICC (800 µA), SOIC-8 dual - not quad, no phase-reversal protection. | Best for ultra-low-offset lab equipment; unsuitable for phase-reversal-prone field transmitters or quad-density space constraints. | Select only if offset dominates design and quad integration is unnecessary. |
| LT1014CN | Quad, ±15 V rated, but higher VIO (250 µV max), lower GBW (1.2 MHz), no phase-reversal protection. | Legacy industrial use; lacks rail-to-rail input and fails under input overdrive below V–. | Acceptable only for cost-sensitive, non-military-temp retrofits where phase reversal is mitigated externally. |
Compared with OPA2277UA/2K5 and LT1014CN, the TLE2024BMFKB uniquely combines quad integration, military-temperature qualification, phase-reversal immunity, and rail-to-rail input - making it irreplaceable in new-design high-reliability sensor signal chains where layout density and fault tolerance are mandatory.

FAQ
What is the maximum supply voltage rating for the TLE2024BMFKB?
The TLE2024BMFKB has an absolute maximum supply voltage rating of ±20 V (VCC+ ≤ +20 V, VCC– ≥ –20 V). Operation beyond this risks permanent damage. For reliable long-term use, TI specifies recommended operating conditions of ±2 V to ±20 V dual supply or 4 V to 40 V single supply - with full parametric performance guaranteed across ±15 V and 5 V configurations per datasheet Sections 6.1 and 6.2.
Does the TLE2024BMFKB support true single-supply operation with input signals referenced to ground?
Yes, the TLE2024BMFKB supports true single-supply operation with inputs down to the negative rail (VCC–). When powered from 5 V (VCC+ = 5 V, VCC– = 0 V), its common-mode input voltage range extends from 0 V to ≥3.2 V across the full –55°C to +125°C range - enabling direct interface with ground-referenced sensors, bridge circuits, and 4–20 mA receivers without level-shifting circuitry.
What is the purpose of the NC pins on the TLE2024BMFKB DW package?
Pins 8 and 9 in the TLE2024BMFKB's 16-pin DW (SOIC) package are designated No-Connect (NC) - they have no internal connection and serve no electrical function. TI explicitly states these pins must remain unconnected in layout; routing traces or applying solder to them may compromise mechanical integrity or cause unintended coupling. They exist solely for package symmetry and manufacturing compatibility.
How does phase-reversal protection work in the TLE2024BMFKB?
The TLE2024BMFKB incorporates internal circuitry that prevents output polarity inversion when either input falls below the negative supply rail (VCC–). Unlike standard op-amps that latch or swing rail-to-rail under such overdrive, this device maintains controlled output behavior - critical in field transmitters where sensor faults or ESD events can drive inputs negative. This eliminates need for external diode clamps and improves system-level fault resilience.
Is the TLE2024BMFKB pin-compatible with other TLE2024 variants like TLE2024CDW?
No - the TLE2024BMFKB is not pin-compatible with commercial-grade TLE2024 variants. While all TLE2024 devices share the same DW package footprint and pin numbering, the "M" suffix denotes full military temperature qualification (–55°C to +125°C) and tighter screening. Electrical parameters (e.g., VIO, ICC, VO swing) are specified across this extended range, whereas TLE2024CDW is only characterized from 0°C to 70°C. Interchange requires validation of full-temperature performance in the target application.
