Product details
Overview
TLE2024MFKB from Texas Instruments is a quad-channel, military-grade precision operational amplifier optimized for low-power, high-speed signal conditioning in harsh environments. It delivers 2 MHz unity-gain bandwidth, 0.65 V/µs slew rate, and ≤100 µV max input offset voltage across –55°C to +125°C, enabling accurate amplification of low-level sensor outputs in flow and pressure transmitters.
For engineers reviewing the TLE2024MFKB datasheet, TLE2024MFKB pinout, TLE2024MFKB application, or TLE2024MFKB equivalent, this page provides verified electrical specs, military-temperature SOIC-16 pin mapping, phase-reversal protection details, and validated alternatives for analog input modules requiring rail-to-rail common-mode input range and single- or dual-supply operation.
Technical Context
The TLE2024MFKB uses Texas Instruments' proprietary complementary bipolar process with isolated vertical PNP transistors, enabling higher unity-gain bandwidth and slew rate than legacy OP21-based designs while maintaining precision DC performance. Its bias circuit ensures stable parameters over temperature and time.
It features phase-reversal protection that prevents output inversion when inputs fall below the negative supply rail - critical for industrial sensors operating near ground in single-supply configurations. The device supports both ±15 V and 5 V single-supply operation with a common-mode input range extending to the negative rail.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-channel signal conditioning without board space penalty. |
| Supply Current | ≤300 µA max at –55°C to +125°C - supports battery-powered or thermally constrained systems. |
| Unity-Gain Bandwidth | 2 MHz - sufficient for anti-aliasing, sensor interface, and moderate-speed control loops. |
| Slew Rate | 0.65 V/µs - handles fast transient signals (e.g., pressure spikes) without distortion. |
| Input Offset Voltage | ≤100 µV max (TLE2024BM variant per Table 4-3) - ensures <1 LSB error in 16-bit ADC front-ends. |
| Common-Mode Input Range | Includes negative rail (to –15 V or 0 V) - allows direct interfacing with grounded sensors in single-supply systems. |
| Phase-Reversal Protection | Integrated - eliminates risk of output latch-up or system fault during input overdrive. |
Pinout & Package
Package: DW (SOIC-16), 16-pin small-outline integrated circuit, surface-mount, 7.5 mm × 10.3 mm body, 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A–D | Amplified output channels A through D - each independently buffered and rail-swing capable. |
| 2, 6, 9, 13 | –IN A–D | Inverting inputs - accept differential or single-ended signals with matched layout sensitivity. |
| 3, 5, 10, 12 | +IN A–D | Noninverting inputs - support high-impedance sensor connections with minimal loading. |
| 4 | VCC+ | Positive supply terminal - accepts up to +20 V; must be decoupled locally for stability. |
| 11 | VCC– | Negative supply terminal - accepts down to –20 V; referenced for all input/output swing. |
| 8, 9 | NC | No-connect pins - left unconnected per TI design; no internal function or thermal role. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail common-mode input | Operates with inputs at VCC– (0 V or –15 V), eliminating level-shifting for grounded sensors. |
| Phase-reversal protection | Prevents output inversion during input overdrive - avoids false triggering in safety-critical monitoring. |
| Military temperature rating | Qualified from –55°C to +125°C - suitable for avionics, downhole tools, and engine control units. |
| Low 1/f noise | 0.16 µVPP (0.1–1 Hz) - preserves signal integrity in precision DC-coupled measurement paths. |
| High open-loop gain | 6.5 V/µV (136 dB) - ensures <0.001% gain error in closed-loop configurations with modest feedback ratios. |
Applications
| Flow Transmitter Signal Conditioning | Pressure Transmitter Front-End |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2188AIDR | Single-supply only (4.5–36 V); lower noise (8.8 nV/√Hz); no phase-reversal protection. | Optimized for battery-powered portable instruments; not rated for military temperature range. | Choose for ultra-low-noise, single-supply systems where phase reversal is mitigated externally. |
| AD8629ARZ | Zero-drift architecture; 1 µV max offset; 0.01 µV/°C drift; 2.5 MHz GBW; SOIC-8 package. | Superior DC accuracy but dual-channel only; requires two ICs for quad functionality. | Choose when long-term offset stability dominates over channel count and military temp qualification. |
Compared with OPA2188AIDR and AD8629ARZ, the TLE2024MFKB uniquely combines quad-channel integration, phase-reversal protection, and full military temperature qualification - making it irreplaceable in ruggedized multi-sensor analog input systems where reliability under extreme conditions is non-negotiable.

FAQ
What is the maximum operating temperature range for the TLE2024MFKB?
The TLE2024MFKB is qualified for continuous operation from –55°C to +125°C, meeting MIL-PRF-38535 requirements for military-grade devices. This range is explicitly confirmed in Table 4-3 of the datasheet for the TLE2024BM variant, which corresponds to the TLE2024MFKB's DW package and M-suffix temperature grade.
Does the TLE2024MFKB support single-supply operation?
Yes, the TLE2024MFKB is fully specified for 5 V single-supply operation, with guaranteed performance including common-mode input range to the negative rail (0 V), output swing within 0.7 V of rails, and 0.5 V/µs slew rate. These parameters are documented in Section 6.7 of the datasheet under VCC = 5 V conditions.
What does "phase-reversal protection" mean for the TLE2024MFKB?
Phase-reversal protection in the TLE2024MFKB prevents the output from inverting polarity when either input falls below the negative supply rail - a failure mode common in standard op-amps. This feature eliminates unexpected system behavior during power-up, sensor disconnect, or overvoltage events in grounded-input applications.
Is the TLE2024MFKB pin-compatible with other TLE202x variants?
No - the TLE2024MFKB uses the DW (SOIC-16) package, while TLE2021 and TLE2022 use 8-pin packages (SOIC-8/PDIP-8). The TLE2024 itself is only offered in DW (16-pin) and N (PDIP-14) packages; no 8-pin quad variant exists. Pin compatibility applies only within the same package type and channel count.
What is the typical input bias current for the TLE2024MFKB?
The typical input bias current for the TLE2024MFKB is 25 nA, with a maximum of 70 nA across the full –55°C to +125°C temperature range (per Section 6.6, Table 6-1, IIB parameter). This low bias current minimizes voltage errors when driving high-impedance sources like thermocouples or pH electrodes.
