Product details
Overview
TLE2022BMFKB from Texas Instruments is a dual-channel, military-grade precision operational amplifier optimized for low-power, high-speed signal conditioning in harsh environments. It delivers 2.8 MHz unity-gain bandwidth, 0.65 V/µs slew rate, and ≤500 µV max input offset voltage across –55°C to +125°C, operating on ±15 V or single 5 V supplies. Its rail-to-rail common-mode input range (including negative rail) and phase-reversal protection make it suitable for analog input modules in industrial pressure and flow transmitters.
For engineers reviewing the TLE2022BMFKB datasheet, TLE2022BMFKB pinout, TLE2022BMFKB application, or TLE2022BMFKB equivalent, key selection criteria include guaranteed military-temperature performance, bipolar-input precision with low 19 nV/√Hz noise, stable dc gain (≥0.8 V/µV) at full temperature range, and SOIC-8 packaging compatible with high-density PCB layouts.
Technical Context
The TLE2022BMFKB uses Texas Instruments' complementary bipolar process with isolated vertical PNP transistors, enabling higher unity-gain bandwidth and slew rate than legacy OP21-based designs. Its bias circuit ensures exceptional long-term and thermal stability of offset voltage (±2 µV/°C drift) and gain parameters.
This architecture supports both single-supply (5 V) and split-supply (±15 V) operation while maintaining phase-reversal protection - eliminating output inversion when inputs fall below the negative supply rail. The device's common-mode input range extends to the negative rail, enabling direct interfacing with ground-referenced sensors in low-level signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent op-amps in one SOIC-8 package - reduces board space vs. two single amplifiers. |
| Supply Current | 700 µA max per channel at ±15 V - enables low-power operation in battery-backed or thermally constrained systems. |
| Unity-Gain Bandwidth | 2.8 MHz - supports stable closed-loop gain ≥1 up to ~2.5 MHz without compensation. |
| Slew Rate | 0.65 V/µs - preserves fidelity of fast-rising sensor signals (e.g., piezoelectric pressure pulses). |
| Input Offset Voltage | ≤500 µV over –55°C to +125°C - ensures <1 mV error in 12-bit ADC front-ends without trimming. |
| Input Voltage Noise | 19 nV/√Hz at 10 Hz - critical for low-frequency precision measurement in lab instrumentation. |
| Common-Mode Range | Includes negative rail (to –15 V) - allows direct connection to 0–5 V sensor outputs in single-supply configurations. |
Pinout & Package
Package: SOIC-8 (D package), 3.9 mm × 4.9 mm body, 1.27 mm pitch, surface-mount. RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplified output of Channel A - drives downstream ADC reference buffers or active filters. |
| 2 | –IN A | Inverting input of Channel A - used in transimpedance or inverting gain configurations. |
| 3 | +IN A | Noninverting input of Channel A - accepts high-impedance sensor signals (e.g., RTD bridges). |
| 4 | VCC– | Negative power supply terminal - must be connected to system ground or negative rail; enables rail-to-rail input operation. |
| 5 | +IN B | Noninverting input of Channel B - allows simultaneous dual-sensor conditioning (e.g., differential pressure + temperature). |
| 6 | –IN B | Inverting input of Channel B - supports matched dual-channel instrumentation amplifier topologies. |
| 7 | OUT B | Amplified output of Channel B - provides independent signal path for redundancy or multi-function sensing. |
| 8 | VCC+ | Positive power supply terminal - accepts +5 V (single) or +15 V (dual); decoupling required within 1 cm. |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents catastrophic output inversion when input signals go below VCC– - eliminates need for external clamping diodes in field-deployed transmitters. |
| Military temperature rating | Specified from –55°C to +125°C - qualified for avionics, downhole tools, and engine control units without derating. |
| Bipolar input stage | Low 35–70 nA input bias current - minimizes voltage error across high-value source impedances (>100 kΩ) in bridge sensor interfaces. |
| High PSRR (100 dB min) | Rejects supply ripple and noise - maintains accuracy in electrically noisy industrial cabinets with shared 24 V rails. |
| Rail-to-rail common-mode input | Accepts inputs down to VCC– - enables direct interface with 0–5 V sensors without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277MD | FET-input (not bipolar); lower 0.1 µV/°C drift but higher 65 pA bias current; 1.5 MHz GBW. | Better for ultra-high-impedance sources (>1 MΩ), worse for low-noise <100 kHz applications. | Select OPA2277MD only if input bias current is dominant error source and bandwidth <1.5 MHz suffices. |
| LM158J | Single-supply only; wider offset (±3 mV), slower (0.3 V/µs), no phase-reversal protection; SOIC-8. | Cost-sensitive, non-military applications where 12-bit accuracy and basic functionality suffice. | Choose LM158J only for commercial-temperature, low-performance analog modules with tight BOM cost targets. |
Compared with OPA2277MD and LM158J, the TLE2022BMFKB uniquely combines military-temperature bipolar precision, phase-reversal immunity, and 2.8 MHz bandwidth - making it irreplaceable in high-reliability, wide-temperature industrial sensing where signal integrity and fault tolerance are non-negotiable.

FAQ
What is the maximum operating temperature range for the TLE2022BMFKB?
The TLE2022BMFKB is fully specified from –55°C to +125°C - the full military temperature range. All electrical parameters, including input offset voltage (≤500 µV), supply current (≤700 µA), and open-loop gain (≥0.8 V/µV), are guaranteed across this range per TI's SLVSJD7A datasheet revision.
Does the TLE2022BMFKB support single-supply operation?
Yes, the TLE2022BMFKB operates from a single 5 V supply, with common-mode input range extending to the negative rail (0 V) and output swing from 0.7 V to 4.3 V (RL = 10 kΩ). Its phase-reversal protection remains active, preventing output inversion when inputs go below ground.
What package type is used for the TLE2022BMFKB?
The TLE2022BMFKB uses an SOIC-8 (D package) with 3.9 mm × 4.9 mm body size and 1.27 mm lead pitch. This surface-mount package is compatible with standard reflow profiles and supports high-density PCB layouts typical in industrial I/O modules.
How does the phase-reversal protection in the TLE2022BMFKB work?
The TLE2022BMFKB integrates internal circuitry that prevents output polarity inversion when either input falls below the VCC– rail - a failure mode common in bipolar op-amps. This eliminates the need for external diode clamps in field-wiring scenarios where accidental negative transients may occur.
Is the TLE2022BMFKB pin-compatible with other TLE2022 variants?
Yes, all TLE2022 variants (e.g., TLE2022CDR, TLE2022IDR, TLE2022MFKB) share identical SOIC-8 pinout and footprint. The "M" suffix denotes military temperature qualification, while "F" and "KB" indicate specific TI assembly and test lot coding - no pinout or functional differences exist between variants.
