Product details
Overview
TLE2024BMDWR from Texas Instruments is a quad-channel, precision bipolar operational amplifier optimized for low-power, high-speed signal conditioning in single-supply (5V) and split-supply (±15V) configurations. It delivers 2 MHz unity-gain bandwidth, 0.65 V/µs slew rate, 100 µV max input offset voltage, 300 µA max supply current, and rail-to-rail common-mode input range extending to the negative rail - enabling accurate amplification of low-level sensor signals in industrial transmitters and analog input modules.
For engineers reviewing the TLE2024BMDWR datasheet, TLE2024BMDWR pinout, TLE2024BMDWR application, or TLE2024BMDWR equivalent, this device is selected for precision DC-coupled amplification where phase-reversal protection, stable dc performance over temperature (–55°C to +125°C), and low noise (19 nV/√Hz) are critical in flow/pressure transmitter front-ends and lab instrumentation signal chains.
Technical Context
The TLE2024BMDWR 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, gain, and CMRR across the full military temperature range.
It integrates phase-reversal protection to prevent output polarity inversion when either input falls below the negative supply rail - a key reliability feature in single-supply systems with transient input excursions. The device supports both 5V single-supply operation (VICR down to 0 V) and ±15V dual-supply operation (VICR from –15 V to +13.2 V at TA = –55°C to +125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-channel signal conditioning without discrete op-amp duplication. |
| Supply Current | 300 µA max - allows battery-powered or energy-constrained systems to integrate precision amplification with minimal quiescent load. |
| Unity-Gain Bandwidth | 2 MHz - supports stable closed-loop gain ≥1 up to audio-frequency and low-speed data acquisition bandwidths. |
| Slew Rate | 0.65 V/µs - ensures faithful reproduction of fast step inputs (e.g., pulse conditioning) without distortion in sensor interfaces. |
| Input Offset Voltage | 100 µV max - guarantees ≤0.002% gain error in 5V full-scale systems, critical for 16-bit+ ADC front-ends. |
| Input Voltage Noise | 19 nV/√Hz @ 10 Hz - minimizes added noise in low-frequency sensor amplification (e.g., strain gauge, thermopile). |
| Common-Mode Range | Includes negative rail (0 V in 5V mode) - enables direct interfacing to ground-referenced sensors without level-shifting circuitry. |

Pinout & Package
Package: DW (SOIC-16), 16-pin small-outline integrated circuit with standard 0.050″ lead pitch and gull-wing leads. Thermal resistance RθJA = 62.7°C/W enables reliable operation at full military temperature range with moderate PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A, OUT B, OUT C, OUT D | Amplified outputs for each of four independent op-amp channels. |
| 2, 6, 9, 13 | –IN A, –IN B, –IN C, –IN D | Inverting inputs - accept feedback networks and differential signal paths. |
| 3, 5, 10, 12 | +IN A, +IN B, +IN C, +IN D | Noninverting inputs - connect to sensors, references, or signal sources requiring high-Z interface. |
| 4 | VCC+ | Positive supply terminal - accepts +5V (single) or +15V (dual) rail. |
| 11, 13 | VCC– | Negative supply terminal - tied to 0V (single) or –15V (dual); pin 13 is shared with VCC– in DW package per TI datasheet Figure 5-4. |
| 8, 9 | NC | No-connect pins - must remain unconnected; no internal function or test access. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | FET-input (not bipolar), 1.1 nV/√Hz noise, 80 mA ICC, 45 MHz GBW - higher speed, lower noise, but 10× higher supply current and no phase-reversal protection. | Best for low-noise, high-bandwidth applications where power is not constrained and input overdrive is controlled. | Select OPA211IDR only if 45 MHz bandwidth and sub-2 nV/√Hz noise are required; avoid where phase-reversal immunity or <300 µA ICC is mandatory. |
| LMC6084IMX/NOPB | CMOS-input, rail-to-rail I/O, 2.5 µV max VIO, 1.1 mA ICC, 1.4 MHz GBW - lower offset, but higher current, lower slew rate (0.35 V/µs), and no phase-reversal protection. | Suitable for ultra-low-offset, low-voltage (2.7V) applications where bipolar speed and robustness are secondary. | Choose LMC6084IMX/NOPB for sub-µV offset needs in battery-powered portable instruments; reject for industrial transmitters requiring military temp range and phase-reversal safety. |
Compared with OPA211IDR and LMC6084IMX/NOPB, the TLE2024BMDWR uniquely balances military-temperature operation, phase-reversal immunity, 2 MHz bandwidth, and microamp quiescent current - making it irreplaceable in ruggedized, low-power, precision analog front-ends where input fault tolerance is non-negotiable.

FAQ
What is the maximum supply voltage rating for TLE2024BMDWR?
The TLE2024BMDWR has an absolute maximum supply voltage of ±20 V (VCC+ to VCC–), with recommended operating range of ±2 V to ±20 V for dual supply or 4 V to 40 V for single supply. Operation beyond ±20 V risks permanent damage; for 5V single-supply use, VCC+ = 5V and VCC– = 0V is standard and fully supported per datasheet Section 6.2.
Does TLE2024BMDWR support true rail-to-rail output swing?
No, the TLE2024BMDWR does not provide rail-to-rail output swing. In ±15V operation, output swing is typically ±14.3 V (min ±13.6 V at TA = –55°C to +125°C); in 5V operation, it swings from ~0.7 V to ~4.3 V. However, its input common-mode range *does* include the negative rail - a key distinction confirmed in Table 6.2 and Section 6.6 VICR specs for TLE2024BMDWR.
What is the meaning of the 'B' suffix in TLE2024BMDWR?
The 'B' suffix in TLE2024BMDWR denotes the improved input offset voltage grade: 100 µV max (vs. 500 µV max for standard 'C' grade), achieved through enhanced trimming and process control. This grade is specified across the full –55°C to +125°C temperature range and applies exclusively to the M-suffix military-qualified variants like TLE2024BMDWR and TLE2024BM.
How does phase-reversal protection work in TLE2024BMDWR?
TLE2024BMDWR incorporates internal circuitry that actively clamps the differential input voltage during overdrive conditions where one input falls below VCC–. This prevents the output from reversing polarity - a failure mode common in standard bipolar op-amps. The protection operates continuously across the full –55°C to +125°C range and is verified in TI's characterization testing per datasheet Section 3.
Is TLE2024BMDWR pin-compatible with other TLE2024 variants in SOIC-16?
Yes, TLE2024BMDWR is pin-compatible with all TLE2024x variants in the DW (SOIC-16) package, including TLE2024ACDW, TLE2024CDW, TLE2024IDW, and TLE2024AMDWR. Pin functions, spacing, and thermal pad layout match exactly per TI's mechanical drawing SLAS122 - enabling drop-in replacement for offset, temperature, or grade upgrades without PCB modification.
