Product details
Overview
LM7332MME/NOPB from Texas Instruments is a dual rail-to-rail input/output operational amplifier designed for high-current, wide-supply-voltage applications including MOSFET drivers, current sensing, and precision analog signal conditioning. It delivers ±125mA output current, operates from 2.7V to 32V, features 24MHz gain-bandwidth product and 35V/µs slew rate, and supports −40°C to +125°C industrial temperature range.
For engineers reviewing the LM7332MME/NOPB datasheet, LM7332MME/NOPB pinout, LM7332MME/NOPB application, or LM7332MME/NOPB equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The LM7332MME/NOPB integrates two independent amplifiers sharing a common supply domain, each capable of sourcing and sinking ≥125mA while maintaining rail-to-rail input common-mode range (−0.1V to VS + 0.1V) and rail-to-rail output swing (within 250mV of either rail at 10kΩ load). Its internal architecture enables stable operation with unlimited capacitive loads without external compensation.
Key design-enabling traits include supply-insensitive parameters (e.g., CMRR >109dB across 2.7–32V), low total supply current (2.7mA typical), and robust ESD protection (±2000V HBM). The device uses dual complementary input stages to achieve extended common-mode range beyond rails and maintains specified performance over full −40°C to +125°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 32V - supports single-supply battery systems (e.g., 12V/24V automotive) and split-rail industrial supplies (±15V) without redesign. |
| Output Current | ±125mA - drives power transistors, bridge sensors, or DAC outputs directly, eliminating discrete buffer stages. |
| Gain-Bandwidth Product | 24MHz - enables stable closed-loop operation up to ~1MHz at G = 24, suitable for fast-settling SAR ADC drivers. |
| Slew Rate | 35V/µs - ensures <1µs settling for 10V step with minimal overshoot, critical in data acquisition and PWM control loops. |
| Input Common-Mode Range | −0.1V to VS + 0.1V - allows high-side and low-side current sensing without level-shifting circuitry. |
| Capacitive Load Drive | Unlimited - eliminates need for isolation resistors when driving ADC inputs, LCD bias networks, or long cables. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial motor control, and outdoor power electronics. |
Pinout & Package
LM7332MME/NOPB is packaged in an 8-pin VSSOP (DGK) measuring 3.00mm × 3.00mm, optimized for space-constrained PCB layouts while maintaining thermal performance (RθJA = 169.6°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+ A (Pin 3) | Non-inverting input, Amplifier A | Accepts signals up to 0.1V beyond V− or V+, enabling direct connection to shunt resistors or sensor bridges. |
| IN− A (Pin 2) | Inverting input, Amplifier A | Supports unity-gain inverting configurations and precision current-sense feedback paths. |
| OUT A (Pin 1) | Output, Amplifier A | Delivers ±125mA into loads; rail-to-rail swing allows full utilization of 0–5V or 0–3.3V ADC reference ranges. |
| V− (Pin 4) | Negative supply | Reference for dual-supply operation; accepts ground in single-supply mode (e.g., 0V/24V). |
| V+ (Pin 8) | Positive supply | Accepts up to 32V; internal regulation ensures stable biasing across full voltage range. |
| IN+ B (Pin 5) | Non-inverting input, Amplifier B | Independent channel for dual-loop control (e.g., voltage + current regulation in battery chargers). |
| IN− B (Pin 6) | Inverting input, Amplifier B | Enables differential sensing or active filtering without cross-talk between channels. |
| OUT B (Pin 7) | Output, Amplifier B | Electrically isolated output stage; supports simultaneous high-current drive for dual-path systems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O with extended common-mode range | Operates with inputs 0.3V beyond supply rails and outputs within 250mV of rails - eliminates level shifters in 4–20mA loop transmitters. |
| High-output current (±125mA) | Drives MOSFET gates, solenoid coils, or LED strings directly - reduces bill-of-materials count and board area vs. op-amp + discrete transistor solutions. |
| Unlimited capacitive load drive | Stable with any CL value (including 10µF ceramic or 100nF film) - simplifies layout for SAR ADC front-ends and sensor signal chains. |
| Wide supply range (2.7V–32V) | Single design supports 3.3V microcontrollers, 12V automotive, and 24V industrial buses - improves design reuse across platforms. |
| Low supply current (2.7mA typ.) | Enables always-on monitoring circuits in battery-powered equipment without compromising runtime. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-output-current operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC072CDR | Lower output current (±40mA), narrower supply range (4.5V–16V), no guaranteed rail-to-rail input. | Not suitable for direct MOSFET driving or high-side sensing above 16V; requires level-shifting for 4–20mA loops. | Select TLC072CDR only for low-power, low-voltage (<16V) signal conditioning where output current ≤40mA suffices. |
| OPA2991IDGKR | Higher precision (VOS = ±12µV), lower noise (10.2nV/√Hz), but limited output current (±70mA) and narrower supply (2.7V–30V). | Better for precision instrumentation amplifiers; insufficient for direct power transistor driving or high-current sensor excitation. | Choose OPA2991IDGKR when offset voltage and noise dominate requirements, not output drive capability. |
Compared with TLC072CDR and OPA2991IDGKR, LM7332MME/NOPB uniquely balances wide supply range (2.7V–32V), rail-to-rail I/O, and ±125mA output in a single 8-pin VSSOP package - making it the only option among the three qualified for direct high-side current sensing and 24V MOSFET gate driving without external components.

FAQ
What is the maximum capacitive load the LM7332MME/NOPB can drive without instability?
The LM7332MME/NOPB is explicitly characterized for unlimited capacitive load drive - meaning it remains stable with any value of capacitive load (including 10µF ceramic or 100nF film) without requiring external isolation resistors. This capability is validated across its full operating temperature range (−40°C to +125°C) and supply voltage range (2.7V to 32V), making LM7332MME/NOPB ideal for driving SAR ADC inputs, LCD bias networks, and long cable runs.
Does the LM7332MME/NOPB support true rail-to-rail input operation?
Yes, the LM7332MME/NOPB supports true rail-to-rail input operation with a common-mode voltage range extending from (V−) − 0.1V to (V+) + 0.1V. This allows direct interface with shunt resistors placed on high-side or low-side power paths, sensor bridges biased at supply rails, and 4–20mA loop references - all without external level-shifting circuitry. Verified performance is maintained across −40°C to +125°C.
What is the output current capability of the LM7332MME/NOPB at 32V supply?
At VS = 32V, the LM7332MME/NOPB delivers ±125mA short-circuit output current per amplifier, as specified in the Electrical Characteristics table. This current is sustained under continuous short-circuit conditions at room temperature and remains functional (though thermally limited) at elevated ambient temperatures - enabling direct driving of power transistors, solenoids, and LED arrays without external buffers.
Can the LM7332MME/NOPB operate from a single 3.3V supply?
Yes, the LM7332MME/NOPB is fully specified down to 2.7V supply voltage, making it compatible with 3.3V single-supply systems. At 3.3V, it maintains rail-to-rail input common-mode range (−0.1V to 3.4V), output swing within 300mV of rails (at 2kΩ load), 24MHz GBWP, and 35V/µs slew rate - supporting precision signal conditioning in low-voltage IoT sensors and portable medical devices.
What package options are available for the LM7332MME/NOPB?
The LM7332MME/NOPB is offered exclusively in the 8-pin VSSOP (DGK) package measuring 3.00mm × 3.00mm. This compact, surface-mount package provides excellent thermal performance (RθJA = 169.6°C/W) and is RoHS-compliant and lead-free. While the base LM7332 part number also appears in SOIC-8 (D package), the MME/NOPB suffix specifically denotes the VSSOP variant.
