Product details
Overview
LM2904VQPWR from Texas Instruments is a dual general-purpose operational amplifier optimized for industrial and automotive applications, featuring rail-to-rail input (including ground), 36V max supply voltage, 1.2MHz unity-gain bandwidth, 300µA/ch quiescent current, and ±2mV max input offset voltage at 25°C (BA-grade). It serves as a precision signal conditioning and feedback amplifier in motor control, power supply monitoring, and sensor interface circuits.
For engineers reviewing the LM2904VQPWR datasheet, LM2904VQPWR pinout, LM2904VQPWR application, or LM2904VQPWR equivalent, key selection criteria include its extended temperature range (–40°C to +125°C), integrated EMI/RF filtering, SOIC-8 package compatibility, and verified performance under single-supply operation with VCM extending to ground.
Technical Context
The LM2904VQPWR belongs to the enhanced LM2904B/BA family, sharing identical internal architecture with the LM2904BA - including complementary NPN/PNP input stage enabling true ground-sensing capability, unity-gain stable compensation, and high common-mode rejection (>100 dB) over full operating temperature. Its differential input voltage rating of ±32V supports robust interfacing with noisy industrial signals.
Unlike legacy LM2904 variants, the LM2904VQPWR implements improved ESD protection (2kV HBM), lower input bias current (≤35 nA max), and tighter offset drift (±3.5 µV/°C) across –40°C to +125°C, making it suitable for closed-loop analog sensing where thermal stability and long-term DC accuracy are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 36V - supports wide-input industrial power rails and battery-backed systems without external regulation. |
| Input Offset Voltage (max) | ±2 mV at 25°C - enables accurate low-level signal amplification (e.g., shunt-based current sensing) without trimming. |
| Unity-Gain Bandwidth | 1.2 MHz - sufficient for motor control loop compensation, active filters up to ~100 kHz, and fast-settling ADC drivers. |
| Quiescent Current / ch | 300 µA typical - allows dual op-amp integration in power-constrained embedded nodes without compromising battery life. |
| Common-Mode Input Range | Includes ground (V–) - permits direct interface with 0V-referenced sensors (e.g., thermocouples, bridge outputs) in single-supply configurations. |
| ESD Rating (HBM) | 2000 V - meets IEC 61000-4-2 Level 3 immunity requirements for industrial control panel interfaces. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, HVAC, and industrial motor drive environments. |
Pinout & Package
TSSOP-8 (PW) package: 3mm × 6.4mm body, 0.65mm pitch, surface-mount, moisture-sensitive level 1 (MSL-1), RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Drives feedback networks or downstream stages; capable of sourcing/sinking ±20 mA at 25°C. |
| 2 (IN1–) | Amplifier 1 inverting input | Accepts feedback signal or inverted input; high-impedance node (ZIC = 4 GΩ||1.5 pF). |
| 3 (IN1+) | Amplifier 1 non-inverting input | Receives reference or sensor signal; common-mode range extends to V–, enabling ground-referenced inputs. |
| 4 (V–) | Negative supply / ground | Reference for both amplifiers; must be connected even in single-supply use (e.g., 0V when V+ = 12V). |
| 5 (IN2+) | Amplifier 2 non-inverting input | Independent input path; identical electrical specs to Pin 3 - supports dual-channel signal conditioning. |
| 6 (IN2–) | Amplifier 2 inverting input | Matches Pin 2 functionality; enables independent gain-setting resistors per channel. |
| 7 (OUT2) | Amplifier 2 output | Electrically isolated from OUT1; drives separate load or cascaded stage without crosstalk. |
| 8 (V+) | Positive supply | Accepts up to 36V; internal regulation ensures stable biasing across full supply range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (VCM = V–) | Enables direct connection to 0V-referenced transducers (e.g., strain gauges, RTDs) without level-shifting circuitry. |
| Integrated RF/EMI filter | Reduces susceptibility to conducted noise in motor drive and switching power supply environments (e.g., PWM edge coupling). |
| Low input offset drift | ±3.5 µV/°C max ensures <±0.5 mV total offset shift over –40°C to +125°C - critical for unattended industrial instrumentation. |
| High open-loop gain (70 V/mV) | Supports precise closed-loop gain accuracy (e.g., 0.1% error at G = 100) with minimal dependence on resistor tolerance. |
| Capacitive load drive (100 pF) | Stable operation into typical PCB trace capacitance and ADC input filters without external isolation resistors. |

FAQ
What is the maximum supply voltage rating for LM2904VQPWR?
The LM2904VQPWR supports a maximum supply voltage of 36V across its V+ and V– pins. This rating is absolute and applies across the full operating temperature range (–40°C to +125°C). Exceeding this voltage risks permanent damage, and operation above 36V violates the device's Absolute Maximum Ratings specification per TI's SLOS068AB datasheet.
Does LM2904VQPWR support true single-supply operation with input referenced to ground?
Yes, the LM2904VQPWR supports true single-supply operation with its common-mode input voltage range extending to V– (ground). This allows direct connection of sensors or signal sources referenced to 0V - such as shunt resistors, thermistors, or bridge outputs - without external level-shifting circuitry, simplifying design and reducing component count.
What is the input offset voltage specification for LM2904VQPWR at 25°C and over temperature?
The LM2904VQPWR has a maximum input offset voltage of ±2 mV at 25°C and ±3 mV over its full operating temperature range of –40°C to +125°C. This BA-grade precision is confirmed in Section 5.6 of the TI SLOS068AB datasheet and distinguishes it from standard LM2904 (±3 mV at 25°C) and LM2904V (±7 mV at 25°C) variants.
Is LM2904VQPWR pin-compatible with standard LM2904 devices in TSSOP-8 package?
Yes, the LM2904VQPWR uses the industry-standard TSSOP-8 (PW) footprint and shares identical pin configuration and function with LM2904QPWR, LM2904BQPWR, and LM358BQPWR. No PCB layout changes are required for drop-in replacement, provided the system design accommodates its tighter offset and extended temperature performance.
What packaging and environmental compliance does LM2904VQPWR meet?
The LM2904VQPWR is supplied in a RoHS-compliant, lead-free TSSOP-8 (PW) package rated MSL-1 (moisture sensitivity level 1), meaning it may be stored indefinitely at ≤30°C/85% RH without baking prior to reflow. It is qualified to AEC-Q100 Grade 1 for automotive applications and meets JEDEC J-STD-020 moisture sensitivity standards.
