Product details
Overview
LM2904PWRG4-JF from Texas Instruments is a dual operational amplifier optimized for industrial and automotive applications, featuring rail-to-rail input (including ground), 3V–36V wide supply range, 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 LM2904PWRG4-JF datasheet, LM2904PWRG4-JF pinout, LM2904PWRG4-JF application, or LM2904PWRG4-JF equivalent, this page delivers verified electrical specs, TSSOP-8 package details, real-world use cases, and validated alternative options - all aligned with TI's SLOS068AB revision October 2024 production data.
Technical Context
The LM2904PWRG4-JF belongs to the LM2904BA variant family, confirmed by its "-JF" suffix (TI internal marking for BA-grade) and TSSOP-8 packaging. It implements a bipolar input stage with common-mode input range extending to V−, enabling single-supply operation down to ground-referenced sensing - critical for current-sense amplifiers and battery-monitoring circuits.
Its 1.2MHz gain-bandwidth product and 0.5V/µs slew rate support stable closed-loop operation at unity gain, while integrated RF/EMI filtering and 2kV HBM ESD rating ensure robustness in electrically noisy environments such as motor drives and industrial inverters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3V to 36V - supports direct integration into 12V/24V industrial rails and wide-input power supplies without regulation. |
| Input Offset Voltage (max, 25°C) | ±2 mV - enables accurate low-level signal amplification (e.g., shunt-based current sensing with <1% error at 100mV full scale). |
| Quiescent Current per Channel | 300 µA (typ) - allows battery-backed or energy-sensitive designs (e.g., always-on HVAC sensors) to maintain dual-amplifier functionality with minimal standby load. |
| Unity-Gain Bandwidth | 1.2 MHz - sufficient for closed-loop control of switched-mode power supplies up to ~100 kHz switching frequency with phase margin >56°. |
| Common-Mode Input Range | Includes V− (ground) - eliminates need for level-shifting circuitry when interfacing with ground-referenced transducers or resistive dividers. |
| ESD Rating (HBM) | ±2000 V - meets IEC 61000-4-2 Level 2 requirements for system-level ESD immunity in end equipment. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial motor drive environments without derating. |
Pinout & Package
TSSOP-8 (PW) package: 3mm × 6.4mm body, 0.65mm pitch, surface-mount, moisture sensitivity level 1 (MSL-1), RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Drives feedback networks or downstream analog stages; capable of sourcing/sinking ±20mA at 15V supply. |
| 2 (IN1–) | Amplifier 1 inverting input | Accepts differential or single-ended signals; high common-mode rejection (≥100 dB) minimizes noise coupling. |
| 3 (IN1+) | Amplifier 1 non-inverting input | Direct connection to ground-referenced sensors (e.g., thermistor divider) enabled by rail-to-rail input capability. |
| 4 (V–) | Negative supply / ground reference | Serves as return path for both amplifiers; must be low-impedance to avoid PSRR degradation. |
| 5 (IN2+) | Amplifier 2 non-inverting input | Independent channel for auxiliary functions (e.g., overvoltage comparator reference or second sensor path). |
| 6 (IN2–) | Amplifier 2 inverting input | Configurable for transimpedance, difference, or instrumentation topologies without external biasing. |
| 7 (OUT2) | Amplifier 2 output | Electrically isolated from OUT1; supports dual independent loops (e.g., current + voltage regulation in SMPS). |
| 8 (V+) | Positive supply | Accepts up to 36V; internal EMI filtering reduces conducted emissions into shared supply rails. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input including ground | Enables direct interface with 0V-referenced sources (e.g., shunt resistors, RTDs) without external biasing or level shifters. |
| ±2 mV max input offset (25°C, BA grade) | Reduces calibration overhead in precision measurement systems - e.g., <0.2% gain error in 12-bit ADC front-ends. |
| Integrated RF and EMI filter | Suppresses high-frequency interference from PWM motor drivers or switch-mode converters, eliminating need for external ferrite beads. |
| Unity-gain stable | Guarantees stability in buffer, follower, and active filter configurations without external compensation components. |
| 2 kV HBM ESD rating | Supports handling and assembly in standard manufacturing lines without special ESD controls beyond Class 1B requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2904DR | SOIC-8 package; same LM2904BA electrical specs but higher thermal resistance (RθJA = 124.7°C/W vs. 171.7°C/W for TSSOP-8). | Better suited for prototyping or through-hole assembly; less optimal for space-constrained PCBs. | Select LM2904DR only if board layout requires SOIC footprint or manual soldering is preferred. |
| LM358BDR | Same SOIC-8 package; lower temperature grade (–40°C to +85°C), 3mV max offset (vs. 2mV), and no integrated EMI filter. | Acceptable for commercial-grade power supplies or consumer electronics where ESD/EMI robustness is secondary. | Choose LM358BDR only for cost-sensitive, non-automotive applications with relaxed accuracy and noise immunity requirements. |
Compared with LM2904DR and LM358BDR, LM2904PWRG4-JF provides superior thermal performance in dense layouts, tighter offset for precision sensing, and built-in EMI filtering - making it the preferred choice for automotive and industrial motor control where reliability and signal integrity are critical.

FAQ
What is the maximum supply voltage for LM2904PWRG4-JF?
The LM2904PWRG4-JF supports a maximum supply voltage of 36V across V+ and V− terminals, as specified in TI's SLOS068AB datasheet Section 5.1. This allows direct operation from unregulated 24V industrial rails or automotive 12V/24V systems with transient headroom. Exceeding 36V risks permanent damage per absolute maximum ratings.
Is LM2904PWRG4-JF pin-compatible with standard LM2904 variants?
Yes, LM2904PWRG4-JF uses the industry-standard TSSOP-8 (PW) pinout identical to all LM2904x variants in that package, including IN1+, IN1−, OUT1, V−, IN2+, IN2−, OUT2, and V+. Pin functions match Table 4-1 in the datasheet, confirming full electrical and mechanical compatibility with existing LM2904-based PCB layouts using PW packaging.
Does LM2904PWRG4-JF support single-supply operation?
Yes, LM2904PWRG4-JF fully supports single-supply operation due to its rail-to-rail input stage that includes the negative rail (V−, typically ground). The common-mode input range extends from V− to (V+ − 1.5V), enabling direct connection of sensors referenced to ground - a key requirement in battery-powered and industrial sensor interfaces.
What is the operating temperature range of LM2904PWRG4-JF?
The LM2904PWRG4-JF is rated for operation from –40°C to +125°C ambient temperature, consistent with the LM2904BA variant specification in Section 5.3 of the TI datasheet. This qualifies it for under-hood automotive applications, industrial motor drives, and outdoor power electronics where thermal stress exceeds commercial-grade limits.
How does the EMI filtering in LM2904PWRG4-JF improve system design?
The integrated RF and EMI filter in LM2904PWRG4-JF attenuates high-frequency noise (e.g., from PWM gate drivers or switching regulators) before it enters the amplifier input stage. This eliminates the need for external RC filters or ferrite beads in sensitive analog paths - reducing BOM count, PCB area, and potential phase-shift errors in feedback loops.
