Product details
Overview
LM2904 MWC from Texas Instruments is a dual, low-power operational amplifier designed for single-supply operation from 3 V to 26 V, featuring rail-to-rail input (including ground), 0.7 mA typical supply current per amplifier, 3 mV typical input offset voltage, and 100 V/mV typical open-loop gain - widely used in industrial sensor signal conditioning and 5-V digital system interface circuits.
For engineers reviewing the LM2904 MWC datasheet, LM2904 MWC pinout, LM2904 MWC application, or LM2904 MWC equivalent, key selection considerations include guaranteed operation from −40°C to 85°C, SOIC-8 package compatibility, input common-mode range extending to ground, and output drive capability into 2-kΩ loads without saturation.
Technical Context
The LM2904 MWC implements two independent, internally frequency-compensated op-amps with bipolar input stages, enabling stable unity-gain operation without external compensation. Its input stage supports common-mode voltages down to ground, and its output stage delivers ±20 mA short-circuit current with rail-swing capability limited by load.
It operates across a 3 V to 26 V single supply (or ±1.5 V to ±13 V split supply), with differential input voltage tolerance of ±26 V and guaranteed performance over −40°C to 85°C ambient - matching TI's standard catalog LM2904 specifications but supplied as wafer sale (YS) with no final packaging or marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 26 V single supply - enables direct use with 5-V or 12-V industrial rails without level-shifting. |
| Input Offset Voltage (Typ) | 3 mV at 25°C - supports accurate DC amplification in transducer interfaces with ≤0.3% initial error. |
| Supply Current (Typ) | 0.7 mA per amplifier - allows battery-powered or low-power systems to integrate dual-channel amplification with minimal quiescent draw. |
| Common-Mode Input Range | 0 V to VCC − 1.5 V - permits direct sensing of signals referenced to ground, e.g., thermistor or bridge outputs. |
| Open-Loop Gain (Typ) | 100 V/mV (140 dB) - ensures high closed-loop accuracy and stability in precision gain configurations. |
| Output Short-Circuit Current | ±40 mA (min) - sustains robust drive into heavy loads or fault conditions without latch-up. |
| Operating Temperature | −40°C to +85°C - meets commercial/industrial ambient requirements without derating. |
Pinout & Package
LM2904 MWC is supplied as a wafer sale (YS) product with no final packaging; however, it maps directly to the industry-standard SOIC-8 (D) package footprint and pinout used by all catalog LM2904 variants. Pin functions are identical across the family and validated per TI SLOS448.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input of amplifier A | Accepts feedback network connection; referenced to ground or virtual ground in standard configurations. |
| 2 | Non-inverting input of amplifier A | Receives sensor or signal source; supports DC-coupled inputs down to 0 V. |
| 3 | Output of amplifier A | Drives loads up to 2 kΩ while maintaining linearity; sinks or sources up to ±40 mA. |
| 4 | Ground (GND) | Reference node for single-supply operation; must be low-impedance to minimize noise coupling. |
| 5 | Non-inverting input of amplifier B | Independent channel input; electrically isolated from amplifier A except via shared supply and substrate. |
| 6 | Inverting input of amplifier B | Supports standard inverting gain configuration; compatible with resistor-based feedback networks. |
| 7 | Output of amplifier B | Dual-channel output enables simultaneous signal processing (e.g., differential pair or dual-stage filtering). |
| 8 | Positive supply (VCC) | Single positive rail input; no negative supply required - simplifies power architecture in embedded systems. |
Key Features

FAQ
What is the operating temperature range for LM2904 MWC?
The LM2904 MWC is specified for operation from −40°C to +85°C ambient temperature, consistent with TI's standard catalog LM2904 qualification. This range is confirmed in the Package Option Addendum and aligns with the device's controlled baseline manufacturing and JEDEC-compliant reliability testing.
Is LM2904 MWC pin-compatible with standard LM2904 SOIC-8 packages?
Yes, LM2904 MWC maps directly to the SOIC-8 (D) package pinout shown in TI SLOS448 - pins 1–8 correspond identically to 1IN−, 1IN+, 1OUT, GND, 2IN+, 2IN−, 2OUT, and VCC. Though supplied as wafer sale (YS), its die design and terminal assignment match the packaged LM2904DR and LM2904P variants.
Does LM2904 MWC support rail-to-rail output swing?
No, LM2904 MWC does not provide rail-to-rail output. Its output voltage swing is typically VCC − 1.5 V (high) and 20 mV above ground (low) under 10-kΩ load, as specified in the electrical characteristics table. It supports rail-to-rail *input*, but output headroom is limited by internal transistor saturation.
What is the maximum supply voltage for LM2904 MWC?
The absolute maximum supply voltage for LM2904 MWC is 26 V, consistent with non-V-suffix LM2904 devices. This is explicitly stated in the Absolute Maximum Ratings table of SLOS448 and applies across the full −40°C to 85°C operating range.
Can LM2904 MWC be used in split-supply configurations?
Yes, LM2904 MWC supports split-supply operation as long as the total supply difference is between 3 V and 26 V, and the positive rail (VCC) remains at least 1.5 V more positive than the input common-mode voltage. For example, ±12 V supplies (24 V total) are valid, provided inputs stay within −10.5 V to +10.5 V.
