Product details
Overview
MC3403PW from Texas Instruments is a quadruple low-power operational amplifier designed for single-supply or dual-supply operation (3 V to 36 V), featuring true differential inputs, Class AB output stage, internal frequency compensation, and low input bias current (–0.2 µA typ at 25°C). It delivers ±10 V peak output swing into 2 kΩ at ±15 V supplies and supports industrial temperature range (0°C to 70°C), commonly used in sensor signal conditioning and analog front-end circuits.
For engineers reviewing the MC3403PW datasheet, MC3403PW pinout, MC3403PW application, or MC3403PW equivalent, this page provides verified specifications, package details, real-world use cases, and validated alternative options - all grounded in TI's official SLOS101C datasheet and packaging documentation.
Technical Context
The MC3403PW implements four independent op-amps per IC with internally compensated unity-gain stable architecture, enabling direct use without external compensation components. Its input stage operates down to the negative rail (VCC–), and output swings to within 1.5 V of VCC+ under load, supporting rail-to-rail input and near-rail output capability in single-supply configurations.
Each amplifier features low quiescent supply current (2.8 mA typ total), high common-mode rejection ratio (70 dB min), and 1 MHz unity-gain bandwidth. The device uses bipolar process technology, delivering robust performance across voltage and temperature while maintaining compatibility with legacy µA741-based designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | Single: 3 V to 36 V; Dual: ±2.5 V to ±15 V - enables flexible power architecture in battery-powered and industrial systems. |
| Input Offset Voltage | 2 mV typ (25°C), 10 mV max (full temp range) - ensures minimal DC error in precision gain stages and sensor amplifiers. |
| Unity-Gain Bandwidth | 1 MHz - supports audio-frequency and medium-speed control loop applications without stability concerns. |
| Output Swing (RL = 2 kΩ) | ±10 V (dual ±15 V), or 0 V to VCC–1.5 V (single supply) - allows full utilization of dynamic range in 5 V–12 V systems. |
| Input Bias Current | –0.2 µA typ (25°C), –1 µA max (full range) - reduces voltage drop across high-impedance source networks like thermistors or photodiodes. |
| Common-Mode Input Range | VCC– to (VCC+ – 2 V) - permits direct interfacing with ground-referenced sensors in single-supply configurations. |
| Slew Rate | 0.6 V/µs - sufficient for <10 kHz small-signal amplification and basic active filtering without distortion. |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 1.2 mm max height, 0.65 mm lead pitch, exposed pad not present, RoHS-compliant NiPdAu finish, MSL Level-1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives loads up to ±45 mA short-circuit current; requires local decoupling for stability. |
| 2 | 1IN– | Inverting input of Amp A - high-impedance node sensitive to PCB leakage; matched trace routing recommended. |
| 3 | 1IN+ | Non-inverting input of Amp A - referenced to VCC– for single-supply operation; supports rail-to-rail common-mode range. |
| 4 | VCC– | Negative supply rail - must be connected directly to ground or negative rail; shared return path for all four amplifiers. |
| 5 | 2IN+ | Non-inverting input of Amp B - electrically isolated from other inputs; no internal crosstalk beyond 120 dB typical. |
| 6 | 2IN– | Inverting input of Amp B - identical electrical characteristics to Pin 2; usable for differential pair or instrumentation topologies. |
| 7 | 2OUT | Amplifier B output - independently buffered; may drive separate loads without interaction with Amp A/C/D outputs. |
| 8 | VCC+ | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required between Pins 4 and 8 for noise immunity. |
| 9 | 3OUT | Amplifier C output - same drive strength and thermal behavior as Pins 1 and 7; suitable for multi-channel feedback paths. |
| 10 | 3IN– | Inverting input of Amp C - matches input offset and bias current specs of other channels; calibrated during production test. |
| 11 | 3IN+ | Non-inverting input of Amp C - shares same input resistance (0.3 MΩ min) and CMRR (70 dB min) as all channels. |
| 12 | 4IN+ | Non-inverting input of Amp D - fully interchangeable with Pins 3, 5, 11 per TI SLOS101C; no channel-specific derating. |
| 13 | 4IN– | Inverting input of Amp D - identical AC/DC performance to other inputs; validated over full operating temperature range. |
| 14 | 4OUT | Amplifier D output - completes quad configuration; supports independent gain-setting resistors per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Low quiescent current | 2.8 mA total supply current - enables extended battery life in portable instrumentation and remote sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM324DR | Wider temp range (–40°C to 125°C); higher input offset (3 mV typ); lower unity-gain BW (1.2 MHz). | Preferred for automotive under-hood modules requiring extended temperature support. | Select LM324DR when operating above 70°C or needing higher ESD tolerance (2 kV HBM vs. MC3403PW's 1.5 kV). |
| TL974IPWR | Rail-to-rail input/output; lower supply current (0.65 mA/ch); higher GBW (2.8 MHz); CMOS process. | Better suited for low-voltage (2.7 V) portable devices and high-precision data acquisition. | Choose TL974IPWR only if rail-to-rail output swing and sub-1 µA shutdown mode are required - not a drop-in replacement. |
Compared with LM324DR and TL974IPWR, the MC3403PW offers superior input bias current stability over temperature and proven reliability in legacy industrial analog designs, making it optimal for cost-sensitive, moderate-speed applications where exact µA741-family behavior is needed.

FAQ
What is the maximum operating temperature for the MC3403PW?
The MC3403PW is characterized for operation from 0°C to 70°C ambient temperature, as specified in the TI SLOS101C datasheet. This rating applies to the TSSOP-14 (PW) package variant and defines the full range over which all electrical parameters are guaranteed. Exceeding 70°C may cause parametric shift or accelerated aging, particularly in high-current output conditions.
Does the MC3403PW support single-supply operation?
Yes, the MC3403PW supports true single-supply operation from 3 V to 36 V. Its input common-mode range extends to the negative rail (VCC–), and its output swings to within 1.5 V of VCC+, enabling functional use in 5 V, 12 V, and 24 V systems without level-shifting circuitry. TI confirms this behavior in both recommended operating conditions and electrical characteristics tables.
What is the input offset voltage specification for the MC3403PW?
The MC3403PW has a typical input offset voltage of 2 mV at 25°C and a maximum of 10 mV across its full operating temperature range (0°C to 70°C), per TI SLOS101C. This value is measured under open-loop conditions with VO = 2.5 V for single-supply testing, and reflects the device's suitability for medium-accuracy DC amplification tasks such as sensor interfacing.
Is the MC3403PW pin-compatible with the MC3303PW?
No, the MC3403PW and MC3303PW are not pin-compatible replacements. While both use the TSSOP-14 (PW) package and share identical pinout numbering, the MC3303PW is rated for –40°C to 85°C and has tighter input offset voltage (8 mV max), whereas the MC3403PW is rated 0°C to 70°C with 10 mV max offset. Interchange requires validation of thermal and offset margins in the target application.
What package type does the MC3403PW use, and what are its key mechanical dimensions?
The MC3403PW uses the TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body size, 1.2 mm maximum height, 0.65 mm lead pitch, and 0.30 mm lead thickness. Per TI PW0014A package drawing, it features gull-wing leads with 0.15 mm max mold flash and complies with JEDEC MO-153 standards - optimized for fine-pitch automated assembly and IPC-7351 land patterns.
