Product details
Overview
MC3403PWG4 from Texas Instruments is a quadruple low-power operational amplifier with Class AB output stage, true differential input, and internal frequency compensation. It operates from single supply (3 V to 36 V) or dual supplies (±2.5 V to ±15 V), delivers ±10 V output swing into 2 kΩ at ±15 V, and features 1 MHz unity-gain bandwidth and 0.6 V/µs slew rate - used in precision signal conditioning for industrial sensor interfaces.
For engineers reviewing the MC3403PWG4 datasheet, MC3403PWG4 pinout, MC3403PWG4 application, or MC3403PWG4 equivalent, key selection criteria include input offset voltage (≤10 mV), input bias current (–0.5 µA typ), common-mode input range extending to VCC–, thermal performance in TSSOP-14 (θJA = 113°C/W), and compatibility with legacy µA741-based designs requiring low quiescent current (2.8 mA typ).
Technical Context
The MC3403PWG4 implements four independent op-amps sharing a common bias circuitry and Class AB output stage per amplifier. Each channel features a true differential input stage with input resistance of 0.3 MΩ min and common-mode input range from VCC– to VCC+ – 2 V.
It uses internal frequency compensation for unity-gain stability, supports rail-to-rail input (down to negative rail), and provides short-circuit protection with ±45 mA peak output current. The device is characterized for 0°C to 70°C operation and specified for single-supply (3–36 V) or dual-supply (±2.5 V to ±15 V) configurations.
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 direct interface with 5 V, 12 V, and 24 V industrial systems without level-shifting. |
| Input Offset Voltage | ≤10 mV at 25°C - ensures ≤10 mV DC error in precision DC-coupled amplifiers and active filters. |
| Unity-Gain Bandwidth | 1 MHz - supports stable closed-loop gain ≥1 up to ~1 MHz for audio and sensor signal conditioning. |
| Slew Rate | 0.6 V/µs - limits full-power bandwidth to ~95 kHz at 10 Vpp output, suitable for low-frequency instrumentation. |
| Output Swing | ±10 V into 2 kΩ at ±15 V supplies - delivers usable dynamic range within 1.5 V of positive rail and to negative rail. |
| Quiescent Current | 2.8 mA total (0.7 mA per amplifier) - reduces power budget in battery-powered or thermally constrained multi-channel systems. |
| Common-Mode Input Range | VCC– to VCC+ – 2 V - allows direct sensing of signals referenced to ground in single-supply configurations. |
Pinout & Package
TSSOP-14 package (PW), 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad not electrically connected, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives loads up to ±45 mA; swing limited to VCC– to VCC+ – 1.5 V. |
| 2 | 1IN– | Inverting input of Amp A - high-impedance node (0.3 MΩ); accepts signals down to VCC–. |
| 3 | 1IN+ | Non-inverting input of Amp A - same common-mode range and impedance as 1IN–. |
| 4 | VCC– | Negative supply rail - reference for all four amplifiers; common return for dual-supply operation. |
| 5 | 2IN+ | Non-inverting input of Amp B - electrically isolated from other inputs; shares bias network. |
| 6 | 2IN– | Inverting input of Amp B - matched to 1IN– in offset and bias current specs. |
| 7 | 2OUT | Amplifier B output - identical electrical behavior to 1OUT; no crosstalk beyond 120 dB typical. |
| 8 | VCC+ | Positive supply rail - powers all four amplifiers; must be decoupled locally with 0.1 µF ceramic. |
| 9 | 3OUT | Amplifier C output - fully independent channel; same AC/DC specs as 1OUT. |
| 10 | 3IN– | Inverting input of Amp C - matches input offset voltage drift (10 µV/°C) across temperature. |
| 11 | 3IN+ | Non-inverting input of Amp C - supports rail-to-rail input common-mode range. |
| 12 | 4IN+ | Non-inverting input of Amp D - validated for operation at 0°C to 70°C ambient. |
| 13 | 4IN– | Inverting input of Amp D - exhibits 30 nA max input offset current at 25°C. |
| 14 | 4OUT | Amplifier D output - completes quad configuration; pin-compatible with MC3303PW in same footprint. |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | –0.5 µA typical at 25°C - minimizes voltage error across high-impedance sensor bridges and photodiode feedback networks. |
| Internal frequency compensation | Stable unity-gain operation without external components - eliminates need for compensation capacitors in basic inverting/non-inverting configurations. |
| Class AB output stage | Reduces crossover distortion to 1% at 10 kHz - improves fidelity in audio preamplifier and analog front-end applications. |
| Short-circuit protection | Limits output current to ±45 mA - prevents latch-up and thermal runaway during accidental output shorts. |
| True differential input stage | Enables balanced signal rejection and common-mode noise immunity in instrumentation amplifier configurations. |

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 |
|---|---|---|---|
| MC3303PW | Wider temperature range (–40°C to 85°C); lower input offset voltage (8 mV max vs. 10 mV); same pinout and electrical specs otherwise. | Required for automotive under-hood or industrial outdoor deployments where ambient exceeds 70°C. | Select MC3303PW when extended temperature operation is mandatory; MC3403PWG4 remains optimal for cost-sensitive commercial-grade systems. |
| LM324DR | Higher input offset voltage (7 mV typ, 20 mV max); higher quiescent current (1.4 mA per amp); identical TSSOP-14 package and pinout. | Used in non-critical consumer electronics where tighter DC accuracy is not required. | Choose LM324DR only if legacy LM324 design reuse is prioritized; MC3403PWG4 offers superior VIO and IIB for precision analog front-ends. |
Compared with MC3303PW, MC3403PWG4 trades extended temperature capability for lower cost and qualification scope, while versus LM324DR it delivers tighter input offset and lower bias current - critical for sensor signal chains requiring sub-10 mV DC accuracy and high source impedance compatibility.

FAQ
What is the maximum operating temperature range for the MC3403PWG4?
The MC3403PWG4 is characterized for operation from 0°C to 70°C ambient temperature. This specification is defined in the recommended operating conditions table of the official datasheet (SLOS101C). Operation outside this range may result in parametric degradation or failure. For extended temperature applications, consider the MC3303PW variant rated from –40°C to 85°C. The MC3403PWG4 itself must be used strictly within its 0°C to 70°C envelope to guarantee all published electrical characteristics.
Does the MC3403PWG4 support single-supply operation?
Yes, the MC3403PWG4 supports single-supply operation from 3 V to 36 V. Its common-mode input range extends to the negative supply rail (VCC–), and its output swings from VCC– to VCC+ – 1.5 V - enabling true ground-referenced input and near-rail output in single-supply configurations. This is confirmed in the device description and electrical characteristics sections of the SLOS101C datasheet, where test conditions explicitly include VCC+ = 5 V, VCC– = 0 V.
What is the input offset voltage specification for the MC3403PWG4?
The MC3403PWG4 has a maximum input offset voltage of 10 mV at 25°C and full temperature range (0°C to 70°C), as specified in the "electrical characteristics" table of the SLOS101C datasheet. At 25°C only, the typical value is 2 mV with a maximum of 10 mV. This parameter directly impacts DC accuracy in precision amplification and active filter applications, and is a key differentiator from higher-offset alternatives like the LM324.
Is the MC3403PWG4 pin-compatible with the MC3303PW?
Yes, the MC3403PWG4 is pin-compatible with the MC3303PW. Both devices use the TSSOP-14 (PW) package with identical pinout, footprint, and terminal functions as shown in the "logic diagram" and "top view" diagrams of the SLOS101C datasheet. They differ only in temperature rating (0°C–70°C vs. –40°C–85°C) and input offset voltage (10 mV max vs. 8 mV max), making MC3403PWG4 a direct drop-in replacement in commercial-temperature applications.
What packaging and environmental compliance does the MC3403PWG4 have?
The MC3403PWG4 is supplied in a RoHS-compliant, green (low-halogen) TSSOP-14 (PW) package with NIPDAU lead finish and moisture sensitivity level 1 (MSL-1, 260°C peak reflow). Per TI's Packaging Information Addendum, it meets JEDEC standards for lead-free assembly and carries no bromine or antimony-based flame retardants above 1000 ppm. The "G4" suffix denotes TI's green packaging standard, verified in the official orderable device table on ti.com.
