Product details
Overview
MC3403PWRE4 from Texas Instruments is a quadruple low-power operational amplifier designed for single-supply (3 V to 36 V) or dual-supply (±1.5 V to ±18 V) operation, featuring true differential inputs, Class AB output stage, internal frequency compensation, and 10 mV max input offset voltage at 25°C. It delivers rail-to-rail input common-mode range (to VCC–) and output swing to within 1.5 V of VCC+, supporting precision signal conditioning in industrial sensor interfaces.
For engineers reviewing the MC3403PWRE4 datasheet, MC3403PWRE4 pinout, MC3403PWRE4 application, or MC3403PWRE4 equivalent, this page provides verified electrical parameters, TSSOP-14 package details, thermal resistance (θJA = 113°C/W), supply current (2.8–7 mA), and validated alternatives for legacy analog designs requiring low quiescent power and wide supply flexibility.
Technical Context
The MC3403PWRE4 implements four independent op-amps sharing a common bias circuitry with matched transistor pairs, enabling crosstalk attenuation of 120 dB across 1 kHz–20 kHz. Its Class AB output stage ensures low crossover distortion (1%) and stable unity-gain operation without external compensation.
Designed for interoperability with µA741-level performance but with half the quiescent current, it supports single-supply operation down to 3 V while maintaining 1 MHz unity-gain bandwidth, 0.6 V/µs slew rate, and 70–90 dB common-mode rejection ratio - all specified over 0°C to 70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | Single: 3 V to 36 V; Dual: ±1.5 V to ±18 V - enables direct interface with 3.3 V, 5 V, 12 V, and 24 V industrial rails without level-shifting. |
| Input Offset Voltage | Max 10 mV at 25°C - sets baseline DC error budget for 12-bit ADC front-ends operating near full-scale. |
| Unity-Gain Bandwidth | 1 MHz - supports stable closed-loop gain ≥1 up to audio frequencies with minimal phase lag. |
| Slew Rate | 0.6 V/µs - limits large-signal transient response; sufficient for <10 kHz sine-wave amplification at ±10 VPP. |
| Quiescent Supply Current | 2.8–7 mA total (all four amps) - reduces thermal load in space-constrained PCB layouts and extends battery life in portable instrumentation. |
| Common-Mode Input Range | VCC– to (VCC+ – 2 V) - allows direct sensing of signals referenced to ground in single-supply systems. |
| Output Voltage Swing | VCC– to (VCC+ – 1.5 V) at RL = 2 kΩ - delivers usable dynamic range in 5 V systems (0–3.5 V output). |
Pinout & Package
TSSOP-14 (PW) package: 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm lead pitch, exposed pad not electrically connected, JEDEC MO-153 compliant.
| 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 (0.3–1 MΩ); sensitive to PCB leakage and EMI coupling. |
| 3 | 1IN+ | Non-inverting input of Amp A - matches 1IN– bias current (±0.2–0.5 µA) for minimal offset in differential configurations. |
| 4 | VCC– | Negative supply rail - must be tied to ground in single-supply mode; establishes common-mode reference for all inputs. |
| 5 | 2IN+ | Non-inverting input of Amp B - electrically isolated from other amps; shares same bias network as 1IN+. |
| 6 | 2IN– | Inverting input of Amp B - identical electrical characteristics to 1IN–; used for feedback in inverting configurations. |
| 7 | 2OUT | Amplifier B output - independently buffered; no internal cross-coupling to 1OUT or 3OUT. |
| 8 | VCC+ | Positive supply rail - supplies all four amplifiers; requires 0.1 µF ceramic + 10 µF tantalum decoupling per rail. |
| 9 | 3OUT | Amplifier C output - rated for same output swing and drive capability as 1OUT and 2OUT. |
| 10 | 3IN– | Inverting input of Amp C - matched input bias and offset specs ensure consistent performance across all four channels. |
| 11 | 3IN+ | Non-inverting input of Amp C - supports rail-to-rail input common-mode range when VCC– = GND. |
| 12 | 4IN+ | Non-inverting input of Amp D - enables quad-channel signal conditioning without inter-channel gain mismatch. |
| 13 | 4IN– | Inverting input of Amp D - maintains ≤10 mV input offset voltage across temperature (0°C to 70°C). |
| 14 | 4OUT | Amplifier D output - completes quad configuration; pin-compatible with MC3303PW for drop-in replacement in commercial-temp designs. |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ±0.2 µA typical at 25°C - minimizes voltage error across high-impedance sensor bridges (e.g., 100 kΩ RTD circuits). |
| Internal frequency compensation | Stable unity-gain operation without external capacitors - eliminates layout sensitivity and reduces BOM count. |
| Short-circuit protection | ±45 mA output current limit - prevents device destruction during accidental output grounding or capacitive loading. |
| Wide temperature range | 0°C to 70°C operation - qualified for commercial-grade embedded systems including HVAC controllers and test equipment. |
| True differential input stage | Input common-mode range includes VCC– - enables direct connection of unipolar sensors (e.g., 4–20 mA receivers) without level-shifting resistors. |
Applications
| Industrial Sensor Signal Conditioning | DC Motor Speed Feedback Amplifier |
|---|---|

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 |
|---|---|---|---|
| MC3403DR | SOIC-14 package (8.65 mm × 3.91 mm); θJA = 86°C/W vs. 113°C/W for PW; identical electrical specs. | Better thermal performance in high-density layouts; larger footprint may conflict with space-constrained TSSOP designs. | Select MC3403DR when board real estate permits and thermal margin is critical; otherwise retain MC3403PWRE4 for compactness. |
| LM324DT | Higher input offset voltage (max 7 mV vs. 10 mV); wider temp range (−40°C to 105°C); same TSSOP-14 footprint. | Supports extended industrial environments; tighter offset benefits precision measurement where calibration is limited. | Choose LM324DT for −40°C operation or tighter offset tolerance; MC3403PWRE4 remains optimal for cost-sensitive 0°C–70°C commercial use. |
Compared with MC3403DR and LM324DT, the MC3403PWRE4 offers the smallest PCB footprint among functionally equivalent quad op-amps while maintaining TI's legacy reliability and exact µA741 compatibility - making it ideal for retrofitting legacy designs where board area is constrained but electrical behavior must remain unchanged.

FAQ
What is the maximum operating temperature range for the MC3403PWRE4?
The MC3403PWRE4 is characterized for operation from 0°C to 70°C ambient temperature. This commercial-grade specification aligns with its intended use in non-automotive, non-industrial-control applications such as test equipment, consumer electronics, and legacy instrumentation where extended temperature ranges are not required. The MC3303 variant supports −40°C to 85°C.
Does the MC3403PWRE4 require external compensation capacitors?
No, the MC3403PWRE4 features internal frequency compensation optimized for unity-gain stability. It operates reliably with no external components across all standard configurations (inverting, non-inverting, voltage follower) when loaded with ≤100 pF capacitance. Adding external compensation may degrade phase margin and increase settling time unnecessarily.
Can the MC3403PWRE4 operate from a single 3.3 V supply?
Yes, the MC3403PWRE4 supports single-supply operation down to 3 V. At 3.3 V, its output swing is guaranteed from VCC– (GND) to approximately 1.8 V, and input common-mode range extends to GND - enabling direct interfacing with 3.3 V microcontrollers and low-voltage sensors without level-shifting circuitry.
What is the thermal resistance (θJA) of the MC3403PWRE4 in its TSSOP-14 package?
The MC3403PWRE4 has a junction-to-ambient thermal resistance (θJA) of 113°C/W in the TSSOP-14 (PW) package, as specified in the official Texas Instruments datasheet. This value assumes standard JEDEC 2-layer board conditions; actual thermal performance improves with copper pour and thermal vias under the exposed pad region.
Is the MC3403PWRE4 pin-compatible with the MC3303PW?
Yes, the MC3403PWRE4 is pin-compatible with the MC3303PW - both use identical TSSOP-14 footprints and share the same pinout. However, the MC3303PW is rated for −40°C to 85°C operation and has tighter input offset voltage (8 mV max), while the MC3403PWRE4 is specified for 0°C to 70°C with 10 mV max offset.
