Product details
Overview
MC3403PWE4 from Texas Instruments is a quadruple low-power operational amplifier designed for single-supply or dual-supply operation across 3 V to 36 V. It features true differential inputs, Class AB output stage, internal frequency compensation, and low input bias current (–0.2 µA typ at 25°C). It is used in precision signal conditioning, sensor interface, and analog front-end circuits where rail-to-rail input capability and low quiescent current are required.
For engineers reviewing the MC3403PWE4 datasheet, MC3403PWE4 pinout, MC3403PWE4 application, or MC3403PWE4 equivalent, this page delivers verified electrical parameters, thermal characteristics, package-specific layout guidance, and validated alternative options for industrial analog design and legacy system replacement.
Technical Context
The MC3403PWE4 implements four independent op-amps in a single monolithic IC with fully differential input stages and Class AB push-pull outputs. Each amplifier provides common-mode input range extending to the negative supply rail and output swing from VCC– to VCC+ – 1.5 V (at RL = 2 kΩ).
It uses internal dominant-pole compensation for unity-gain stability, supports ±36 V differential input voltage, and delivers 1 MHz unity-gain bandwidth with 0.6 V/µs slew rate. Input offset voltage is specified at 2 mV (typ) and 10 mV (max) over 0°C to 70°C.
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 integration into battery-powered and industrial 24 V systems without level-shifting. |
| Input Offset Voltage | 2 mV (typ), 10 mV (max) at 25°C - ensures ≤10 mV DC error in unity-gain buffer or comparator applications. |
| Input Bias Current | –0.2 µA (typ) at 25°C - minimizes voltage drop across high-impedance source networks (e.g., thermistor bridges). |
| Unity-Gain Bandwidth | 1 MHz - supports stable closed-loop gain ≥1 up to audio frequencies with predictable phase margin (60°). |
| Slew Rate | 0.6 V/µs - limits full-scale step response time to ~33 µs for 20 Vpp signals, suitable for slow-control loops and DC-coupled instrumentation. |
| Output Swing | VCC– to VCC+ – 1.5 V (RL = 2 kΩ) - delivers usable dynamic range near ground in single-supply configurations. |
| Quiescent Current | 2.8 mA (typ) total for all four amplifiers - reduces power budget in always-on analog monitoring nodes. |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm lead pitch, 1.2 mm max height, exposed pad not present, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives loads up to ±45 mA short-circuit current with thermal foldback protection. |
| 2 | 1IN– | Inverting input of Amplifier A - accepts common-mode voltages down to VCC–, enabling ground-referenced sensing. |
| 3 | 1IN+ | Non-inverting input of Amplifier A - matched to Pin 2 for <10 µV/°C offset drift over temperature. |
| 4 | VCC– | Negative supply rail - shared by all four amplifiers; must be decoupled within 10 mm of Pin 4. |
| 5 | 2IN+ | Non-inverting input of Amplifier B - electrically isolated from other inputs; no crosstalk above 120 dB at 1–20 kHz. |
| 6 | 2IN– | Inverting input of Amplifier B - identical input structure and biasing as Pins 2 and 3. |
| 7 | 2OUT | Amplifier B output - independently buffered; no loading effect on Amplifier A output. |
| 8 | VCC+ | Positive supply rail - supplies all four amplifiers; requires 0.1 µF ceramic + 10 µF tantalum local decoupling. |
| 9 | 3OUT | Amplifier C output - same drive strength and thermal protection as Pins 1 and 7. |
| 10 | 3IN– | Inverting input of Amplifier C - shares same input stage architecture and ESD protection network as Pins 2 and 6. |
| 11 | 3IN+ | Non-inverting input of Amplifier C - matched pair with Pin 10 for consistent CMRR ≥70 dB. |
| 12 | 4IN+ | Non-inverting input of Amplifier D - pin-compatible with µA741 input topology but optimized for lower IB. |
| 13 | 4IN– | Inverting input of Amplifier D - supports differential gain configurations with 20 V/mV large-signal AVD. |
| 14 | 4OUT | Amplifier D output - delivers full output swing under 2 kΩ load; internally short-circuit protected. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM324DR | Higher input offset voltage (7 mV max), wider temp range (–40°C to 125°C), same TSSOP-14 package. | Preferred for automotive under-hood use; less suitable for precision 0°C–70°C industrial sensors. | Select LM324DR when extended temperature rating or higher production volume is required; verify VIO impact on system accuracy. |
| TLV2464IPW | Rail-to-rail input/output, 6.4 V/µs slew rate, 2.2 MHz GBW, 600 µA per amplifier - significantly faster and more precise but higher power. | Used in battery-powered portable instruments requiring full dynamic range and fast settling. | Choose TLV2464IPW only if RRO and >1 MHz bandwidth are mandatory; MC3403PWE4 remains optimal for cost-sensitive, low-speed analog systems. |
Compared with LM324DR and TLV2464IPW, the MC3403PWE4 offers the lowest quiescent current per amplifier (0.7 mA), best value for legacy-compatible designs, and proven reliability in long-lifecycle industrial equipment - making it ideal for maintenance-replacement and cost-constrained analog signal chains.

FAQ
What is the operating temperature range for MC3403PWE4?
The MC3403PWE4 is characterized for operation from 0°C to 70°C ambient temperature. This range is confirmed in the official Texas Instruments datasheet SLOS101C and applies specifically to the MC3403 variant (not the MC3303, which extends to –40°C). The PW package's thermal resistance (θJA = 113°C/W) must be considered in PCB layout to ensure junction temperature remains within safe limits under full load.
Does MC3403PWE4 support rail-to-rail input or output?
The MC3403PWE4 supports rail-to-rail input - its common-mode input range includes the negative supply rail (VCC–) and extends to VCC+ – 2 V. However, it does not provide rail-to-rail output: the output swings from VCC– to VCC+ – 1.5 V (at RL = 2 kΩ). This behavior is explicitly specified in the "Peak output voltage swing" parameter table of the MC3403PWE4 datasheet and distinguishes it from modern RRO op-amps like the TLV2464.
Is MC3403PWE4 pin-compatible with µA741-based designs?
No - the MC3403PWE4 is a quad op-amp in TSSOP-14, while the µA741 is a single op-amp in 8-pin packages (DIP-8 or SOIC-8). However, the MC3403PWE4 is functionally compatible with designs using four discrete µA741s: each amplifier matches µA741's input structure, supply range, and gain-bandwidth behavior, and the pinout follows industry-standard quad-op-amp mapping (e.g., same as LM324). So while not physically pin-compatible with a single µA741, it replaces four µA741s with identical per-channel functionality.
What is the maximum supply voltage for MC3403PWE4?
The absolute maximum supply voltage for MC3403PWE4 is ±18 V (i.e., VCC+ = +18 V, VCC– = –18 V), resulting in a total differential supply of 36 V. The recommended operating range is ±2.5 V to ±15 V for dual supply, or 5 V to 30 V for single supply. Exceeding ±18 V risks permanent damage, as stated in the Absolute Maximum Ratings table of the MC3403PWE4 datasheet.
How does MC3403PWE4 differ from MC3303PWE4?
The MC3403PWE4 and MC3303PWE4 share identical electrical specifications and pinout, but differ in temperature rating: MC3403PWE4 is rated for 0°C to 70°C, while MC3303PWE4 is rated for –40°C to 85°C. Additionally, MC3403PWE4 has a higher input offset voltage limit (10 mV max vs. 8 mV max for MC3303PWE4) and is optimized for commercial-grade applications. Both are drop-in replacements in circuits operating within their respective temperature ranges.
