Product details
Overview
MC3303PWR 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, features 8 mV max input offset voltage at 25°C, and is rated for –40°C to 85°C industrial temperature range - used in sensor signal conditioning, power supply feedback, and analog front-end circuits.
For engineers reviewing the MC3303PWR datasheet, MC3303PWR pinout, MC3303PWR application, or MC3303PWR equivalent, this page provides verified electrical parameters, thermal and packaging data, functional role in analog signal chains, and validated alternative options for design continuity and sourcing resilience.
Technical Context
The MC3303PWR implements four independent op-amps per package, each with a common-mode input range extending to the negative rail and output swing reaching VCC– to VCC+ – 1.5 V under load. Its Class AB output stage enables stable drive into 2 kΩ loads while maintaining low quiescent current (2.8 mA typical).
Internal frequency compensation ensures unity-gain stability without external components; short-circuit protection and low input bias current (–0.2 µA typ) support robust operation in unregulated or battery-powered systems. The device shares pinout and functional compatibility with Motorola MC3303 and TI's own MC3403 family variants.
Key Specifications

|---|---|
| Supply Voltage Range | Single: 3 V to 36 V; Dual: ±2.5 V to ±15 V - supports wide-input industrial power rails and battery-backed systems. |
| Input Offset Voltage | 8 mV max at 25°C, 12 mV max over full temperature range - sets DC accuracy limit in precision gain stages. |
| Output Swing | VCC– to VCC+ – 1.5 V into 2 kΩ - enables rail-to-rail compatible sensing near ground in single-supply configurations. |
| Unity-Gain Bandwidth | 1 MHz - sufficient for DC–100 kHz signal conditioning, filtering, and transducer amplification. |
| Slew Rate | 0.6 V/µs - limits large-signal transient response but ensures stability with capacitive loads up to 100 pF. |
| Quiescent Current | 2.8 mA typical total for all four amplifiers - enables low-power operation in always-on monitoring circuits. |

TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 1.2 mm max height, 0.65 mm lead pitch, exposed pad not electrically connected, RoHS-compliant NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives external load or next stage; limited to VCC– to VCC+ – 1.5 V swing. |
| 2 | 1IN– | Inverting input of Amp A - high-impedance node; bias current –0.2 µA typ affects high-Z source matching. |
| 3 | 1IN+ | Non-inverting input of Amp A - referenced to common-mode range including VCC–; enables ground-referenced sensing. |
| 4 | VCC– | Negative supply rail - shared by all four amplifiers; must be stable and low-noise for CMRR integrity. |
| 5 | 2IN+ | Non-inverting input of Amp B - identical electrical behavior to Pin 3; supports multi-channel parallel processing. |
| 6 | 2IN– | Inverting input of Amp B - matches Pin 2 performance; allows matched differential pair implementation. |
| 7 | 2OUT | Amplifier B output - electrically isolated from Pin 1; enables independent gain paths without crosstalk (120 dB). |
| 8 | VCC+ | Positive supply rail - powers all amplifiers; decoupling capacitor required within 1 cm for stability. |
| 9 | 3OUT | Amplifier C output - same drive capability as Pins 1 and 7; supports three-stage signal chain or redundancy. |
| 10 | 3IN– | Inverting input of Amp C - matches Pin 2/6; maintains consistent input impedance across all channels. |
| 11 | 3IN+ | Non-inverting input of Amp C - identical to Pins 3 and 5; enables synchronized multi-sensor interface. |
| 12 | 4IN+ | Non-inverting input of Amp D - completes quad configuration; supports simultaneous analog acquisition. |
| 13 | 4IN– | Inverting input of Amp D - matches prior inverting inputs; allows uniform feedback network design. |
| 14 | 4OUT | Amplifier D output - fully independent; enables fourth channel without shared loading effects. |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | –0.2 µA typical enables high-impedance sensor interfacing (e.g., thermistors, pH electrodes) without significant error. |
| True Differential Input Stage | Common-mode range includes VCC–, allowing ground-referenced inputs in single-supply systems without level-shifting. |
| Internal Frequency Compensation | Guarantees unity-gain stability with no external components - reduces BOM count and layout sensitivity. |

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 |
|---|---|---|---|
| MC3403PWR | Same pinout and architecture, but rated 0°C to 70°C and 10 mV max VIO at 25°C - higher offset, narrower temp range. | Restricted to commercial-grade equipment; unsuitable for extended-temperature industrial deployments. | Select MC3403PWR only when cost is primary and operating environment stays within 0–70°C. |
| LM324PWR | Pin-compatible quad op-amp with 2 mV max VIO, 1.2 MHz GBW, and 0.5 V/µs slew rate - tighter offset, faster, lower power. | Superior DC precision and bandwidth; however, LM324 lacks short-circuit protection and has lower output drive. | Choose LM324PWR where accuracy and speed outweigh fault tolerance; verify load current limits in final design. |
Compared with MC3303PWR, MC3403PWR trades temperature range and offset for legacy compatibility, while LM324PWR offers modern performance at the cost of robustness - MC3303PWR remains optimal for ruggedized, wide-supply, fault-tolerant analog signal chains.

FAQ
What is the maximum operating supply voltage for MC3303PWR?
The MC3303PWR supports a maximum total supply voltage of 36 V - either as single supply (3 V to 36 V) or dual supply (±2.5 V to ±15 V). Exceeding ±18 V on either rail violates absolute maximum ratings and risks permanent damage. Derating is recommended above 30 V for long-term reliability.
Does MC3303PWR include internal frequency compensation?
Yes, the MC3303PWR integrates internal frequency compensation, enabling stable unity-gain operation without external capacitors. This is confirmed in the datasheet's "Features" section and verified by its 1 MHz unity-gain bandwidth and 60° phase margin at CL = 200 pF.
What is the input common-mode voltage range of MC3303PWR?
The MC3303PWR features a true differential input stage with common-mode range extending from VCC– to VCC+ – 2 V. At VCC+ = 15 V and VCC– = 0 V, this yields 0 V to +13 V - allowing ground-referenced inputs in single-supply configurations without level-shifting circuitry.
Is MC3303PWR pin-compatible with MC3403PWR?
Yes, MC3303PWR and MC3403PWR share identical TSSOP-14 pinout, electrical architecture, and functional behavior. The only differences are temperature grade (–40°C to 85°C vs. 0°C to 70°C) and input offset voltage specification (8 mV vs. 10 mV max at 25°C).
What thermal considerations apply to MC3303PWR in TSSOP-14 package?
The MC3303PWR in PW package has θJA = 113°C/W. At 7 mA max ICC and 30 V supply, worst-case power dissipation is ~210 mW, resulting in ~24°C junction rise above ambient. Use of PCB copper pour under the exposed pad (if present) and thermal vias improves heat transfer, though the PW package does not feature a thermal pad.
