Product details
Overview
MC3303PW from Texas Instruments is a quadruple low-power operational amplifier optimized for single-supply operation from 3 V to 36 V or dual supplies up to ±18 V. It features true differential inputs, Class AB output stage, internal frequency compensation, and guaranteed operation from –40°C to +85°C. Its 8 mV max input offset voltage and 2.8–7 mA total supply current support precision analog signal conditioning in industrial sensor interfaces and power supply monitoring circuits.
For engineers reviewing the MC3303PW datasheet, MC3303PW pinout, MC3303PW application, or MC3303PW equivalent, this page delivers verified specifications, TSSOP-14 package details, real-world use cases, and two validated alternative parts - all grounded in TI's SLOS101C production data sheet and official packaging addendum.
Technical Context
The MC3303PW implements four independent op-amps per die with fully differential input stages referenced to VCC–, enabling rail-to-rail common-mode input down to the negative supply. Each amplifier uses internal dominant-pole compensation for unity-gain stability without external components.
Its Class AB output stage delivers ±10 V peak swing into 2 kΩ at ±15 V supplies, while maintaining low quiescent current (≤7 mA total) and short-circuit protection. Input bias current remains below –1 µA over full temperature range, supporting high-impedance source interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | Single: 3 V to 36 V; Dual: ±2.5 V to ±15 V - supports wide-input industrial power rails and battery-powered systems. |
| Input Offset Voltage (max) | 8 mV at 25°C - enables accurate DC-coupled amplification without trimming in cost-sensitive designs. |
| Input Bias Current (max) | –1 µA over –40°C to +85°C - preserves signal integrity when driving high-impedance sensors or filters. |
| Unity-Gain Bandwidth | 1 MHz - sufficient for anti-aliasing, active filtering, and slow-control-loop compensation. |
| Slew Rate | 0.6 V/µs - limits distortion in medium-speed signal conditioning without excessive power draw. |
| Common-Mode Input Range | VCC– to (VCC+ – 2 V) - allows direct sensing of signals referenced to ground in single-supply configurations. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and automotive under-hood environments. |

Applications
| Industrial Sensor Signal Conditioning | DC Motor Current Monitoring |
|---|---|
|
Use Scenario: Amplifying low-level outputs from RTDs, strain gauges, or pressure transducers in PLC analog input modules. IC Role / Device Role / Timing Role: Quad op-amp configured as instrumentation amplifier front-end, filter stage, and reference buffer. Use Value: 8 mV max VIO and –40°C to +85°C rating ensure measurement accuracy across factory-floor temperature swings without calibration drift. |
Use Scenario: Sensing shunt resistor voltage in H-bridge motor drivers to detect stall or overload conditions. IC Role / Device Role / Timing Role: Single amplifier used as differential current-sense amplifier; others provide supply rail monitoring and fault logic conditioning. Use Value: Rail-to-rail input capability (VCC– to VCC+–2 V) allows direct connection to shunt placed on low-side, eliminating level-shifters. |
| Programmable Power Supply Feedback | Multi-Channel Data Acquisition Front-End |
|
Use Scenario: Regulating output voltage/current in benchtop or embedded programmable power supplies using DAC-controlled setpoints. IC Role / Device Role / Timing Role: One op-amp acts as error amplifier comparing DAC output to sensed output; others condition auxiliary signals (temp, fan speed). Use Value: 1 MHz unity-gain bandwidth ensures stable loop response up to ~100 kHz control bandwidth with adequate phase margin. |
Use Scenario: Simultaneous conditioning of four independent analog sensor channels before ADC sampling in environmental monitoring nodes. IC Role / Device Role / Timing Role: Each amplifier independently configured as anti-aliasing filter, gain stage, or DC offset adjuster. Use Value: ≥120 dB crosstalk attenuation prevents channel-to-channel interference in high-resolution (16-bit+) acquisition systems. |
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 |
|---|---|---|---|
| MC3303N | PDIP-14 package; θJA = 80°C/W vs. 113°C/W for PW; same electrical specs and temp range. | Better thermal performance in through-hole prototyping or low-volume industrial assemblies; not suitable for automated SMT lines. | Select MC3303N for hand-soldered evaluation or legacy board compatibility; choose MC3303PW for high-density PCBs requiring fine-pitch surface mount. |
| MC3403PW | Same TSSOP-14 package but rated 0°C to +70°C; 10 mV max VIO vs. 8 mV; otherwise identical AC/DC specs. | Valid for commercial-temperature consumer or office equipment where extended temp range is unnecessary. | Choose MC3403PW only if ambient operating temperature stays within 0–70°C and 2 mV higher offset is acceptable; MC3303PW remains preferred for industrial use. |
Compared with MC3303N and MC3403PW, the MC3303PW uniquely combines industrial temperature qualification (–40°C to +85°C), TSSOP-14 miniaturization, and 8 mV input offset - making it the optimal choice for space-constrained, thermally demanding applications where long-term DC stability is critical.

FAQ
What is the maximum operating temperature range for the MC3303PW?
The MC3303PW is characterized for operation from –40°C to +85°C, as confirmed in TI's SLOS101C datasheet Section "Recommended Operating Conditions". This industrial temperature grade makes the MC3303PW suitable for deployment in harsh environments such as factory floors, outdoor enclosures, and automotive under-hood applications where ambient temperatures exceed commercial-grade limits.
Does the MC3303PW require external compensation capacitors?
No, the MC3303PW includes internal frequency compensation and is stable at unity gain without external components, as stated in the "Features" section of the SLOS101C datasheet. This eliminates the need for external compensation networks, simplifying design and reducing bill-of-materials count in applications like voltage followers and basic gain stages.
Is the MC3303PW pin-compatible with the original Motorola MC3303?
Yes, the MC3303PW is explicitly designed to be interchangeable with the Motorola MC3303, as documented in the SLOS101C datasheet introduction. Both share identical pinout, electrical specifications, and functional behavior - enabling drop-in replacement in legacy designs without PCB or schematic modifications.
What is the typical supply current consumption of the MC3303PW?
The MC3303PW draws 2.8–7 mA total quiescent supply current across its four amplifiers, depending on supply voltage and load conditions, per the "Electrical Characteristics" table in SLOS101C. At VCC+ = 14 V and VCC– = 0 V, typical ICC is 2.8 mA - less than half that of the µA741, supporting energy-efficient system design.
Can the MC3303PW operate from a single 5-V supply?
Yes, the MC3303PW supports single-supply operation from 3 V to 36 V, including 5 V. At VCC+ = 5 V and VCC– = 0 V, its output swings to within 1.7 V of the rails (i.e., 0 V to 3.3 V), and input common-mode range extends to VCC–, enabling direct interface with microcontroller ADCs and digital logic without level-shifting circuitry.
