Product details
Overview
MC3303DR from Texas Instruments is a quadruple low-power operational amplifier IC designed for precision analog signal conditioning in single- or dual-supply systems. It delivers 1 MHz unity-gain bandwidth, 0.6 V/µs slew rate, ±10 mA short-circuit output current, and operates across –40°C to 85°C with input offset voltage ≤8 mV at 25°C. It is widely used in sensor interface circuits requiring rail-to-rail-compatible input stage and stable DC gain.
For engineers reviewing the MC3303DR datasheet, MC3303DR pinout, MC3303DR application, or MC3303DR equivalent, this page provides verified electrical specifications, SOIC-14 package details, thermal and supply-voltage sensitivity data, and validated alternative options for industrial temperature-range op-amp replacement.
Technical Context
The MC3303DR implements a true differential input stage with Class AB output, enabling operation from single supplies (3 V to 36 V) or split supplies (±2.5 V to ±15 V), with common-mode input range extending to the negative rail. Its internal frequency compensation ensures stability without external components across all four amplifiers.
Each amplifier features low input bias current (–0.5 µA typ), high common-mode rejection (70–90 dB), and 120 dB crosstalk attenuation between channels - critical for multi-channel instrumentation where channel isolation and DC accuracy are essential.
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 sensors and battery-powered systems. |
| Unity-Gain Bandwidth | 1 MHz - sufficient for anti-aliasing, active filtering, and medium-speed transducer signal conditioning. |
| Slew Rate | 0.6 V/µs - enables clean 10 kHz sine-wave output at ±10 V swing into 2 kΩ load. |
| Input Offset Voltage | ≤8 mV at 25°C (max), ≤12 mV over full temperature range - defines baseline DC error in precision gain stages. |
| Common-Mode Input Range | VCC– to (VCC+ – 2 V) - allows direct interfacing with ground-referenced sensors and single-supply ADC drivers. |
| Output Voltage Swing | VCC– to (VCC+ – 1.5 V) at RL = 2 kΩ - delivers >90% of rail-to-rail dynamic range for efficient power utilization. |
| Quiescent Current | 2.8–7 mA total (all four amps) - enables low-power multi-amplifier designs without thermal derating. |
Pinout & Package
MC3303DR is housed in a 14-pin plastic small-outline integrated circuit (SOIC-D) package, 8.75 mm × 4.0 mm footprint, 1.75 mm max height, RoHS-compliant NIPDAU lead finish, MSL Level-1, tape-and-reel packaging (2500 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives loads up to ±10 mA with <1% crossover distortion. |
| 2 | 1IN– | Inverting input of Amp A - accepts signals down to VCC–, supports summing junctions and feedback networks. |
| 3 | 1IN+ | Non-inverting input of Amp A - high-impedance node (≥0.3 MΩ) for sensor voltage sensing. |

| 5 | 2IN+ | Non-inverting input of Amp B - electrically isolated from other inputs; enables independent channel configuration. |
| 6 | 2IN– | Inverting input of Amp B - supports differential input configurations with matched impedance routing. |
| 7 | 2OUT | Amplifier B output - identical drive capability and AC performance as Pin 1. |
| 8 | VCC+ | Positive supply rail - powers all four amplifiers; decoupling recommended within 1 cm. |
| 9 | 3OUT | Amplifier C output - fully functional channel with same specs; enables 3-channel signal processing in one IC. |
| 10 | 3IN– | Inverting input of Amp C - supports cascaded gain stages or multi-stage filtering topologies. |
| 11 | 3IN+ | Non-inverting input of Amp C - referenced to VCC–; usable for level-shifting or reference-biased amplification. |
| 12 | 4IN+ | Non-inverting input of Amp D - enables fourth independent analog path without board area penalty. |
| 13 | 4IN– | Inverting input of Amp D - supports unity-gain buffer or inverting amplifier configurations. |
| 14 | 4OUT | Amplifier D output - completes quad functionality; crosstalk attenuation ≥120 dB minimizes inter-channel coupling. |
Key Features
| Feature | Design Value |
|---|---|
| True differential input stage | Enables accurate DC-coupled amplification of low-level signals referenced to VCC–, eliminating need for level-shifting circuitry. |
| Class AB output stage | Delivers low-distortion (1% typ) output swing to within 1.5 V of VCC+ and to VCC–, supporting wide-dynamic-range applications. |
| Internal frequency compensation | Guarantees unity-gain stability with no external capacitor required - simplifies layout and reduces BOM count. |
| Short-circuit protection | Withstands indefinite output shorts to VCC+ or VCC– without latch-up or permanent damage - enhances system reliability. |
| Low input bias current | –0.5 µA typical at 25°C - minimizes voltage error across high-impedance source networks (e.g., thermocouples, pH electrodes). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC3403DR | Same architecture and pinout, but rated for 0°C to 70°C only; input offset voltage max 10 mV (vs. 8 mV for MC3303DR). | Not suitable for extended-temperature industrial or automotive under-hood use. | Select MC3403DR only when ambient operating temperature remains within commercial range and cost is prioritized over temperature margin. |
| LM324DR | Higher input offset voltage (up to 7 mV typ), lower CMRR (65 dB min), and slower slew rate (0.4 V/µs); not characterized for –40°C operation. | Lacks guaranteed performance below 0°C; requires design revalidation for cold-environment deployments. | Choose LM324DR only for non-critical consumer-grade applications where extended temperature range and precision are not required. |
Compared with MC3403DR and LM324DR, the MC3303DR uniquely combines industrial temperature rating (–40°C to 85°C), sub-8-mV input offset, and full quad-channel specification compliance - making it the only option qualified for mission-critical analog signal chains in harsh environments.

FAQ
What is the operating temperature range of the MC3303DR?
The MC3303DR is specified for operation from –40°C to +85°C, making it suitable for industrial environments including factory floors, outdoor monitoring systems, and automotive under-dash applications. This extended range is confirmed in the official TI datasheet SLOS101C and distinguishes it from the commercial-grade MC3403DR.
Is the MC3303DR pin-compatible with the µA741-based quad op-amp designs?
Yes, the MC3303DR uses the industry-standard SOIC-14 pinout shared with µA741-family quads, including identical assignments for VCC+, VCC–, and all eight input/output terminals. No PCB changes are required when replacing legacy µA741-based quad solutions, provided supply voltage and loading remain within MC3303DR specifications.
Does the MC3303DR require external compensation capacitors?
No, the MC3303DR features internal frequency compensation optimized for unity-gain stability. It operates reliably with no external components across its full specified supply range and load conditions - a key advantage over earlier op-amps like the µA741 that require external compensation networks.
What is the maximum output current capability of each amplifier in the MC3303DR?
Each amplifier in the MC3303DR delivers ±10 mA short-circuit output current (typical), with guaranteed ±45 mA peak during transient overload. This enables direct driving of moderate-impedance loads such as LED indicators, small relays, or ADC input buffers without external transistor buffering.
Can the MC3303DR operate from a single 5-V supply?
Yes, the MC3303DR supports single-supply operation from 3 V to 36 V. At VCC+ = 5 V and VCC– = 0 V, it delivers a peak output swing of 3.3 V (VCC+ – 1.7 V) into 10 kΩ, with input common-mode range extending to ground - ideal for interfacing with 5-V microcontrollers and ADCs.
