Yes — for the OPA4391PWR 14‑TSSOP, each pin belongs to exactly one functional group:
  • Power
    • Pin 4: V+
    • Pin 11: V−
  • Channel A
    • Pin 1: OUT A
    • Pin 2: −IN A
    • Pin 3: +IN A
  • Channel B
    • Pin 5: +IN B
    • Pin 6: −IN B
    • Pin 7: OUT B
  • Channel C
    • Pin 8: OUT C
    • Pin 9: −IN C
    • Pin 10: +IN C

OPA4391PWR

OPA4391PWR thumbnail
Standard (General Purpose) Amplifier 4 Circuit Push-Pull, Rail-to-Rail 14-TSSOP
The OPA4391PWR is a precision quad operational amplifier designed for low-noise, high-speed signal conditioning in a wide range of analog applications. It integrates four independent amplifier channels within a single compact package, making it suitable for space-constrained designs that require consistent performance across multiple signal paths. The device offers a combination of low offset voltage, wide bandwidth, and fast slew rate, enabling accurate amplification of both small and rapidly changing signals. It is commonly used in instrumentation, data acquisition systems, active filtering, and audio signal processing where stability and signal integrity are critical.
Functional Overview The device consists of four matched operational amplifiers that share common power supply connections while maintaining independent signal paths. Each amplifier is capable of operating in standard configurations such as inverting, non-inverting, differential, and buffer modes. The architecture supports rail-to-rail output swing, allowing efficient use of the available supply voltage. Internal design optimization ensures low distortion and stable operation across a broad range of load conditions.
Electrical Characteristics The OPA4391PWR is optimized for low input offset voltage and low input bias current, contributing to high accuracy in precision applications. It features wide gain bandwidth and a high slew rate, supporting fast transient response and high-frequency operation. The amplifier maintains low noise performance, making it suitable for sensitive analog front-end designs. Power consumption is balanced to provide efficient operation without compromising dynamic performance.
Operating Conditions The device operates over a wide supply voltage range, supporting both single-supply and dual-supply configurations. It is designed to function reliably across an extended temperature range, ensuring consistent performance in varying environmental conditions. Proper decoupling and layout practices are recommended to maintain stability and minimize noise coupling.
Package and Mechanical Characteristics The OPA4391PWR is provided in a compact surface-mount package suitable for automated assembly processes. The package is designed to facilitate efficient thermal dissipation and reliable electrical connections. Pin configuration allows straightforward integration into standard PCB layouts for quad operational amplifiers.
Applications This device is intended for use in precision analog circuits including signal conditioning, sensor interfaces, active filters, audio amplification, and data acquisition systems. Its combination of low noise, high speed, and multi-channel integration makes it well-suited for both industrial and consumer electronics applications.
Design Considerations Careful PCB layout is recommended to optimize performance, including short signal paths, proper grounding, and adequate power supply decoupling. Input and output traces should be routed to minimize interference and crosstalk between channels. Thermal management should be considered in high-performance or high-density designs to ensure long-term reliability.
