RC4558D

RC4558D Description

The RC4558D from Texas Instruments is a dual general-purpose operational amplifier housed in an 8-SOIC package, designed for precision analog applications. This ROHS3 Compliant and REACH Unaffected device operates over a wide supply voltage range of 10V to 30V, making it versatile for various circuit designs. With a gain bandwidth product of 3 MHz and a slew rate of 1.7V/µs, it delivers stable performance in signal conditioning, filtering, and amplification tasks. The low input bias current (150 nA) and moderate input offset voltage (500 µV) ensure accuracy in sensitive applications. Its Last Time Buy status indicates limited availability, making it critical for legacy system maintenance.

• Dual-channel architecture (2 circuits) for space-efficient designs.
• Low power consumption: 2.5mA per channel supply current.
• High output drive capability: 10 mA per channel for robust signal transmission.
• Wide operating temperature range: 0°C to 70°C, suitable for industrial environments.
• Surface-mount (SOIC) packaging for compact PCB integration.
• Differential output for noise-resistant signal processing.
• MSL 1 (Unlimited) moisture sensitivity, ensuring reliability in storage and assembly.

RC4558D Applications

The RC4558D excels in:

• Active filters and audio preamplifiers due to its low noise and stable gain.
• Sensor signal conditioning (e.g., thermocouples, strain gauges) leveraging its precision offset performance.
• Industrial control systems requiring robust operation under varying voltages.
• Legacy equipment maintenance where drop-in replacements are needed.
• Portable instrumentation benefiting from its low power draw and small footprint.

Conclusion of RC4558D
