LM833DR

LM833DR Description

The LM833DR from Texas Instruments is a high-performance, dual-channel audio operational amplifier designed for precision audio applications. Packaged in an 8-SOIC surface-mount configuration and supplied in Tape & Reel (TR), it is optimized for low-noise, high-fidelity signal processing. With a 16 MHz gain bandwidth product and a 7V/µs slew rate, the LM833DR ensures excellent dynamic response, making it ideal for audio amplification, filtering, and signal conditioning. Its low input bias current (300 nA) and low offset voltage (150 µV) contribute to superior signal accuracy, while the wide supply voltage range (10V to 36V) provides flexibility in various power configurations.

LM833DR Features

• Dual-Channel Design: Two independent amplifiers in a single package, reducing board space and cost.
• Low Noise & Distortion: Optimized for high-fidelity audio applications with minimal signal degradation.
• High Slew Rate (7V/µs): Ensures fast transient response for dynamic audio signals.
• Wide Supply Range (10V–36V): Compatible with diverse power supplies, including single and split-rail configurations.
• Low Power Consumption (2.05mA per channel): Balances performance and energy efficiency.
• Robust Output Drive (37mA per channel): Capable of driving low-impedance loads.
• RoHS3 & REACH Compliant: Meets environmental and safety standards for global use.

LM833DR Applications

The LM833DR excels in professional audio equipment, active filters, preamplifiers, and high-end consumer audio systems.
