OP Amps, Buffer Amps ICs

LM358AST Description

The LM358AST from STMicroelectronics is a dual-channel general-purpose operational amplifier designed for automotive-grade applications, offering robust performance across a wide operating temperature range of 0°C to 70°C. Packaged in a surface-mount 8-MiniSO format and supplied in Tape & Reel (TR), it is optimized for high-volume production. With a supply voltage range of 3V to 30V, this IC delivers low power consumption (700µA per channel) while maintaining excellent signal integrity. Its 1.1 MHz gain bandwidth product and 0.6V/µs slew rate make it suitable for precision analog signal processing.

LM358AST Features

• Automotive-Grade Reliability: Compliant with stringent automotive standards, ensuring durability in harsh environments.
• Low Input Bias Current (20 nA): Minimizes errors in high-impedance circuits.
• Wide Supply Range (3V–30V): Supports both single and dual-rail configurations.
• High Output Current (40 mA per channel): Drives loads directly without additional buffering.
• Low Offset Voltage (1 mV): Enhances accuracy in DC-coupled applications.
• ROHS3 & REACH Compliant: Environmentally friendly and suitable for global markets.

LM358AST Applications

• Sensor Signal Conditioning: Ideal for amplifying low-level signals from thermocouples, pressure sensors, or strain gauges.
