LM324ADR

LM324ADR Description

The LM324ADR from Texas Instruments is a general-purpose quad operational amplifier designed for low-power, wide-voltage-range applications. Packaged in a 14-SOIC surface-mount format and supplied in Tape & Reel (TR), it is optimized for cost-sensitive and space-constrained designs. With a supply voltage range of 3V to 30V, it supports both single and dual-supply operations, making it highly versatile. The device features four independent op-amps in a single package, reducing PCB footprint and BOM complexity. Its low input bias current (15 nA) and moderate slew rate (0.5V/µs) ensure stable performance in precision and general-purpose analog circuits.

LM324ADR Features

• Wide Supply Range (3V–30V): Suitable for battery-powered and industrial applications.
• Low Power Consumption: Only 1.4mA per channel, ideal for energy-efficient designs.
• High Output Drive (30mA/channel): Capable of driving moderate loads directly.
• Low Input Offset Voltage (2mV): Enhances accuracy in signal conditioning.
• Gain Bandwidth Product (1.2MHz): Balances speed and stability for general-purpose use.
• Robust Packaging: MSL1 (Unlimited) moisture sensitivity ensures easy handling.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards.
