OP482GS

OP482GS Description

The OP482GS from Analog Devices Inc. is a high-performance, quad-channel JFET-input operational amplifier housed in a 14-SOIC surface-mount package. Designed for precision applications, it offers a low input bias current (3 pA) and low input offset voltage (200 µV), ensuring accurate signal conditioning. With a wide supply voltage range (9V to 36V) and low supply current (210µA per channel), it balances power efficiency with robust performance. The 4 MHz gain bandwidth product and 9V/µs slew rate make it suitable for high-speed signal processing. Though marked Obsolete, it remains a reliable choice for legacy designs requiring stable, low-noise amplification.
