AD548KNZ

产品概述

The AD548KNZ is a low power precision monolithic Operational Amplifier offers both low bias current (10pA maximum, warmed up) and low quiescent current (200µA maximum) and is fabricated with ion-implanted FET and laser wafer trimming technologies. Input bias current is guaranteed over the AD548’s entire common-mode voltage range. The economical J grade has a maximum guaranteed input offset voltage of less than 2mV and an input offset voltage drift of less than 20µV/°C. This level of DC precision is achieved utilizing Analog’s laser wafer drift trimming process. The combination of low quiescent current and low offset voltage drift minimizes changes in input offset voltage due to self-heating effects. The AD548 is recommended for any dual supply op amp application requiring low power and excellent DC and AC performance. In applications such as battery-powered, precision instrument front ends and CMOS DAC buffers.

• Enhanced replacement for LF441 and TL061
• Indefinite output short-circuit duration
• 200µA Maximum quiescent current
• 500mW Internal power dissipation
