AD8604DRZ

AD8604DRZ Description

The AD8604DRZ from Analog Devices Inc. is a precision, low-power, quad CMOS operational amplifier designed for high-performance signal conditioning applications. Housed in a 14-SOIC package, it integrates four independent amplifiers with DigiTrim® technology for minimal input offset voltage (1.3 mV max) and ultra-low input bias current (0.2 pA). Operating over a 2.7V to 5.5V supply range, it delivers a gain bandwidth product of 8.4 MHz and a slew rate of 6V/µs, making it suitable for high-speed, low-noise systems. With a supply current of 750µA per channel and 50 mA output drive capability, it balances efficiency and performance.
