MAX409BCSA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX409BCSA+ is a single-channel operational amplifier from the MAX406/MAX407/MAX409 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 1.25V to 5V or 2.5V to 10V. Key electrical parameters include a gain-bandwidth product of 150 kHz, a slew rate of 80 mV/µs, an input offset voltage of 2 mV, and an input bias current of 10 pA. The device draws 1.2 mA of operating supply current and provides a maximum output current of 600 µA per channel. It features a common-mode rejection ratio of 60 dB and an input voltage noise density of 150 nV/√Hz. The component is housed in an SOIC-8 surface-mount package and supports operation within a temperature range of 0°C to +70°C.
