The Maxim Integrated MAX494CSD+ is a quad general-purpose operational amplifier in a 14-SOIC package. It delivers rail-to-rail output swing, a gain bandwidth product of 500 kHz, and a slew rate of 0.2 V/µs. Each of the four channels draws 150 µA supply current, making it suited for multi-channel signal conditioning in battery-powered or low-power instrumentation, sensor interfaces, and portable equipment. The part operates from a single supply spanning 2.7 V to 6 V, or from dual supplies, and is specified over the commercial temperature range of 0°C to 70°C.
500 kHz gain bandwidth — what it means for the signal path
A 500 kHz GBP with 0.2 V/µs slew rate sets the usable bandwidth for closed-loop gains.
Package and footprint
Housed in a 14-SOIC (0.154", 3.90 mm width) surface-mount package, the MAX494CSD+ shares the standard SOIC-14 land pattern. The supplier device package is 14-SOIC, and the part ships in Tube. No special soldering profile beyond standard reflow is required.
The MAX494CSD+ carries an Active lifecycle status and is ROHS3 compliant. There is no end-of-life notice or last-time-buy schedule. For new designs or production replenishment, the part is available through independent distribution and is quoted to order against an RFQ — current pricing and lead time are confirmed at quote time.
