Quad CMOS op-amp for battery-powered and automotive signal chains
The AD8619WARZ-R7 from Analog Devices is a quad CMOS rail-to-rail op-amp in a 14-SOIC package. Each of the four amplifiers draws 38 µA supply current while delivering 80 mA output drive and rail-to-rail swing — a combination that suits multi-channel sensor interfaces, battery monitors, and automotive ECU signal conditioning where every microamp counts. The 400 kHz gain-bandwidth product and 0.1 V/µs slew rate set the speed ceiling for low-frequency loops; expect clean settling for signals below a few tens of kilohertz. Input bias current sits at 0.2 pA, so high-impedance sources like photodiodes or pH probes see negligible loading.
Temperature grade and automotive qualification
Rated for -40°C to 125°C, the AD8619WARZ-R7 covers automotive under-hood and industrial environments. The 'W' prefix indicates an automotive-grade variant; the part is fully active per ADI's current lifecycle status and ROHS3 compliant. No end-of-life notice is in effect, so this line is safe for new designs and production ramps.
Sourcing and availability
The AD8619WARZ-R7 is sourced through independent distribution and quoted to order against an RFQ. Availability and pricing are confirmed at quote time.
