Rated for -40°C to 125°C, the MAX44246ASA+ fits industrial control cabinets, outdoor telecom enclosures, and automotive under-hood electronics. The 8-SOIC footprint is a standard layout for dual op-amps.
ROHS3 compliant.
Within the same dual general-purpose op-amp class, parts like the OPA2192 or ADA4522-2 offer similar rail-to-rail output and low offset but differ in GBW and supply current. The MAX44246ASA+ sits at 5 MHz with 420 µA per channel — a balance of speed and power that a higher-GBW part like the OPA2192 (10 MHz, 1.1 mA) does not match. Pin compatibility depends on the exact compensation and shutdown pin assignments; verify the footprint against your layout before substituting.
The slew rate is 3.8 V/µs, which supports signal swings up to roughly 600 kHz at full output without slew-induced distortion — adequate for audio and low-frequency control loops.
It ships in an 8-SOIC package (0.154", 3.90 mm width) on Tube. The supplier device package is also 8-SOIC. Surface-mount only.
