It operates from a single 5V supply for both analog and digital rails, simplifying the power tree — no separate analog rail needed. The multiplying DAC architecture means the output is the product of the digital code and an external reference voltage, giving the designer direct control over the full-scale range through the reference pin. Rated for -55°C to 125°C operating temperature, this part covers the full military-grade envelope — suitable for avionics, downhole instrumentation, and engine-bay control modules where the ambient swings beyond industrial limits. The 20-SOIC wide-body package (7.50mm width) provides better thermal dissipation than the narrow SOIC variant and matches a standard surface-mount footprint for automated assembly. Note the RoHS non-compliant flag — this part uses lead-bearing solder termination, which matters for EU RoHS-exempt applications (military, aerospace, medical implant) but will not pass a standard RoHS-10 screening.","metaTitle":"PM7645BR 12-bit Multiplying DAC, 1µs, ±0.5 LSB INL, 20-SOIC","metaDescription":"PM7645BR 12-bit buffered multiplying DAC, 1µs settling, ±0.5 LSB INL, -55°C to 125°C range.
