What the MAX5523EUA+ is and where it fits
The MAX5523EUA+ from Maxim Integrated is a 10-bit, dual-channel digital-to-analog converter with a voltage-buffered output. It uses a current-source architecture and includes an internal reference.
Key ratings and what they mean for the BOM
Two DAC channels in one 8-pin package save board area and per-channel cost compared to using two single DACs. The channels are independent, so each can be updated separately via SPI. 660 µs typical settling time means the output reaches its final value within about two-thirds of a millisecond after a code update. This is adequate for DC set-points, slow ramps, or low-frequency waveform generation, but not for audio or fast control loops. The -40°C to 85°C operating range covers industrial enclosures, outdoor telecom cabinets, and automotive cabin environments without needing a military-grade part.
Package and footprint
Housed in an 8-pin uMAX/uSOP with a 3.00 mm body width, the MAX5523EUA+ fits tight layouts. The surface-mount package is compatible with standard reflow soldering.
Lifecycle and sourcing
The MAX5523EUA+ is listed as Active in production. It is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect.
