12-bit dual DAC with 800 ns settling — what that buys the design
The LTC1590CS#TRPBF is a 12-bit dual current-output DAC with R-2R architecture, 800 ns settling time, and SPI interface in a 16-SOIC package.
R-2R architecture and external reference — the precision story
The R-2R ladder gives monotonic performance; ±0.5 LSB max INL and DNL guarantee no missing codes across the 12-bit range. An external reference sets the full-scale output current.
Supply rails and temperature range — fit for the BOM
Both analog and digital supplies are 5 V nominal. The 0°C to 70°C commercial temperature range covers bench, lab, and office equipment.
Package and mounting — board-level reality
Housed in a 16-lead SOIC (3.90 mm body width), the LTC1590CS#TRPBF is a standard surface-mount footprint. No exposed pad, so thermal management is straightforward — just standard SOIC-16 land pattern and 0.65 mm pitch. MSL is not explicitly stated in the record, but for a standard SOIC without exposed pad, MSL 1 or 2 is typical; confirm with the manufacturer if the reel has been opened past the floor-life window.
