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.","metaTitle":"LTC1590CS#TRPBF 12-bit dual DAC, 800 ns settling, SPI","metaDescription":"LTC1590CS#TRPBF 12-bit dual current-output DAC with 800 ns settling, ±0.5 LSB INL/DNL, SPI interface, external reference.
