DESCRIPTION

Demonstration circuit 2692A-A features the

5-channel, 16-bit, 300mA, current source DACs with

10ppm/°C reference in a 5mm × 5mm QFN package.

This device features per-channel SoftSpan™ configura-

tion of 3.125mA to 300mA, a separate supply for each

output, and an internal switch to allow any output pin to

–

be connected to V
