Description
Demonstration circuit 1332B features the
2
12-bit I
C DAC with 1LSB (max) INL error. This device
establishes a new benchmark for size and integration of
12-bit DACs and onboard reference.
The DC1332B may be connected directly to the target
application's analog signals while using the DC590 USB
serial controller board and supplied software to measure
