11.5.7 Current Digital-to-analog Converter (IDAC)
All specifications are based on use of the low-resistance IDAC output pins (see Pin Descriptions on page 9 for details). See the IDAC
component data sheet in PSoC Creator for full electrical specifications and APIs.
Unless otherwise specified, all charts and graphs show typical values.
