**Details** This DAC Tibbit is based on the MCP4728 12-bit DAC with I2C interface. All four channels of this DAC are used by the Tibbit. The analog front end of the module allows you to output signals in the -10V to +10V range (respective to the system ground). The MCP4728 DAC IC has a 12-bit resolution. The Tibbit #14 has the effective resolution of around 9~10 bits. This reduction is caused by the system noise and other factors that affect the measurement quality. Combine this Tibbit with #20 (nine terminal blocks) or #19 (DB9M connector). It's not common but possible to use the latter for wiring into the DAC outputs. The Tibbit #21 (four terminal blocks) can also be used but you will have to steal the ground elsewhere, as #21 doesn't have its own ground line and the DAC outputs voltages with respect to the system ground. **LEDs** There are two red, one yellow, and one green LED. The red LEDs are connected to the SCL and LDAC lines, the yellow LED -- to the SDA line, and the green LED -- to the -BUSY line. **Sample project** The use of this Tibbit is illustrated by a Tibbo BASIC test project.
