Evaluates: DS4422/DS4424 DS4424 Evaluation Kit General Description Features 2 The DS4422 and DS4424 contain two or four I C- Easy Evaluation of the DS4424 programmable current DACs that are each capable of EV Kit Hardware is USB Powered sinking and sourcing current up to 200A. USB HID Interface The DS4424 evaluation kit (EV kit) provides the hardware Windows XP- and Windows 7-Compatible and software graphical user interface (GUI) necessary to Software evaluate the DS4424 4-channel, 7-bit sink/source current RoHS Compliant DAC. The DS4422 has the same performance as the DS4424, except with only two channels. Proven PCB Layout The EV kit includes a DS4424 installed, as well as two pop- Fully Assembled and Tested ulated full-scale calibration resistors (R3 and R4) and two unpopulated resistors (R5 and R6). This allows the device EV Kit Contents to be evaluated without any board rework on two channels Assembled Circuit Board Including DS4424 but enables a custom-defined value to be populated on the 2 two open channels. The EV kit also has the USB-to-I C Ordering Information appears at end of data sheet. interface required to communicate to the device.
