Code for datasheet application - Margining a power supply with the LTC2645 Quad 12-/10-/8-Bit PWM to VOUT DACs with 10ppm/C Reference.
NOTES Setup: Set the terminal baud rate to 115200 and select the newline terminator. Equipment required is a precision voltage source (null box) and a precision voltmeter (to monitor voltage source). No external power supply is required. Ensure JP1 is installed in the default position from the factory. USER INPUT DATA FORMAT: decimal : 1024 hex : 0x400 octal : 02000 (leading 0 "zero") binary : B10000000000 float : 1024.0
