Working Principle

The LTC2637IMS-LMX10#TRPBF is based on a 10-bit R2R architecture. This technology uses a series of resistors connected in a ladder to generate the desired output voltage. A resistor ladder is made up of several discrete resistors, connected in a ladder configuration. Each individual resistor in the ladder is given a numerical value. When the desired output voltage reference is applied to the ladder, the corresponding resistor values will be summed to generate the ~ output voltage.

Each tap on the ladder has its own R2R bit and the voltage output at each tap is proportional to the sum of each resistor in the ladder. The output of each tap is further converted to digital value by a 10-bit DAC converter, which is the basic working principle of the LTC2637IMS-LMX10#TRPBF.

The DAC can be calibrated using the internal reference voltage, either via an external digital control signal, or by using the onboard 8-bit EEPROM. The DAC also includes a programmable digital output code feature which can be used to monitor the output level of the DAC, as well as a 3-state output port which can be used to drive external circuits or logic.
