VCC | DAC Output Voltage | Output Current | Error | Maximum Resistive Load |
---|---|---|---|---|
5V | 0mV – 510mV | 0mA – 100mA | <0.25% FSR | 44.9Ω |
The programmable low-side current sink sets the current through a load based on the DAC output voltage. The current is sensed through RSET and the op amp biases a transistor regulate the current through the load. Components CF, RISO, and RFB provide compensation to verify the stability of the circuit.
