Closed loop dac glitch mitigation

An amplifier system including:

• at least one digital to analog converter (DAC) circuit, wherein setting a DAC code in the at least one DAC circuit sets an output of the at least one DAC circuit;
• multiple amplifier circuits including inputs connected to the output of the at least one DAC circuit;
• a feedback circuit path connected to a system output of the amplifier system;
• and
• a control circuit connected to the at least one DAC circuit and the feedback circuit path, wherein the control circuit is configured to:
• operate the at least one DAC circuit using a first set of DAC codes to set the system output to a steady state output target;
• and
• change to operating the at least one DAC circuit using a second set of DAC codes to maintain the same steady state output target and to reduce ripple at the system output caused by the at least one DAC circuit.

A power supply system having closed loop control, the power supply system comprising:

• multiple digital to analog converter (DAC) channels, each DAC channel including a DAC circuit connected to an input of an amplifier circuit;
• a summing node connected to outputs of the amplifier circuits of the DAC channels to provide a system output;
• and
• a control circuit operatively coupled to the DAC channels and the system output, wherein the control circuit is configured to:
• update the DAC circuits of the DAC channels with DAC codes to adjust the system output to a steady state target output in a steady state, wherein the DAC codes are selected from a first set of DAC codes;
• detect when the DAC codes selected from the first set of DAC codes result in a glitch condition at outputs of the DAC circuits in the steady state;
• and
• change to selecting the DAC codes from a second set of DAC codes that maintain the same steady state target output and reduce glitching at the outputs of the DAC circuits.
