Zusammenfassung:An integrated circuit (IC), comprising: a first input pin for receiving a first input signal; a first converter configured to convert the first input signal to a first output signal; a first gain stage configured to apply a first gain to the first output signal; gain update circuitry configured to: output a first external gain control signal to a first output pin of the IC; and subsequently output a first internal gain control signal to the first gain stage to update the first gain of the first gain stage, wherein output of the first internal gain control signal is delayed relative to output of the first external gain control signal by a first predetermined delay, the first predetermined delay to compensate for signal chain delay between the first input pin and the first gain stage.
