Method of forming an audio amplifier voltage reference and structure therefor |
摘要 |
An audio amplifier system (10) is formed to include a voltage reference (16). The voltage reference (16) is formed to utilize a filter having a first cut-off frequency when the output (14) of the voltage reference (16) is less than a first value and to use a second cut-off frequency when the output (14) is greater than the first value.
