    摘要: A supply voltage detect circuit is described which generates a control signal indicating the status of VCC to be at 5.0 or 3.3 volts. This control signal is used to generate analog reference signals used by A/D and/or D/A circuitry in an audio processing integrated circuit and by other circuitry to control clock frequencies or current drive.
