Maintaining ratiometric data in electronically manipulated signal processing systems |
摘要 |
A circuit apparatus comprises interface circuitry between analog and digital circuitry. A multiple reference circuit provides a variety of reference voltage signals. The multiple reference circuitry is coupled to a selection circuit that selectively couples one of the reference voltage signals to a first reference input of the interface circuitry and selectively couples another of the reference voltage signals to a second reference input of the interface circuitry, whereby the first and second reference inputs may be selectively coupled to the reference voltages and the circuit maintains a ratiometric relationship between the digital and analog circuitry.
