ABSTRACT:
A method and apparatus for testing an analog to digital converter (14) having a capacitor digital to analog converter (30). In one form, the analog to digital converter uses a small amount of capacitor test logic (44) to test for opens and shorts in the capacitor array (42), the switch logic (38), and the decode logic (36). Instead of performing time-consuming analog to digital conversions, the functionality of the above mentioned circuitry is tested by using AND and OR logical functions. As a result of using capacitor test logic (44), a very quick pass/fail functional test can be performed on the analog to digital converter (14) without requiring the analog to digital converter (14) to perform time-consuming analog to digital conversions.
