Abstract
In a data acquisition system, digitizing circuitry (A) is powered up by a control signal (ADC_CONVST), superimposing a glitch (-) on a first multiplexed and amplified signal value (V) received by the digitizing circuitry. Sampling and holding of the first multiplexed and amplified signal value occurs during a delay provided between the glitch and a beginning of a first A/D conversion of the first multiplexed and amplified signal value to allow settling of the glitch. After the first conversion begins, a second multiplexed and amplified signal value is generated. The digitizing circuitry performs the first A/D conversion during initial settling of the second multiplexed and amplified signal value and then is powered down while the second multiplexed and amplified signal value continues to settle.
