1 Introduction
The TLC320AD58C provides high-resolution signal conversion from analog to digital using oversampling
sigma-delta technology. This device consists of two synchronous conversion paths. Also included is a
decimation filter after the modulator as shown in the functional block diagram. Other functions provide
analog filtering and on-chip timing and control.
A functional block diagram of the TLC320AD58C is included in Section 1.2. Each block is described in the
detailed description section.
