1 Introduction
The TLC320AD56C provides high resolution low-speed signal conversion from digital-to-analog (D/A) and
from analog-to-digital (A/D) using oversampling sigma-delta technology. This device consists of two serial
synchronous conversion paths (one for each data direction) and includes an interpolation filter before the
digital-to-analog converter (DAC) and a decimation filter after the analog-digital-converter (ADC) (see
Figure 1–1). Other overhead functions provide on-chip timing and control. The sigma-delta architecture
produces high resolution A/D and D/A conversion at low system speeds and low cost.
The options and the circuit configurations of this device can be programmed through the serial interface.
The options include reset, power-down, communications protocol, serial clock rate, and test mode as
outlined in Appendix A. The TLC320AD56C is characterized for operation from 0
°
C to 70
°
C.
