NOTE 1: Voltage values for maximum ratings are with respect to VCC.DescriptionThe TLC32040M interface circuit is a complete analog-to-digital and digital-to-analog input/output system on a single monolithic CMOS chip. This TLC32040M integrates a band-pass switched-capacitor antialiasing input filter, a 14-bit-resolution A/D converter, four microprocessor-compatible serial port modes, a 14-bit-resolution D/A converter, and a low-pass switched-capacitor output reconstruction filter.The TLC32040M offers numerous combinations of master clock input frequencies and conversion/sampling rates, which can be changed via digital processor control.
Typical applications for this integrated circuit TLC32040M include modems (7.2-, 8-, 9.6-, 14.4-, and 19.2-kHz sampling rate), analog interface for digital signal processors (DSPs), speech recognition/storage systems, industrial process control, biomedical instrumentation, acoustical signal processing, spectral analysis, data acquisition, and instrumentation recorders. Four serial modes, which allow direct interface to the SMJ320E14, SMJ32020, SMJ320C25, and SMJ320C30 digital signal processors, are provided. Also, when the transmit and receive sections of the analog interface circuit (AIC) are operating synchronously, it will interface to two SN54299 serial-to-parallel shift registers.These serial-to-parallel shift registers of TLC32040M can then interface in parallel to the SMJ320C10, SMJ320C15,SMJ320E15, other digital signal processors, or external FIFO circuitry. Output data pulses are emitted to inform the processor that data transmission is complete or to allow the DSP to differentiate between two transmitted bytes. A flexible control scheme of TLC32040M is provided so that the functions of the integrated circuit can be selected and adjusted coincidentally with signal processing via software control.
