TLC3578IDWR

Product Summary

The TLC3578IDWR is a high-performance, low-power, CMOS analog-to-digital converter (ADC). The TLC3578IDWR is a 14-bit ADC. All parts operate from single 5-V analog power supply and 3-V to 5-V digital supply. The serial interface consists of four digital input [chip select (CS), frame sync (FS), serial input-output clock (SCLK), serial data input (SDI)], and a 3-state serial data output (SDO). CS (works as SS, slave select), SDI, SDO and SCLK form an SPI interface. FS, SDI, SDO, and SCLK form DSP interface. The frame sync signal (FS) indicates the start of a serial data frame being transferred. When multiple converters connect to one serial port of a DSP, CS works as the chip select to allow the host DSP to access the individual converter. CS can be tied to ground if only one converter is used. FS must be tied to DVDD if it is not used (such as in an SPI interface). When SDI is tied to DVDD, the TLC3578IPWR is set in hardware default mode after power on and no software configuration is required. In the simplest case, only three wires (SDO, SCLK, and CS or FS) are needed to interface with the host.
