The TLV1548 is a CMOS 10-bit switched-capacitor successive-approximaTIon (SAR) analog-to-digital (A/D) converter. The device has a chip select (CS), input-output clock (I/O CLK), data input (DATA IN) and serial data output (DATA OUT) that provides a direct 4-wire synchronous serial peripheral interface (SPI™, QSPI™) port of a host microprocessor. When interfacing with a TMS320 DSP, an addiTIonal frame sync signal (FS) indicates the start of a serial data frame. The device allows high-speed data transfers from the host. The INV CLK input provides further TIming flexibility for the serial interface.
In addiTIon to a high-speed converter and versatile control capability, the device has an on-chip 11-channel multiplexer that can select any one of eight analog inputs or any one of three internal self-test voltages.
