TLV1544 说明

The TLV1544 and TLV1548 are CMOS 10-bit switched-capacitor successive-approximation (SAR) analog-to-digital (A/D) converters. Each device has a chip select (CS\), input-output clock (I/O CLK), data input (DATA IN) and serial data output (DATA OUT) that provide a direct 4-wire synchronous serial peripheral interface (SPITM, QSPITM) 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 devices allow 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.
