Product Summary
The TLV1548IDBR is a CMOS 10-bit switched-capacitor successive-approximation (SAR) analog-to-digital (A/D) converter. Each TLV1548IDBR 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 (SPIE, QSPIE) port of a host microprocessor. The TLV1548IDBR is designed to operate with a wide range of supply voltages with very low power consumption. The power saving feature is further enhanced with a software-programmed power-down mode and conversion rate.
