TLV2544 概述

The TLV2544 are high performance, 12-bit low power, 3.86 µs, CMOS analog-to-digital converters (ADC) which operate from a single 2.7-V to 5.5-V power supply. The TLV2544 have three digital inputs and a 3-state output [chip select (CS)\, serial input-output clock (SCLK), serial data input (SDI), and serial data output (SDO)] that provide a direct 4-wire interface to the serial port of most popular host microprocessors (SPI interface). When interfaced with a TI DSP, a frame sync (FS) signal is used to indicate the start of a serial data frame.

The TLV2544C are characterized for operation from 0°C to 70°C. The TLV2544I are characterized for operation from –40°C to 85°C.
