TLV2548-EP 增强型产品 2 位 200kSPS ADC，具有串行输出、自动断电（软件和硬件）、低功耗、8 x FIFO 和 8 通道

The TLV2548 is a high performance, 12-bit low-power, 3.86-µs, CMOS analog-to-digital converter (ADC) which operates from a single 3.0-V to 5.5-V power supply. This device has 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.

In addition to a high-speed A/D converter and versatile control capability, this device has an on-chip analog multiplexer that can select any analog inputs or one of three internal self-test voltages.
