TLV2545 12 位 200 kSPS ADC 系列输出，TMS320 兼容（最高 10MHz）单通道伪差动

The TLV2541, TLV2542, and TLV2545 are a family of high performance, 12-bit, low power, miniature, CMOS analog-to-digital converters (ADC). The TLV254x family operates from a single 2.7-V to 5.5-V supply. Devices are available with single, dual, or single pseudo-differential inputs. Each device has a chip select (CS)\, serial clock (SCLK), and serial data output (SDO) that provides a direct 3-wire interface to the serial port of most popular host microprocessors (SPI interface). When interfaced with a TMS320TM DSP, a frame sync signal (FS) can be used to indicate the start of a serial data frame on CS\ for all devices or FS for the TLV2541.

TLV2541, TLV2542, and TLV2545 are designed to operate with very low power consumption.
