TLC2555 12 位 400kSPS ADC，具有串行输出、TMS320 兼容（最高 10MHz）和单通道伪差动

The TLC2551, TLC2552, and TLC2555 are a family of high performance, 12-bit, low-power, miniature, CMOS analog-to-digital converters (ADC). The TLC255x family uses a 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 TMS320™ DSP, a frame sync signal (FS) can be used to indicate the start of a serial data frame on CS\ for all devices or on FS for the TLC2551.

The TLC2551, TLC2552, and TLC2555 are designed to operate with very low power consumption. The power saving feature is further enhanced with an autopower down mode.
