TLC2551IDR集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

TLC2551IDR属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的TLC2551IDR模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。

description

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. This product family features a high-speed

serial link to modern host processors with SCLK up to 20 MHz. The maximum SCLK frequency is dependent

upon the mode of operation (see Table 1). The TLC255x family uses SCLK as the conversion clock, which

provides synchronous operation and a minimum conversion time of 1.5 μs using a 20-MHz SCLK.
