ADS5240中文资料四通道、12 位、40MSPS 模数转换器 (ADC)数据手册TI规格书

描述 Description

The ADS5240 is a high-performance, 40MSPS, 4-channel analog-to-digital converter (ADC). Internal references are provided, simplifying system design requirements. Low power consumption allows for the highest of system integration densities. Serial LVDS (low-voltage differential signaling) outputs reduce the number of interface lines and package size.An integrated phase lock loop (PLL) multiplies theincoming ADC sampling clock by a factor of 12. This high-frequency LVDS clock is used in the data serialization and transmission process. The word output of each internal ADC is serialized and transmitted either MSB or LSB first. In addition to the four data outputs, a bit clock and a word clock are also transmitted. The bit clock is at 6x the speed of the sampling clock, whereas the word clock is at the same speed of the sampling clock.The ADS5240 provides internal references, or can optionally be driven with external references. Best performance can be achieved through the internal reference mode.The device is available in an HTQFP-64 PowerPAD package and is specified over a -40°C to +85°C operating range.

简介

ADS5240属于集成电路（IC）的模数转换器（ADC）。由TI制造生产的ADS5240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。
