ADS5237中文资料双通道、10 位、65MSPS 模数转换器 (ADC)数据手册TI规格书

描述 Description

The ADS5237 is a dual, high-speed, high dynamic range, 10-bit, pipelined analog-to-digital converter (ADC). This device includes a high-bandwidth sample-and-hold amplifier that gives excellent spurious performance up to and beyond the Nyquist rate. The differential nature of the sample-and-hold amplifier and ADC circuitry minimizes even-order harmonics and gives excellent common-mode noise immunity.The ADS5237 provides for setting the full-scale range of the converter without any external reference circuitry. The internal reference can be disabled, allowing low-drive, external references to be used for improved tracking in multichannel systems. The ADS5237 provides an over-range indicator flag to indicate an input signal that exceeds the full-scale input range of the converter. This flag can be used to reduce the gain of front-end gain control circuitry. There is also an output enable pin to allow for multiplexing and testing on a printed circuit board (PCB). The ADS5237 employs digital error correction techniques to provide excellent differential linearity for demanding imaging applications. The ADS5237 is available in a TQFP-64 package.

简介

ADS5237属于集成电路（IC）的模数转换器（ADC）。由TI制造生产的ADS5237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。
