ADS8353IPW集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS8353IPW属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS8353IPW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。

3 Description

The ADS8353, ADS7853, and ADS7253 belong to a family of pin-compatible, dual, high-speed,

simultaneous-sampling, analog-to-digital converters

(ADCs) that support single-ended and pseudo–

differential analog inputs.

Each device includes two individually programmable

reference sources that can be used for system-level gain calibration. Also, a flexible serial interface that

can operate over a wide power-supply range enables

easy communication with a large variety of host

controllers. Power consumption for a given throughput can be optimized by using the two low-

power modes supported by the device. All devices

are fully specified over the extended industrial

temperature range (–40°C to 125°C) and are available in pin-compatible, WQFN-16 (3-mm ×

3-mm) and TSSOP-16 packages.
