MCP3021集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

MCP3021属于集成电路（IC）的模数转换器（ADC）。由微芯科技股份有限公司制造生产的MCP3021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。

描述 Description

The Microchip Technology Inc. MCP3021 is a successive approximation A/D converter (ADC) with 10-bit resolution. Available in the SOT-23 package, this device provides one single-ended input with very low power consumption. Based on an advanced CMOS technology, the MCP3021 provides a low maximum conversion current and standby current of 250 µA and 1 µA, respectively. Low current consumption, combined with the small SOT-23 package, make this device ideal for battery-powered and remote data acquisition applications.
