MCP3021数据手册集成电路（IC）的模数转换器（ADC）规格书PDF

描述 Description

The MCP3021 is a successive approximation A/D converter with 10-bit resolution. Available in the SOT-23 package, this device provides one, single-ended input with very low power consumption. 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. Communication to the MCP3021 is performed using a 2-wire I2C™Compatible compatible interface. Standard (100 kHz) and Fast (400 kHz) I2C™Compatible modes are available with the device. An on-chip conversion clock enables independent timing for the I2C™Compatible clock and the conversion clock. The device is also addressable allowing up to eight devices on a single 2-wire bus. The MCP3021 runs on a single supply voltage that operates over a broad range of 2.7 V to 5.5 V. This device also provides excellent linearity of ±1 LSB differential non-linearity and ±1 LSB integral non-linearity. Operating temperature range for this device is -40°C to +125°C.

简介

MCP3021属于集成电路（IC）的模数转换器（ADC）。由制造生产的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。
