ADC120数据手册集成电路（IC）的模数转换器（ADC）规格书PDF

描述 Description

The ADC120 is a low-power, eight-channel pure CMOS 12-bit analog-to-digital converter specified for conversion from 50 ksps to 1 Msps, tested at 1 Msps. The architecture is based on a successive-approximation register with an internal track-and-hold cell. The ADC120 features 8 single ended multiplexed inputs. The output serial data is straight binary and is SPI™ compatible.
The analog and digital power supplies operate from 2.7 V to 3.6 V. The power consumption at 3.3 V nominal supply is as low as 6.6 mW. The ADC120 comes plastic TSSOP-16, and can operates from -40 °C to +125 °C ambient temperature.

简介

ADC120属于集成电路（IC）的模数转换器（ADC）。由制造生产的ADC120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。
