14Bit 100KSPS 模数转换器

本芯片是一款14位、逐次逼近型模数转换器(ADC)，采用单电源供电，电源电压同时用作ADC的基准信号，极大地简化了芯片的外围电路。它内置一个低功耗、高精度的14位采样ADC和一个串行接口端口。在CS上下降沿，该器件对VIN端口的模拟输入电压进行采样，范围从0至VDD。本芯片与国外产品AD7940管脚兼容，可实现替代。芯片的功能结构框图如下图所示： • 转换位数：14Bit\n• 吞吐速率：100KSPS\n• 低功耗：4~17mW\n• INL：±0.5LSB（典型值）\n• SNDR：81dB@10kHz输入\n• THD：-98dB@10kHz输入\n• 伪差分输入范围： 0至VDD（VDD=2.5~5.5）\n• 无流水线延迟\n• 串行接口：SPI兼容\n• 封装：SOT23;
