14-bit、1.5Msps、低功率的SAR模数转换器LTC2351-14具有六路同时采样的差分输入通道。工作于3V电源，具有6个独立的采样保持放大器和单个ADC；LTC2351-14是工业监控应用的理想选择，如3相线电压监控，手持设备电源、功率因数校正、电机控制、数据采集等应用。6-Channel SAR ADCs for Industrial Monitoring and Portable Instruments Design Note 426 Guy Hoover and Steve Logan The 14-bit LTC2351-14 is a 1.5Msps, low power SAR low power and small size are desirable. Power consump- ADC with six simultaneously sampled differential input tion is a mere 16.5mW, which extends battery life. The channels. It operates from a single 3V supply and features 3-wire serial interface means fewer pins than parallel six independent sample-and-hold ampliers and a single output devices, allowing the LTC2351-14 to t in a 32-pin, ADC. The single ADC with multiple S/HAs enables excellent 5mm × 5mm QFN package. range match (1mV) between channels and channe……
