ADS7056 是 TI 推出的一款 高速、低功耗、超小尺寸的 14 位 SAR ADC（逐次逼近型 ADC），适合电池供电、体积敏感的高速采样场景。 输入端等效为 Rs（约 50 Ω）+ Cs（16 pF）；外部建议加 RC 滤波器（C > 320 pF）避免 charge kickback。 比较器 + DAC：执行逐次逼近。 数字控制 ...

电容模数转换器与电荷注入模数转换器融合的SAR ADC结构优化，采用紧凑电荷注入单元和脉冲门控数字控制，在28nm CMOS工艺下实现0.000259 mm2面积和0.835 mW功耗，支持700 MHz采样频率，达到38.7 dB SNDR和17.03 fJ/conv-step能效，显著优于传统时间 interleaving ADC设计。 摘要 ...

Dewesoft released an innovation in the data acquisition world. For years engineers have faced a difficult choice between delta-sigma and SAR (successive approximation) ADCs (analog to digital ...

Low cost microcontrollers are increasingly expected to provide high performance analog functions for applications that previously used stand-alone ADCs. These applications include power metering, ...
