**电压参考**：LM399，AD584，AD586，AX6126，REF02
|
||
|
||
**12位DAC**： [MCP4726A](../DAC/串行/MCP4726A.md)
|
||
|
||
**16位DAC**：ADS1259，MAX541，AD569
|
||
|
||
**24位ADC**：ADS1255
|
||
|
||
|
||
|
||
**AD586BR**温漂2ppm/C，年稳15ppm/C，初始精度0.04%

## 拟做可调基准，方案：
|
||
|
||
AD586做总基准电压参考，AD569作DAC输出，ADS1255作ADC回采，STM32F103作控制和显示
|
||
|
||
|
||
|
||
AD586BR输出基准5V，温漂2ppm/C，年稳15ppm/C，初始精度0.04%，可微调
|
||
|
||
AD569，16位DAC，电压输出，自带buffer，高线性、低漂移、低噪声
|
||
|
||
ADS1255，24位ADC
