Design of Precise DC Millivolt Signal Source Based on System-on-Chip of C8051F410
This paper describes design process of thermocouple signal precise source. System-on-chip of C8051F410 is a key to signal source. It can realize 15 bit analog output through internal two-path 12 bit current output type D/A .Signal amplification circuit includes power supply circuit, low drift, low noise signal that can be verification source of thermocouple measuring instrument.
