70 / 84 page  Electrical characteristics STM32F100x4, STM32F100x6, STM32F100x8, STM32F100xB 70/84 Doc ID 16455 Rev 2 5.3.17 DAC electrical specifications Table 45. DAC characteristics Symbol Parameter Min Typ Max(1) Unit Comments VDDA Analog supply voltage 2.4 3.6 V VREF+ Reference supply voltage 2.4 3.6 V VREF+ must always be below VDDA VSSA Ground 0 0 V RLOAD (2) Resistive load with buffer ON 5 k RO (1) Impedance output with buffer OFF 15 k When the buffer is OFF, the Minimum resistive load between DAC_OUT and VSS to have a 1% accuracy is 1.5 M CLOAD (1) Capacitive load 50 pF Maximum capacitive load at DAC_OUT pin (when the buffer is ON). DAC_OUT min(1) Lower DAC_OUT voltage with buffer ON 0.2 V It gives the maximum output excursion of the DAC. It corresponds to 12-bit input code (0x0E0) to (0xF1C) at VREF+ = 3.6 V and (0x155) and (0xEAB) at VREF+ = 2.4 V DAC_OUT max(1) Higher DAC_OUT voltage with buffer ON VDDA – 0.2 V DAC_OUT min(1) Lower DAC_OUT voltage with buffer OFF 0.5 mV It gives the maximum output excursion of the DAC. DAC_OUT max(1) Higher DAC_OUT voltage with buffer OFF VREF+ – 1LSB V IDDVREF+ DAC DC current consumption in quiescent mode (Standby mode) 220 µA With no load, worst code (0xF1C) at VREF+ = 3.6 V in terms of DC consumption on the inputs IDDA DAC DC current consumption in quiescent mode (Standby mode) 380 µA With no load, middle code (0x800) on the inputs 480 µA With no load, worst code (0xF1C) at VREF+ = 3.6 V in terms of DC consumption on the inputs DNL(3) Differential non linearity Difference between two consecutive code-1LSB) ±0.5 LSB Given for the DAC in 10-bit configuration ±2 LSB Given for the DAC in 12-bit configuration INL(3) Integral non linearity (difference between measured value at Code i and the value at Code i on a line drawn between Code 0 and last Code 1023) ±1 LSB Given for the DAC in 10-bit configuration ±4 LSB Given for the DAC in 12-bit configuration |
