165 / 220 page  DS11189 Rev 7 165/220 STM32F469xx Electrical characteristics 191 Figure 58. 12-bit buffered/non-buffered DAC 1. The DAC integrates an output buffer that can be used to reduce the output impedance and to drive external loads directly without the use of an external operational amplifier. The buffer can be bypassed by configuring the BOFFx bit in the DAC_CR register. 5.3.29 FMC characteristics Unless otherwise specified, the parameters given in Tables 88 through 101 for the FMC interface are derived from tests performed under the ambient temperature, fHCLK frequency and VDD supply voltage conditions summarized in Table 17, with the following configuration: Output speed is set to OSPEEDRy[1:0] = 11 Measurement points are done at CMOS levels: 0.5 VDD Refer to Section 5.3.20 for more details on the input/output characteristics. Asynchronous waveforms and timings Figures 59 through 62 represent asynchronous waveforms, and Tables 88 through 95 provide the corresponding timings. The results shown in these tables are obtained with the following FMC configuration: AddressSetupTime = 0x1 AddressHoldTime = 0x1 DataSetupTime = 0x1 (except for asynchronous NWAIT mode , DataSetupTime = 0x5) BusTurnAroundDuration = 0x0 Capacitive load CL = 30 pF R L C L Buffered/Non-buffered DAC DAC_OUTx Buffer(1) 12-bit digital to analog converter ai17157V2 |
