Differential Mode SDADC Codes

Posted on May 26, 2016 at 04:57I need to know what the differential mode SDADC conversion code is. Is it 2's compliment such that the code:  int16_t D = (int16_t)HAL_SDADC_GetValue(&hsdadc3); Will return to D a signed result such that if the positiv...

STM32F373 sdadc linearity at low input drops off

Posted on March 20, 2016 at 18:07With a 'F373 I find that the sdadc counts-per-volt of the SDADC drops off rather dramatically when the input voltage decreases below about 40% of FS.  I would like to understand the mechanism behind this before locki...

Configuring SDADC and ADC Repeat Triggering With DMA

Posted on January 16, 2016 at 07:06I am triggering ADC1 from TIM4->CCR4 and SDADC1 from TIM4->CCR1. ADC1 is configured for regular conversions and no injected conversions. SDADC1 is configured for injected conversions and no regular conversions. For...

SDADC Gain 0.5 max Vin?

Posted on December 08, 2015 at 22:02Hi, According to AN4207 page 10, in Single ended zero ref mode the max input voltage to the ADC is Vref/gain. So if I set Vref = 3.3V = VCC, can I measure up to 6.6V with gain = 0.5? Or would this collide with the...


STM32F373 SDADC (Sigma-Delta ADC)

Posted on March 18, 2014 at 03:12Hello, I am planning on using the SDADC in STM32F37x microcontroller.  The data sheets says the sampling frequency is between 500 kHz ~ 6 MHz, depending on the clock signal driving the SDADC.  The output data rate is...

SDADC2 synchronization with SDADC1

Posted on November 26, 2014 at 10:43I have seen a lost of discussions about synchronized sampling of ADCs. But I haven't seen a single example for synchronized sampling of SDADCs anywhere. I am using stm32f373 MCU where I want to sample SDADC1 and S...
