16-bit sigma delta analog-to-digital converters (SDADC)
Up to three 16-bit sigma-delta analog-to-digital converters are embedded in the
STM32F37x. They have up to two separate supply voltages allowing the analog function
voltage range to be independent from the STM32F37x power supply. They share up to 21
input pins which may be configured in any combination of single-ended (up to 21) or
differential inputs (up to 11).
The conversion speed is up to 16.6 ksps for each SDADC when converting multiple
channels and up to 50 ksps per SDADC if single channel conversion is used. There are two
conversion modes: single conversion mode or continuous mode, capable of automatically
scanning any number of channels. The data can be automatically stored in a system RAM
buffer, reducing the software overhead.
A timer triggering system can be used in order to control the start of conversion of the three
SDADCs and/or the 12-bit fast ADC. This timing control is very flexible, capable of triggering
simultaneous conversions or inserting a programmable delay between the ADCs.
Up to two external reference pins (VREFSD+, VREFSD-) and an internal 1.2/1.8 V
reference can be used in conjunction with a programmable gain (x0.5 to x32) in order to
fine-tune the input voltage range of the SDADC.
