3.16
Operational amplifier (OPAMP)
The STM32F303xD/E embed four operational amplifiers with external or internal follower
routing and PGA capability (or even amplifier and filter capability with external components).
When an operational amplifier is selected, an external ADC channel is used to enable
output measurement.
The operational amplifier features:
•
8.2 MHz bandwidth
•
0.5 mA output capability
•
Rail-to-rail input/output
•
In PGA mode, the gain is programmed to be 2, 4, 8 or 16.
3.17
Ultra-fast comparators (COMP)
The STM32F303xD/E devices embed seven ultra-fast rail-to-rail comparators with
programmable reference voltage (internal or external) and selectable output polarity.
The reference voltage can be one of the following:
•
External I/O
•
DAC output pin
•
Internal reference voltage or submultiple (1/4, 1/2, 3/4). Refer to Table 23: Embedded
internal reference voltage for the value and precision of the internal reference voltage.
All comparators can wake up from STOP mode, generate interrupts and breaks for the
timers.
3.18
Timers and watchdogs
The STM32F303xD/E include three advanced control timers, up to six general-purpose
timers, two basic timers, two watchdog timers and one SysTick timer. The table below
compares the features of the advanced control, general purpose and basic timers.
