mbed_official | 237:f3da66175598 | 23 | ##### OPAMP Peripheral Features ##### |
mbed_official | 237:f3da66175598 | 24 | ================================================================================ |
mbed_official | 237:f3da66175598 | 25 | |
mbed_official | 237:f3da66175598 | 26 | [..] The device integrates up to 4 operational amplifiers OPAMP1, OPAMP2, |
mbed_official | 237:f3da66175598 | 27 | OPAMP3 and OPAMP4: |
mbed_official | 237:f3da66175598 | 28 | |
mbed_official | 237:f3da66175598 | 29 | (#) The OPAMP(s) provides several exclusive running modes. |
mbed_official | 237:f3da66175598 | 30 | (+) Standalone mode |
mbed_official | 237:f3da66175598 | 31 | (+) Programmable Gain Amplifier (PGA) mode (Resistor feedback output) |
mbed_official | 237:f3da66175598 | 32 | (+) Follower mode |
mbed_official | 237:f3da66175598 | 33 | |
mbed_official | 237:f3da66175598 | 34 | (#) The OPAMP(s) provide(s) calibration capabilities. |
mbed_official | 237:f3da66175598 | 35 | (+) Calibration aims at correcting some offset for running mode. |
mbed_official | 237:f3da66175598 | 36 | (+) The OPAMP uses either factory calibration settings OR user defined |
mbed_official | 237:f3da66175598 | 37 | calibration (trimming) settings (i.e. trimming mode). |
mbed_official | 237:f3da66175598 | 38 | (+) The user defined settings can be figured out using self calibration |
mbed_official | 375:3d36234a1087 | 39 | handled by HAL_OPAMP_SelfCalibrate, HAL_OPAMPEx_SelfCalibrateAll |
mbed_official | 237:f3da66175598 | 40 | (+) HAL_OPAMP_SelfCalibrate: |
mbed_official | 237:f3da66175598 | 41 | (++) Runs automatically the calibration in 2 steps. |
mbed_official | 237:f3da66175598 | 42 | (90% of VDDA for NMOS transistors, 10% of VDDA for PMOS transistors). |
mbed_official | 237:f3da66175598 | 43 | (As OPAMP is Rail-to-rail input/output, these 2 steps calibration is |
mbed_official | 237:f3da66175598 | 44 | appropriate and enough in most cases). |
mbed_official | 237:f3da66175598 | 45 | (++) Enables the user trimming mode |
mbed_official | 237:f3da66175598 | 46 | (++) Updates the init structure with trimming values with fresh calibration |
mbed_official | 237:f3da66175598 | 47 | results. |
mbed_official | 237:f3da66175598 | 48 | The user may store the calibration results for larger |
mbed_official | 237:f3da66175598 | 49 | (ex monitoring the trimming as a function of temperature |
mbed_official | 237:f3da66175598 | 50 | for instance) |
mbed_official | 237:f3da66175598 | 51 | (++) for STM32F3 devices having 2 or 4 OPAMPs |
mbed_official | 375:3d36234a1087 | 52 | HAL_OPAMPEx_SelfCalibrateAll |
mbed_official | 237:f3da66175598 | 53 | runs calibration of 2 or 4 OPAMPs in parallel. |
mbed_official | 237:f3da66175598 | 54 | |
mbed_official | 237:f3da66175598 | 55 | (#) For any running mode, an additional Timer-controlled Mux (multiplexer) |
mbed_official | 237:f3da66175598 | 56 | mode can be set on top. |
mbed_official | 237:f3da66175598 | 57 | (+) Timer-controlled Mux mode allows Automatic switching between inverting |
mbed_official | 237:f3da66175598 | 58 | and non-inverting input. |
mbed_official | 237:f3da66175598 | 59 | (+) Hence on top of defaults (primary) inverting and non-inverting inputs, |
mbed_official | 237:f3da66175598 | 60 | the user shall select secondary inverting and non inverting inputs. |
mbed_official | 237:f3da66175598 | 61 | (+) TIM1 CC6 provides the alternate switching tempo between defaults |
mbed_official | 237:f3da66175598 | 62 | (primary) and secondary inputs. |
mbed_official | 237:f3da66175598 | 63 | |
mbed_official | 237:f3da66175598 | 64 | (#) Running mode: Standalone mode |
mbed_official | 237:f3da66175598 | 65 | (+) Gain is set externally (gain depends on external loads). |
mbed_official | 237:f3da66175598 | 66 | (+) Follower mode also possible externally by connecting the inverting input to |
mbed_official | 237:f3da66175598 | 67 | the output. |
mbed_official | 237:f3da66175598 | 68 | |
mbed_official | 237:f3da66175598 | 69 | (#) Running mode: Follower mode |
mbed_official | 237:f3da66175598 | 70 | (+) No Inverting Input is connected. |
mbed_official | 237:f3da66175598 | 71 | |
mbed_official | 237:f3da66175598 | 72 | (#) Running mode: Programmable Gain Amplifier (PGA) mode |
mbed_official | 237:f3da66175598 | 73 | (Resistor feedback output) |
mbed_official | 237:f3da66175598 | 74 | (+) The OPAMP(s) output(s) can be internally connected to resistor feedback |
mbed_official | 237:f3da66175598 | 75 | output. |
mbed_official | 237:f3da66175598 | 76 | (+) OPAMP gain is either 2, 4, 8 or 16. |
mbed_official | 237:f3da66175598 | 77 | |
mbed_official | 237:f3da66175598 | 78 | (#) The OPAMPs non inverting input (both default and secondary) can be |
