The comparator (COMP) compares an input voltage (VIN+) against a second input voltage (VIN-). VIN+ can be derived from an analog input pin (AIN0-AIN7). VIN- can be derived from multiple sources depending on the operation mode of the comparator.
The main features of COMP are the following:
Once enabled (using the ENABLE register), the comparator is started by triggering the START task and stopped by triggering the STOP task. The comparator will generate a READY event to indicate when it is ready for use and the output is correct. The delay between START and READY is tINT_REF,START if an internal reference is selected, or t COMP,START if an external reference is used. When the COMP module is started, events will be generated every time VIN+ crosses VIN-.
The comparator can be configured to operate in two main operation modes: differential mode and single-ended mode. See the MODE register for more information. In both operation modes, the comparator can operate in different speed and power consumption modes (low-power, normal and high-speed). High-speed mode will consume more power compared to low-power mode, and low-power mode will result in slower response time compared to high-speed mode.
Use the PSEL register to select any of the AIN0-AIN7 pins as VIN+ input, regardless of the operation mode selected for the comparator. The source of VIN- depends on which of the following operation mode are used:
The selected analog pins will be acquired by the comparator once it is enabled.
An optional hysteresis on VIN+ and VIN- can be enabled when the module is used in differential mode through the HYST register. In single-ended mode, VUP and VDOWN thresholds can be set to implement a hysteresis using the reference ladder (see Comparator in single-ended mode ). This hysteresis is in the order of magnitude of VDIFFHYST, and shall prevent noise on the signal to create unwanted events. See Hysteresis example where VIN+ starts below VUP for an illustration of the effect of an active hysteresis on a noisy input signal.
An upward crossing will generate an UP event and a downward crossing will generate a DOWN event. The CROSS event will be generated every time there is a crossing, independent of direction.
The immediate value of the comparator can be sampled to RESULT register by triggering the SAMPLE task.
An optional configurable current can be applied on the AINx pad currently selected for VIN+, as illustrated in the following figure. The AINx pad is configured in register PSEL and the current source in register ISOURCE.
Enabling ISOURCE creates a feedback path around the comparator, forming a relaxation oscillator. The circuit will sink current from VIN+ when the comparator output is high, and source current into VIN+ when the comparator output is low. The frequency of the oscillator is dependent on the capacitance at the analog input pin, the reference voltages, and the value of the current source. When using ISOURCE, a capacitive sensor can to be attached between the analog input pin and ground. With a selected current of 10 μA, VUP-VDOWN equal to 1 V, and an external capacity of typically 10 pF, the resulting oscillation frequency is around 500 kHz.
f_OSC = I_SOURCE / (2C∙(VUP-VDOWN) )
The COMP shares analog resources with other analog peripherals.
While it is possible to use the SAADC at the same time as the COMP, selecting the same analog input pin for both peripherals is not supported.
Additionally, COMP shares registers and other resources with other peripherals that have the same ID as the COMP. See Peripherals with shared ID for more information.
The COMP peripheral shall not be disabled (by writing to the ENABLE register) before the peripheral has been stopped. Failing to do so may result in unpredictable behavior.
In differential mode, the reference input VIN- is derived directly from one of the AINx pins.
Before enabling the comparator via the ENABLE register, the following registers must be configured for the differential mode:
When the HYST register is turned on during this mode, the output of the comparator and associated events do the following:
This behavior is illustrated in the following figure.
In single-ended mode, VIN- is derived from the reference ladder.
Before enabling the comparator via the ENABLE register, the following registers must be configured for the single-ended mode:
The reference ladder uses the reference voltage (VREF) to derive two new voltage references, VUP and VDOWN. VUP and VDOWN are configured using THUP and THDOWN respectively in the TH register. VREF can be derived from any of the available reference sources, configured using the EXTREFSEL and REFSEL registers as shown in the following figure. When AREF is selected in the REFSEL register, the EXTREFSEL register is used to select one of the AIN0-AIN7 analog input pins as reference input. The selected analog pins will be acquired by the comparator once it is enabled.
When the comparator core detects that VIN+ > VIN-, i.e. ABOVE as per the RESULT register, VIN- will switch to VDOWN. When VIN+ falls below VIN- again, VIN- will be switched back to VUP. By specifying VUP larger than VDOWN, a hysteresis can be generated as illustrated in the following figures.
Writing to HYST has no effect in single-ended mode, and the content of this register is ignored.
