Glossary
Crosspoint connection
Connection between any GPIO combination via analog multiplexer bus.
Differential non-linearity
Ideally, any two adjacent digital codes correspond to output analog voltages that are exactly
one LSB apart. Differential non-linearity is a measure of the worst case deviation from the
ideal 1 LSB step.
Hold time
I²C
Hold time is the time following a clock event during which the data input to a latch or flip-
flop must remain stable in order to guarantee that the latched data is correct.
It is a serial multi-master bus used to connect low speed peripherals to MCU.
Integral nonlinearity
It is a term describing the maximum deviation between the ideal output of a DAC/ADC and
the actual output level.
Latch up current
Current at which the latch up test is conducted according to JESD78 standard (at 125 °C)
Power supply rejection ratio (PSRR) The PSRR is defined as the ratio of the change in supply voltage to the corresponding
change in output voltage of the device.
Scan
The conversion of all sensor capacitances to digital values.
Setup time
Period required to prepare a device, machine, process, or system for it to be ready to
function.
Signal-to-noise ratio
The ratio between a capacitive finger signal and system noise.
SPI
Serial peripheral interface is a synchronous serial data link standard.
