8.4 GENERAL PURPOSE (GP) ADC
The PAN1740 is equipped with a high-speed ultra low power 10-bit general purpose Analog-
to-Digital Converter (GPADC). It can operate in unipolar (single ended) mode as well as in
bipolar (differential) mode. The ADC has its own voltage regulator (LDO) of 1.2 V, which
represents the full scale reference voltage.
Features
 10-bit dynamic ADC with 65 ns conversion time
 Maximum sampling rate 3.3 Msample/s
 Ultra low power (5 µA typical supply current at 100 ksample/s)
 Single-ended as well as differential input with two input scales
 Four single-ended or two differential external input channels
 Battery monitoring function
 Chopper function
 Offset and zero scale adjust
 Common-mode input level adjust
8.5 QUADRATURE DECODERS
This block decodes the pulse trains from a rotary encoder to provide the step and the direction
of the movement of an external device. Three axes (X, Y, Z) are supported.
The integrated quadrature decoder can automatically decode the signals for the X, Y and Z
axes of a HID input device, reporting step count and direction: the channels are expected to
provide a pulse train with 90 degrees phase difference; depending on whether the reference
channel is leading or lagging, the directioncan be determined.
This block can be used for waking up the chip as soon as there is any kind of movement from
the external device connected to it.
Features
 Three 16-bit signed counters that provide the step count and direction on each of
the axes (X, Y and Z)
 Programmable system clock sampling at maximum 16 MHz.
 APB interface for control and programming
 Programmable source from P0, P1 ports
 Digital filter on the channel inputs to avoid spikes
