STLUX385A

Product overview

of 1 or 4 times. The analog-to-digital converter can operate either in single or in

continuous/circular modes. The ADC unit has the following main features:

•

8 ADC input channel

•

10-bit resolution

•

Single and continuous conversion mode

•

Independent channel gain value x1 or x4 to extend dynamic range and resolution to 12-

bit equivalent

•

Interrupt events:

–

EoC interrupt asserted on end of conversion cycle

–

EoS interrupt asserted on end of conversion sequences

–

SEQ_FULL_EN interrupt assert on sequencer buffer full

•

ADC input voltage range dependent on selected gain value

•

Selectable conversion data alignment

•

Individual registers for up to 8 successive conversions

Analog comparators

The STLUX385A includes four independent fast analog comparator units (COMP3-0). Each

comparator has an internal reference voltage. COMP3 can be also configured to use an

external reference voltage connected to CPM3 input pin.

Each comparator reference voltage is generated by a dedicated internal-only 4-bit DAC unit.

The main characteristics of the analog comparator unit (ACU) are the following:

•

Each comparator has an internally configurable reference

•

Internal reference voltages configurable in 16 steps with 83 mV voltage grain from 0 V

(GND) to 1.24 V (voltage reference)

•

Two stage comparator architecture is used to reach a high gain

•

Comparator output stage value accessible from processor interface

•

Continuous fast cycle comparison time
