ACT2861

30V Buck-Boost Charger with Integrated MOSFETs and OTG

REG 0x09: ADC Configuration 1 (R/W) (VM)

Bit

Name

Description

Comment

EN_ADC

0: ADC disabled

1: ADC enabled

ADC_ONE_SHOT

0: ADC continually

converts data when

EN_ADC=1

1: ADC performs a one-

time conversion when

EN_ADC=1

[ADC ONE SHOT][ADC_ CH_SCAN] = XX operation is

described as below.

00 = Scan channel specified by ADC CHANNEL

CONVERSION [2:0] register bits repeatedly in a loop.

01 = Scan and convert channels 0 – 7 repeatedly in a loop.

10 = Convert channel specified by ADC CHANNEL

CONVERSION [2:0] once (one shot)

11 = Scan and convert channels 0 – 7 once and stop – one

loop

ADC_CH_SCAN

0: Scan single channel

specified by

ADC_CH_CONV

1: Scan all channels

DIS_ADC_BUFFER

0: ADC Buffer is

enabled

1: ADC Buffer is

disabled

This should always be set to 0.

ADC_SWAP

0: ADC Buffer is normal

inputs

1: ADC Buffer swaps

inputs

If very accurate measurements are required, the ADC input

pair can be swapped to negate input offset errors in the

Buffer AMP. This requires one read with ADC_SWAP=0

and one read with ADC_SWAP=1, then average the results.
