(1)
Description
1
VD1
AI
Supply voltage for LED D1
2
VD3
AI
Connection to current sink 3
3
GND
G
Power supply ground. All voltages are
referenced to GND.
4
ECG_INP
AI
ECG amplifier positive input
5
ECG_INN
AI
ECG amplifier negative input
6
ECG_REF
AO
ECG amplifier reference output
7
ENABLE
DI
Enable input for AS7030B. Active high.
Setting this input to low resets all internal
registers and the AS7030B enters power
down mode. Setting it high allows
operation of the AS7030B.
If ENABLE is not used (AS7030B always
enabled), connect to VDD.
8
INT
DO
Open drain interrupt output pin. Active
low.
9
SCL
DI
I²C serial clock input terminal
– the device
does not use clock stretching therefore
SCL is only an input terminal.
10
SDA
DIO
I²C serial data I/O terminal
– open drain.
11
NC
Not connect
12
VDD
P
Supply voltage. Connect a 2.2
μF
capacitor to GND.
13
GPIO0
GPIO
General purpose input/output
14
GPIO1
GPIO
General purpose input/output
15
GPIO2
GPIO
General purpose input/output
16
GPIO3
GPIO
General purpose input/output
17
V_LDO
AO
1.9 V output voltage. Connect 2.2
μF
capacitor to GND
(e.g. 0402 sized capacitor
GRM153R60J225ME95 or 0201 sized
GRM033R60J225ME47 from Murata
–
needs to have >1
μF with 1.0 V voltage
bias); do not load externally
18
AGND
GND
Analog ground. Connect to low noise
GND
