TYPE
FUNCTION
VDD
1, 19, 20, 24
Power
Analog Supply (9.0V to 15.5V)
GND
2, 38, 40,
42, 43
Power
Ground
LD
3
Input
Latch Data Input. When LD is low, Latch B retains existing data (acts as a latch).
When LD is high, the input to Latch B data flows through to the output and updates
the DACs asynchronously.
S1
4
S0
5
Input
Select Inputs. When Control register [1,0] = 00, S0 and S1 pins are used to select
DAC input data from EEPROM.
SCL
6
Input
I2C Serial Clock Input
SDA
7
Input/Output
I2C Serial Data Input/Output
A0
8
Input
Address Input. This pin determines I2C slave address of the DS3510.
VCC
9
Power
Digital Supply (2.7V to 5.5V)
