I am using DAC7573 to read analog signal.
My configuration is as follows:
VDD = 5.0V; IOVDD=5.0V
A0 = GND; A1 = VDD; A2 = GND; A3 = GND; therefore addeess byte = 0x9C;
Operating mode: update selected DAC with I2C data: L1 =0; L2=1; PD0=0; therefore control byte for channels
channel A: 0x10
channel B: 0x11
channel C: 0x14
channel D: 0x16
data MSB: 0xFF
data LSB: 0xF0
Problem-1: Using the above configuration, though I can write data into DAC, however the output is not updated.
Problem-2: if I use A0=GND and A1=GND, then SCL & SDA lines are pulled down by the DAC.
Kindly help me to solve the problems.
