• Description: Data Conversion IC Development Tools I2C 8-BIT DAC DIGITAL-ANALOG CONV
• Manufacturer: Gravitech
• Type: DACr

Specifications of I2C-DAC

• Rohs: yes
• Product: Development Boards
• Tool Is For Evaluation Of: DAC5571
• Interface Type: I2C
• Operating Supply Voltage: 2.7 V to 5.5 V
• Description/function: 8-bit digital-to-analog converter

output, which gives an output range of 0 V
to VCC. It is capable of driving a load of 2
kΩ in parallel with 1000 pF to GND. The
source and sink capabilities of the output
amplifier can be seen in the typical
characteristics curves. The slew rate is 1
V/μs with a half-scale settling time of 7 μs
with the output unloaded.
Default
manufacture is 0x98 for write and 0x99 for
read.
A0 = GND
The address can be easily change by
solder the bridge between the A0 pin to
VCC or GND at the bottom of the module.
This is allows up to two devices to share

The green LED on the module is
illuminating when the power applied. The
power-on LED is enabled from the
manufacture. It can be disabling for light
sensitive or low current requirement
application by remove the solder bridge
on “PW” at the bottom of the module.
