Description
Power Supply Input. These parts can operate from 2.7 V to 5.5 V. V
Reference Voltage Output.
Feedback Connection for the Output Amplifier. V
Analog Output Voltage from DAC. The output amplifier has rail-to-rail operation.
Level-Triggered Control Input (Active Low). This is the frame synchronization signal for the input data. When
SYNC goes low, it enables the input shift register and data is transferred in on the falling edges of the following
clocks. The DAC is updated following the 24
AD5620/AD5640 unless SYNC is taken high before this edge. In this case, the rising edge of SYNC acts as an
interrupt, and the write sequence is ignored by the DAC.
Serial Clock Input. Data is clocked into the input shift register on the falling edge of the serial clock input. Data
can be transferred at rates up to 30 MHz.
Serial Data Input. The AD5660 has a 24-bit shift register, and the AD5620/AD5640 have a 16-bit shift register.
Data is clocked into the register on the falling edge of the serial clock input.
Ground Reference Point for all Circuitry on the Part.
