Description
1.8 V Digital Supply.
Serial Programming Clock. Data clock for serial programming. SCLK is used for
SPI mode, and SCL is used for I
Serial Data Input/Output. When the device is in 4-wire mode, data is written
via this pin. In 3-wire mode, both data reads and writes occur on this pin.
There is no internal pull-up/pull-down resistor on this pin.
Serial Data Output. Use this pin to read data in 4-wire mode (high impedance
in 3-wire mode). There is no internal pull-up/pull-down resistor on this pin.
SPI Mode.
Chip Select (CS) Input. Active low. When programming a device, this pin must
be held low. In systems where more than one AD9547 is present, this pin enables
individual programming of each AD9547. In SPI mode, this pin has an internal
30 kΩ pull-up resistor.
I
Serial Data Line (SDA) Input/Output. In I
read operations and an input during write operations. There is no internal
pull-up resistor in I
3.3 V I/O Digital Supply.
Chip Reset. Assertion of this pin (active high) resets the device. This pin has an
internal 50 kΩ pull-down resistor.
1.8 V DAC Decode Digital Supply. Isolate the supply associated with these
DVDD pins from the supply associated with the other DVDD pins.
Analog Ground. Connect to ground.
DAC Output. DACOUTP contains an internal 50 Ω pull-down resistor.
Complementary DAC Output. DACOUTN contains an internal 50 Ω pull-down
resistor.
3.3 V Analog (DAC) Power Supply.
1.8 V Analog (DAC) Power Supply.
