Description
1
VDD
Power Supply Input. These parts can be operated from 2.5 V to 5.5 V and the supply can be decoupled to GND.
2
VOUTA
Buffered Analog Output Voltage from DAC A. The output amplifier has rail-to-rail operation.
3
VOUTB
Buffered Analog Output Voltage from DAC B. The output amplifier has rail-to-rail operation.
4
VOUTC
Buffered Analog Output Voltage from DAC C. The output amplifier has rail-to-rail operation.
5
REFIN
Reference Input Pin for All Four DACs. It has an input range from 0.25 V to VDD.
6
VOUTD
Buffered Analog Output Voltage from DAC D. The output amplifier has rail-to-rail operation.
7
GND
Ground Reference Point for All Circuitry on the Part.
8
DIN
Serial Data Input. This device has a 16-bit shift register. Data is clocked into the register on the falling edge of the
serial clock input. The DIN input buffer is powered down after each write cycle.
9
SCLK
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 clock speeds up to 30 MHz. The SCLK input buffer is powered down after each write cycle.
10
SYNC
Active Low Control Input. 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 16 clocks. If SYNC is
taken high before the 16th falling edge of SCLK, the rising edge of SYNC acts as an interrupt and the write
sequence is ignored by the device.
Exposed
Paddle1
Ground Reference Point for All Circuitry on the Part. Can be connected to 0 V or left unconnected provided there is
a connection to 0 V via the GND pin.
1 For the 10-Lead LFCSP only.
