Mnemonic Description
AGND Analog GND Pins.
AV
CC
Analog Supply Pins. Voltage range from 4.75 V to 5.25 V.
V
PP
Output Amplifier High Voltage Supply. Voltage range from (REF_IN × 50) + 1 V to 225 V.
V
+
V
+
Amplifier Supply Pins. Voltage range from 4.75 V to 5.25 V.
PGND Output Amplifier Ground Reference Pins.
DGND Digital GND Pins.
DV
CC
Digital Supply Pins. Voltage range from 2.7 V to 5.25 V.
DAC_GND Reference GND Supply for All DACs.
REF_IN Reference Voltage for Channel 0 to Channel 31. Reference input range is 1 V to 4 V and can be used to program the full-
scale output voltage from 50 V to 200 V.
V
OUT
0 to V
OUT
31 Analog Output Voltages from the 32 Channels.
ANODE Anode of Internal Diode for Diode Temperature Measurement.
CATHODE Cathode of Internal Diode for Diode Temperature Measurement.
SYNC
Active Low Input. This is the frame synchronization signal for the serial interface. While
SYNC
is low, data is transferred in
upon the falling edge of SCLK.
SCLK Serial Clock Input. Data is clocked into the shift register upon the falling edge of SCLK. The pin operates at clock speeds of
up to 30 MHz. Internal pull-up device on logic input; therefore, it can be left floating and defaults to a logic high
condition.
D
IN
Serial Data Input. Data must be valid upon the falling edge of SCLK.
TEST For normal operation, tie this pin low.
RESET
Active Low Input. This pin can also be used to reset the complete device to its power-on reset conditions. Zero code is
loaded to the DACs.
NC No Connect. Do not connect to these pins.
