Output Amplifier Ground Reference Pins.
Digital GND Pins.
Digital Supply Pins. Voltage range from 2.7 V to 5.25 V.
Reference GND Supply for All DACs.
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.
Analog Output Voltages from the 32 Channels.
Anode of Internal Diode for Diode Temperature Measurement.
Cathode of Internal Diode for Diode Temperature Measurement.
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.
Serial Clock Input. Data is clocked into the shift register upon the falling edge of SCLK. This operates at clock speeds of up
to 30 MHz.
Serial Data Input. Data must be valid upon the falling edge of SCLK.
Allows the same data to be simultaneously loaded to all channels of the AD5535. This pin is used for calibration purposes
when loading zero scale and full scale to all channels. To invoke this feature, bring the TEST pin high. In normal operation,
TEST should be tied low.
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.
No connect pins. The user should not connect any signals to these pins.
