AD5541 PIN FUNCTION DESCRIPTIONS
Description
Analog Output Voltage from the DAC.
Ground Reference Point for Analog Circuitry.
This is the voltage reference input for the DAC. Connect to external 2.5 V reference.
Reference can range from 2 V to VDD.
This is a logic input signal. The chip select signal is used to frame the serial data input.
Clock Input. Data is clocked into the input register on the rising edge of SCLK. Duty cycle
must be between 40% and 60%.
Serial Data Input. This device accepts 16-bit words. Data is clocked into the input register on
the rising edge of SCLK.
Digital Ground. Ground reference for digital circuitry.
Analog Supply Voltage, 5 V ± 10%.

AD5542 PIN FUNCTION DESCRIPTIONS
Description
Feedback Resistor. In bipolar mode connect this pin to external op amp output.
Analog Output Voltage from the DAC.
Ground Reference Point for Analog Circuitry (Force).
Ground Reference Point for Analog Circuitry (Sense).
This is the voltage reference input (sense) for the DAC. Connect to external 2.5 V reference.
Reference can range from 2 V to VDD.

No Connect.
Serial Data Input. This device accepts 16-bit words. Data is clocked into the input register on
the rising edge of SCLK.
LDAC Input. When this input is taken low, the DAC register is simultaneously updated with
the contents of the input register.
Digital Ground. Ground reference for digital circuitry.
Connected to the Internal Scaling Resistors of the DAC. Connect INV pin to external op amps
inverting input in bipolar mode.
Analog Supply Voltage, 5 V ± 10%.
