Description
These pins must be connected to 0V.
Digital Supply Pin. Voltage ranges from 2.7 V to 5.5 V.
Fault alert, This pin is asserted low when an open circuit is detected in current mode or
an over temperature is detected. Open drain output, must be connected to a pull-up
resistor.
No Connection.
Active High Input. Asserting this pin will set the current output to the bottom of the
selected range.
Positive edge sensitive latch, a rising edge will parallel load the input shift register data
into the DAC register, also updating the output.
Serial Clock Input. Data is clocked into the shift register on the rising edge of SCLK. This
operates at clock speeds up to 30 MHz.
Serial Data Input. Data must be valid on the rising edge of SCLK.
Serial Data Output. Used to clock data from the serial register in daisy-chain or readback
mode. Data is clocked out on the falling edge of SCLK. See Figure 3 and Figure 4.
Ground reference pin for analog circuitry.
Ground reference pin for digital circuitry. (AGND and DGND are internally connected in
TSSOP package).
An external, precision, low drift 15kΩ current setting resistor can be connected to this
pin to improve the I
Internal Reference Voltage Output. REFOUT = 5 V ± 2 mV.
External Reference Voltage Input. Reference input range is 4 V to 5 V. REFIN = 5 V for
specified performance.
This pin when connected to GND disables the internal supply and an external supply
must be connected to the DV
supply. Refer to features section.
Current output pin.
Optional external transistor connection. Connecting an external transistor will reduce
the power dissipated in the AD5410/AD5420. Refer to the features section.
Connection for optional output filtering capacitor. Refer to Features section.
Connection for optional output filtering capacitor. Refer to Features section.
Positive Analog Supply Pin. Voltage ranges from 10.8V to 40V/60V.
Ground reference for analog circuitry.
