Description
Data Bit 0 (LSB), Negative.
1.8 V Digital Supply. Supplies power to digital core and digital data ports.
Active High Transmit Path Enable (CMOS). A low level on this pin clamps the DAC outputs to midscale.
Serial Port Data Input/Output (CMOS).
Serial Port Clock Input (CMOS).
Serial Port Chip Select, Active Low (CMOS).
Interrupt Request. Open-drain, active low output. Pull this pin high external to the device.
1.8 V Digital Supply. Supplies power to digital core and digital data ports.
Reset, Active Low (CMOS).
3.3 V Analog Supply.
Q DAC Positive Current Output.
Q DAC Negative Current Output.
3.3 V Analog Supply.
Analog Supply Common.
1.2 V Band Gap Voltage Reference Output. Should be decoupled to AVSS with a 0.1 µF capacitor.
Full-Scale Current Output Adjust. Place a 10 kΩ resistor from this pin to AVSS.
Analog Supply Common.
3.3 V Analog Supply.
I DAC Negative Current Output.
I DAC Positive Current Output.
3.3 V Analog Supply.
The exposed pad (EPAD) must be soldered to the ground plane (AVSS). The EPAD provides an electrical,
thermal, and mechanical connection to the board.
