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.
