Description

Device Addressing Bit (AD0). In software mode, this pin, in conjunction with AD1 and AD2, allows up to eight

devices to be addressed on one bus.

Range Decode Bit (R3). In hardware mode, this pin, in conjunction with R0, R1, and R2, selects the output

current/voltage range setting on the part.

A 15 kΩ external current setting resistor can be connected between the REXT1 and REXT2 pins to improve the

IOUT temperature drift performance.

Buffered Reference Input.

Buffered Analog Input (0 V to 4.096 V).

Ground Connection.

Positive Analog Supply.

Current Output.

Optional Compensation Capacitor Connections for the Voltage Output Buffer. These pins are used to drive

higher capacitive loads on the output. They also reduce overshoot on the output. Care should be taken when

choosing the value of the capacitor connected between the COMP1 and COMP2 pins because it has a direct

influence on the settling time of the output. See the Driving Large Capacitive Loads section for further details.

Negative Analog Supply.

Sense Connection for the Negative Voltage Output Load Connection. This pin must stay within ±3.0 V of

ground for correct operation.

Buffered Analog Output Voltage.

Sense Connection for the Positive Voltage Output Load Connection.

No Connect. Can be tied to GND.

EPAD

This pin is used to configure the part to hardware or software mode. HW SELECT = 0 selects software control,

and HW SELECT = 1 selects hardware control.

Resets the part to its power-on state.

Fault Alert (FAULT). In software mode, this pin acts as a general fault alert pin. It is asserted low when an open-

circuit error, short-circuit error, overtemperature error, or PEC interface error is detected. This pin is an open-

drain output and must be connected to a pull-up resistor.

Overtemperature Fault (TEMP). In hardware mode, this pin acts as an overtemperature fault pin. It is asserted

low when an overtemperature error is detected. This pin is an open-drain output and must be connected to a

pull-up resistor.

No Connect (NC). In software mode, this pin is a no connect. Instead, tie this pin to GND.

Open-Circuit Fault Alert (IFAULT). In hardware mode, this pin acts as an open-circuit fault alert pin. It is asserted

low when an open-circuit error is detected. This pin is an open-drain output and must be connected to a pull-

up resistor.

The exposed paddle is tied to AVSS.
