Pin No. Mnemonic Description
11 AD0/R3
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.
12, 13 REXT2, REXT1
A 15 kΩ external current setting resistor can be connected between the REXT1 and REXT2 pins to improve the
IOUT temperature drift performance.
14 VREF Buffered Reference Input.
15 VIN Buffered Analog Input (0 V to 4.096 V).
16 GND Ground Connection.
17 AVDD Positive Analog Supply.
18 IOUT Current Output.
19, 20
COMP2,
COMP1
Optional Compensation Capacitor Connections for the Voltage Output Buffer. These are used to drive higher
capacitive loads on the output. These pins 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.
21 AVSS Negative Analog Supply.
22 VSENSE−
Sense Connection for the Negative Voltage Output Load Connection. This pin must stay within ±3.0 V of
ground for correct operation.
23 VOUT Buffered Analog Output Voltage.
24 VSENSE+ Sense Connection for the Positive Voltage Output Load Connection.
25, 26,
27, 28
NC No Connect. Can be tied to GND.
29 HW SELECT This pin is used to configure the part to hardware or software mode.
HW SELECT = 0 selects software control.
HW SELECT = 1 selects hardware control.
30
RESET
Resets the part to its power-on state.
31 FAULT/TEMP
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.
32 NC/IFAULT 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.
33 (EPAD)
Exposed
paddle
The exposed paddle is tied to AVSS.
