Description
10
AD1/R2
Device Addressing Bit (AD1). In software mode, this pin, in conjunction with AD0 and AD2, allows up to
eight devices to be addressed on one bus.
Range Decode Bit (R2). In hardware mode, this pin, in conjunction with R0, R1, and R3, selects the output
current/voltage range setting on the part.
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 k 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
GND
Ground Connection.
22
GND
Ground Connection.
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 part 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
In software mode, this pin resets the part to its power-on state. Active low.
In hardware mode, there is no reset. If using the part in hardware mode, the RESET pin should be tied
high.
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, short-circuit, 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 GND.
