DESCRIPTION

NAME

PWP

(HTSSOP)

RHA

(VQFN)

ALARM

Digital output

Alarm pin. Open drain output. External pullup resistor required (10 kΩ). The

pin goes low (active) when the ALARM condition is detected (open circuit, over

temperature, timeout and so forth).

AVDD

Supply input

Positive analog power supply.

AVSS

14, 37

Supply input

Negative analog power supply in dual power-supply operation. Connects to GND

in single power-supply operation.

BOOST

Analog output Boost pin. External transistor connection (optional).

CAP1

—

Analog input Connection for current output filtering capacitor (optional).

CAP2

—

Analog input Connection for current output filtering capacitor (optional).

CLR

Digital input

Clear input. Logic high on this pin causes the part to enter CLEAR state. Active

high.

CLR-SEL

Digital input

Selects the VOUT value in CLEAR state, after power-on and reset.

CMP

Analog output

External compensation capacitor connection pin (optional). Addition of the

external capacitor (connected between VOUT and this pin) improves the stability

with high capacitive loads at the VOUT pin by reducing the bandwidth of the

output amplifier, thus increasing the settling time. If an external compensation

capacitor greater than 470 pF is used, connect an additional 100-pF capacitor

from CMP to GND.

DIN

Digital input

Serial data input. Data are clocked into the 24-bit input shift register on the rising

edge of the serial clock input. Schmitt-Trigger logic input.

DVDD

Supply input

or output

Digital power supply. Can be input or output, depending on DVDD-EN pin.

DVDD-EN

Digital input

Internal power-supply enable pin. Connect this pin to GND to disable the internal

supply, or leave this pin unconnected to enable the internal supply. When this pin

is connected to GND, an external supply must be connected to the DVDD pin.

GND

Supply input

Ground reference point for all digital circuitry of the device. Connect to 0 V.

GND

11, 12

12, 13, 15

Supply input

Ground reference point for all analog circuitry of the device. Connect to 0 V.

HART-IN

Analog input Input pin for HART modulation.

IOUT

Analog output Current output pin

ISET-R

Analog input Connection pin for external precision resistor (15 kΩ); see Section 8.

LATCH

Digital input

Load DAC registers input. A rising edge on this pin loads the input shift register

data into the DAC data and control registers and updates the DAC outputs.

—

No connection.

REFOUT

Analog output Internal reference output. Connect to REFIN when using internal reference.

REFIN

Analog input Reference input

SCLK

Digital input

Serial clock input of serial peripheral interface (SPI). Data can be transferred at

rates up to 30 MHz. Schmitt-Trigger logic input.

SDO

Digital output Serial data output. Data are valid on the rising edge of SCLK.

Thermal

Pad

—

Supply input

The thermal pad is internally connected to the AVSS supply. For enhanced

thermal performance, thermally connect the pad to a copper plane. The pad

can be electrically connected to the same potential as the AVSS pin (either

negative supply voltage or GND) or left electrically unconnected provided a supply

connection is made at the AVSS pin. The AVSS pin must always be connected

to either the negative supply voltage or GND, independent of the thermal pad

connection.

VOUT

Analog output Voltage output pin. This is a buffered analog voltage output.

+VSENSE

Analog input Sense pin for the positive voltage output load connection.

–VSENSE

Analog input Sense pin for the negative voltage output load connection.
