Description
1, 4, 5, 12
3, 4, 14, 15, 37
GND
These pins must be connected to ground.
2
39
DVCC
Digital Supply Pin. Voltage ranges from 2.7 V to 5.5 V.
3
2
FAULT
Fault Alert. This pin is asserted low when an open circuit is detected between IOUT and
GND or an overtemperature is detected. The FAULT pin is an open-drain output and
must be connected to DVCC through a pull-up resistor (typically 10 kΩ).
6
5
CLEAR
Active High Input. Asserting this pin sets the output current to the zero-scale value,
which is either 0 mA or 4 mA, depending on the output range programmed, that is, 0 mA
to 20 mA, 0 mA to 24 mA, or 4 mA to 20 mA.
7
6
LATCH
Positive Edge Sensitive Latch. A rising edge parallel loads the input shift register data
into the relevant register. In the case of the data register, the output current is also
updated.
8
7
SCLK
Serial Clock Input. Data is clocked into the input shift register on the rising edge of
SCLK. This operates at clock speeds of up to 30 MHz.
9
8
SDIN
Serial Data Input. Data must be valid on the rising edge of SCLK.
10
9
SDO
Serial Data Output. This pin is used to clock data from the device in daisy-chain or
readback mode. Data is clocked out on the falling edge of SCLK. See Figure 3 and
11
12, 13
GND
Ground Reference Pin.
13
16
RSET
An external, precision, low drift 15 kΩ current setting resistor can be connected to this
pin to improve the overall performance of the device. See the Specifications and
14
17
REFOUT
Internal Reference Voltage Output. VREFOUT = 5 V ± 5 mV at TA = 25°C. Typical temperature
drift is 1.8 ppm/°C.
15
18
REFIN
External Reference Voltage Input. VREFIN = 5 V ± 50 mV for specified performance.
16
23
DVCC
SELECT
This pin, when connected to GND, disables the internal supply, and an external supply
must be connected to the DVCC pin. Leave this pin unconnected to enable the internal
