AD5422BREZ-REEL from Analog Devices, in a HTSSOP-24. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	AVSS	power_in	Negative analog supply. Range −3 V to −24 V. May be tied to 0 V when only a unipolar output range is used.
2	DVCC	power_in	Digital supply. Range 2.7 V to 5.5 V. Leave floating if the internal 4.5 V LDO is used (DVCC SELECT tied to GND) so this pin can be driven by the internal LDO output.
3	FAULT	output	Fault alert, active-low, open-drain output. Asserted when an open circuit is detected in current mode or when an over-temperature condition is detected. Requires an external pull-up.
4	GND	power_in	Ground reference pin (0 V).
5	CLEAR SELECT	input	Selects the voltage-output clear code loaded on a CLEAR event: zero scale or mid-scale (see Table 21).
6	CLEAR	input	Active-high asynchronous clear input. Assertion drives the current output to the low end of the selected range and the voltage output to the user-selected value (zero or mid-scale).
7	LATCH	input	Positive-edge sensitive latch. On the rising edge, the contents of the input shift register are transferred into the DAC register and the output updates.
8	SCLK	input	Serial clock input. Data is shifted into the input register on the rising edge of SCLK. Maximum clock rate 30 MHz.
9	SDIN	input	Serial data input. Data must be valid on the rising edge of SCLK.
10	SDO	output	Serial data output. Used to daisy-chain multiple devices or to read back the shift register contents. Data is clocked out on the rising edge of SCLK (see Figure 3, Figure 4).
11	GND	power_in	Ground reference pin (0 V).
12	GND	power_in	Ground reference pin (0 V).
13	RSET	passive	Optional external precision, low-drift 15 kΩ current-set resistor connection. Using an external RSET improves the IOUT temperature drift performance.
14	REFOUT	output	On-chip 5 V ± 2 mV precision reference output.
15	REFIN	input	External reference voltage input. Input range 4 V to 5 V; use REFIN = 5 V to achieve rated performance.
16	DVCC SELECT	input	When tied to GND, the internal supply is disabled and an external supply must be connected to DVCC. Leave unconnected to enable the internal 4.5 V LDO on DVCC.
17	CCOMP	passive	Optional voltage-output compensation capacitor connection. Connecting a 4 nF cap between CCOMP and VOUT allows driving up to 1 µF capacitive loads at the expense of output amplifier bandwidth and settling time.
18	NC	unconnected	No connect. Do not connect to this pin.
19	IOUT	output	Current output pin. Programmable 4-20 mA, 0-20 mA or 0-24 mA current-loop output.
20	BOOST	output	Optional external boost transistor connection. Connecting an external pass transistor reduces power dissipation in the AD5412/AD5422.
21	VOUT	output	Buffered analog voltage output. The output amplifier can drive a 1 kΩ / 2000 pF load directly.
22	+VSENSE	input	Positive load-sense (Kelvin) connection for the voltage output.
23	-VSENSE	input	Negative load-sense (Kelvin) connection for the voltage output.
24	AVDD	power_in	Positive analog supply. Range 10.8 V to 60 V.
25	EPAD	passive	Exposed thermal pad. May be tied to 0 V for unipolar output ranges, or left electrically unconnected when a supply connection is already made at AVSS. Thermally connect to a copper plane for improved heat dissipation.
