TSSOP Pin No. LFCSP Pin No. Mnemonic Description
18 25 R3
SENSE
The voltage measured between this pin and the BOOST pin is directly proportional to
the output current and can be used as a monitor/feedback feature. This should be used
as a voltage sense output only; current should not be sourced from this pin. See the
AD5410/AD5420 Features section.
19 26 I
OUT
Current Output Pin.
20 27 BOOST
Optional External Transistor Connection. Connecting an external transistor reduces the
power dissipated in the AD5410/AD5420. See the AD5410/AD5420 Features section.
21 28 CAP1
Connection for Optional Output Filtering Capacitor. See the AD5410/AD5420 Features
section.
22 29 CAP2
Connection for Optional Output Filtering Capacitor. See the AD5410/AD5420 Features
section. Also HART Input Connection, see Device Features Section.
24 36 AV
DD
Positive Analog Supply Pin. Voltage ranges from 10.8 V to 40 V.
25 (EPAD) 41 (EPAD)
Exposed
pad
Ground Reference Connection. It is recommended that the exposed pad be thermally
connected to a copper plane for enhanced thermal performance.
