XINLUDA · Audio Amplifiers · DIP-14

XD3403 from XINLUDA, in a DIP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT1 output Output of amplifier 1, short-circuit protected, with output range that includes the negative supply.
2 IN1- input Inverting input of amplifier 1 (true differential input; common-mode range includes the negative supply).
3 IN1+ input Non-inverting input of amplifier 1 (true differential input; common-mode range includes the negative supply).
4 VCC power_in Positive supply, 3.0 V to 36 V single supply or +1.5 V to +18 V split supply (absolute maximum 36 V single, ±18 V split).
5 IN2+ input Non-inverting input of amplifier 2 (true differential input).
6 IN2- input Inverting input of amplifier 2 (true differential input).
7 OUT2 output Output of amplifier 2, short-circuit protected.
8 OUT3 output Output of amplifier 3, short-circuit protected.
9 IN3- input Inverting input of amplifier 3 (true differential input).
10 IN3+ input Non-inverting input of amplifier 3 (true differential input).
11 VEE/GND power_in Negative supply or ground for single-supply operation; -1.5 V to -18 V in split-supply operation.
12 IN4+ input Non-inverting input of amplifier 4 (true differential input).
13 IN4- input Inverting input of amplifier 4 (true differential input).
14 OUT4 output Output of amplifier 4, short-circuit protected.
