LPC660AIMX from Texas Instruments, in a SOIC-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	OUTPUT 1	output	Amplifier 1 output with rail-to-rail swing; do not connect to V+ when V+ is above 13V and avoid loads below 500 Ω.
2	INPUT 1-	input	Amplifier 1 inverting input with ultra-low input bias current, absolute max input current ±5 mA.
3	INPUT 1+	input	Amplifier 1 non-inverting input whose common-mode range includes ground, absolute max input current ±5 mA.
4	V+	power_in	Positive supply, operating range 4.75V to 15.5V (16V absolute maximum between V+ and V-).
5	INPUT 2+	input	Amplifier 2 non-inverting input whose common-mode range includes ground, absolute max input current ±5 mA.
6	INPUT 2-	input	Amplifier 2 inverting input with ultra-low input bias current, absolute max input current ±5 mA.
7	OUTPUT 2	output	Amplifier 2 output with rail-to-rail swing; do not connect to V+ when V+ is above 13V and avoid loads below 500 Ω.
8	OUTPUT 3	output	Amplifier 3 output with rail-to-rail swing; do not connect to V+ when V+ is above 13V and avoid loads below 500 Ω.
9	INPUT 3-	input	Amplifier 3 inverting input with ultra-low input bias current, absolute max input current ±5 mA.
10	INPUT 3+	input	Amplifier 3 non-inverting input whose common-mode range includes ground, absolute max input current ±5 mA.
11	V-	power_in	Negative supply or ground for single-supply operation; input and output pins must stay within 0.3V of the supply rails.
12	INPUT 4+	input	Amplifier 4 non-inverting input whose common-mode range includes ground, absolute max input current ±5 mA.
13	INPUT 4-	input	Amplifier 4 inverting input with ultra-low input bias current, absolute max input current ±5 mA.
14	OUTPUT 4	output	Amplifier 4 output with rail-to-rail swing; do not connect to V+ when V+ is above 13V and avoid loads below 500 Ω.
