OPA4353UA

Texas Instruments · Operational Amplifier · SOIC-14

OPA4353UA 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	Out A	output	Output of amplifier A, rail-to-rail output swinging within 10mV of the supply rails with a 10kΩ load.
2	-In A	input	Inverting input of amplifier A; diode-clamped to supply rails, current-limit to 10mA if signals swing more than 0.3V beyond the rails.
3	+In A	input	Non-inverting input of amplifier A; rail-to-rail input with common-mode range extending 0.1V beyond the supplies, diode-clamped, limit to 10mA beyond 0.3V.
4	V+	power_in	Positive supply, operating range 2.7V to 5.5V (absolute maximum supply 5.5V), minimum operating voltage 2.5V.
5	+In B	input	Non-inverting input of amplifier B; rail-to-rail input, diode-clamped to the supply rails.
6	-In B	input	Inverting input of amplifier B; diode-clamped to the supply rails, limit to 10mA if beyond 0.3V outside rails.
7	Out B	output	Output of amplifier B, rail-to-rail output with ±40mA output current and ±80mA short-circuit current.
8	Out C	output	Output of amplifier C, rail-to-rail output with ±40mA output current and ±80mA short-circuit current.
9	-In C	input	Inverting input of amplifier C; diode-clamped to the supply rails, limit to 10mA if beyond 0.3V outside rails.
10	+In C	input	Non-inverting input of amplifier C; rail-to-rail input, diode-clamped to the supply rails.
11	V-	power_in	Negative supply or ground in single-supply operation; input and output signals are referenced to this rail.
12	+In D	input	Non-inverting input of amplifier D; rail-to-rail input, diode-clamped to the supply rails.
13	-In D	input	Inverting input of amplifier D; diode-clamped to the supply rails, limit to 10mA if beyond 0.3V outside rails.
14	Out D	output	Output of amplifier D, rail-to-rail output with ±40mA output current and ±80mA short-circuit current.
