OA4ZHA33Q

STMicroelectronics · Precision Op Amps · QFN-16-EP(3x3)

OA4ZHA33Q from STMicroelectronics, in a QFN-16-EP(3x3). 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	IN1+	input	Non-inverting input of amplifier 1, rail-to-rail with common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V and input current to be limited to 10 mA.
2	VCC+	power_in	Positive supply, 1.8 V to 5.5 V operating range (6 V absolute maximum), decoupled with 0.1 µF close to the pin.
3	NC	unconnected	No internal connection.
4	IN2+	input	Non-inverting input of amplifier 2, rail-to-rail with common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V.
5	IN2-	input	Inverting input of amplifier 2, rail-to-rail with common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V.
6	OUT2	output	Rail-to-rail output of amplifier 2, within 30 mV of the rails with a 10 kΩ load to VCC/2.
7	OUT3	output	Rail-to-rail output of amplifier 3, within 30 mV of the rails with a 10 kΩ load to VCC/2.
8	IN3-	input	Inverting input of amplifier 3, rail-to-rail with common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V.
9	IN3+	input	Non-inverting input of amplifier 3, rail-to-rail with common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V.
10	NC	unconnected	No internal connection.
11	VCC-	power_in	Negative supply (ground in single-supply use).
12	IN4+	input	Non-inverting input of amplifier 4, rail-to-rail with common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V.
13	IN4-	input	Inverting input of amplifier 4, rail-to-rail with common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V.
14	OUT4	output	Rail-to-rail output of amplifier 4, within 30 mV of the rails with a 10 kΩ load to VCC/2.
15	OUT1	output	Rail-to-rail output of amplifier 1, within 30 mV of the rails with a 10 kΩ load to VCC/2.
16	IN1-	input	Inverting input of amplifier 1, rail-to-rail with common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V.
17	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
