OPA2348MM

HGSEMI · Operational Amplifier · MSOP-8

OPA2348MM from HGSEMI, in a MSOP-8. 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 Amplifier A output, rail-to-rail, swinging to within 18mV of the supply rail with a 100kΩ load.
2 -In A input Amplifier A inverting input; common-mode range (V-)-0.2V to (V+)+0.2V with input current limited to 10mA.
3 +In A input Amplifier A non-inverting input; common-mode range (V-)-0.2V to (V+)+0.2V with input current limited to 10mA.
4 V- power_in Negative supply (ground in single-supply use); supply range 2.1V to 5.5V total, 7.5V absolute maximum.
5 +In B input Amplifier B non-inverting input; common-mode range (V-)-0.2V to (V+)+0.2V with input current limited to 10mA.
6 -In B input Amplifier B inverting input; common-mode range (V-)-0.2V to (V+)+0.2V with input current limited to 10mA.
7 Out B output Amplifier B output, rail-to-rail, swinging to within 18mV of the supply rail with a 100kΩ load.
8 V+ power_in Positive supply, +2.1V to +5.5V operating (2.5V to 5.5V specified), 7.5V absolute maximum; bypass with 0.01µF ceramic capacitor.
