OPA2314M

HGSEMI · Operational Amplifier · SOP-8

OPA2314M from HGSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTA output Output of amplifier A. Rail-to-rail output stage; can swing within ~2mV of the supply rails into >100kΩ loads, ~60mV into 10kΩ. Typical closed-loop output impedance 10Ω at 100kHz, output current ~53mA (typ).
2 INA- input Inverting input of amplifier A. High-impedance CMOS input with ~1pA typical bias current. Input voltage range: VSS-0.5V to VDD+0.5V (absolute max); common-mode range extends 100mV beyond the rails.
3 INA+ input Non-inverting input of amplifier A. High-impedance CMOS input with ~1pA typical bias current. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V).
4 VSS power_in Negative supply / ground pin. Connect to GND for single-supply operation (2.1V to 5.5V) or to the negative rail for dual-supply operation (±1.05V to ±2.75V). Bypass with 0.1µF ceramic capacitor for dual-supply use.
5 INB+ input Non-inverting input of amplifier B. High-impedance CMOS input with ~1pA typical bias current. Rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V).
6 INB- input Inverting input of amplifier B. High-impedance CMOS input with ~1pA typical bias current. Absolute-max input range: VSS-0.5V to VDD+0.5V.
7 OUTB output Output of amplifier B. Rail-to-rail output stage; ~2mV from rail into >100kΩ, ~60mV into 10kΩ. Output current ~53mA (typ), closed-loop output impedance 10Ω at 100kHz.
8 VDD power_in Positive supply pin. Operating range 2.1V to 5.5V (absolute max VDD-VSS = 7.5V). Bypass with a 0.1µF ceramic capacitor placed close to the pin for best performance.
