LM2904QS-13

Diodes Incorporated · Operational Amplifier · SO-8

LM2904QS-13 from Diodes Incorporated, in a SO-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 1OUT output Channel 1 output. Op-amp output stage capable of sourcing/sinking up to ~40mA (typ short-circuit), swinging from ~0V to VCC-1.5V.
2 1IN- input Channel 1 inverting input. High-impedance input with typical input bias current of -20nA (PNP input stage sources current out of the pin).
3 1IN+ input Channel 1 non-inverting input. Input common-mode voltage range includes ground (0V to VCC-1.5V); tolerates up to +36V without damage.
4 GND power_in Ground / negative supply. In single-supply operation this is 0V; in dual-supply operation this connects to the negative rail (down to -18V relative to VCC).
5 2IN+ input Channel 2 non-inverting input. Input common-mode voltage range includes ground (0V to VCC-1.5V); tolerates up to +36V without damage.
6 2IN- input Channel 2 inverting input. High-impedance input with typical input bias current of -20nA (PNP input stage sources current out of the pin).
7 2OUT output Channel 2 output. Op-amp output stage capable of sourcing/sinking up to ~40mA (typ short-circuit), swinging from ~0V to VCC-1.5V.
8 VCC power_in Chip positive supply voltage. Single supply 3V to 36V, or positive rail of dual supply ±1.5V to ±18V. Bypass with 0.1µF ceramic close to pin.
