MD1622 from Shanghai Mingda Microelectronics, in a SOP-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 VOUTA output Channel A rail-to-rail output, able to source/sink about 90mA at VDD = 5V.
2 VINA- input Channel A inverting input, common-mode range -0.1V to +5.6V with VDD - VSS = 5.5V.
3 VINA+ input Channel A non-inverting input, common-mode range -0.1V to +5.6V with VDD - VSS = 5.5V.
4 VSS power_in Negative supply (ground in single-supply operation).
5 VINB+ input Channel B non-inverting input, common-mode range -0.1V to +5.6V with VDD - VSS = 5.5V.
6 VINB- input Channel B inverting input, common-mode range -0.1V to +5.6V with VDD - VSS = 5.5V.
7 VOUTB output Channel B rail-to-rail output, able to source/sink about 90mA at VDD = 5V.
8 VDD power_in Positive supply, 1.8V to 5.5V operating range (6V absolute maximum between VDD and VSS).
