LMH6646MMX from Texas Instruments, in a VSSOP-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 | Output of amplifier channel A; rail-to-rail, swings to within 20 mV of either supply rail at light loads with ±20 mA linear output current and 42 mA short-circuit sourcing capability. |
| 2 | -IN A | input | Inverting input of amplifier channel A; input common-mode range extends 0.3 V beyond either supply rail, 3 MΩ input resistance, 2 pF input capacitance, input voltage noise 17 nV/√Hz at 100 kHz. |
| 3 | +IN A | input | Non-inverting input of amplifier channel A; input common-mode range extends 0.3 V beyond either supply rail, 3 MΩ input resistance, 2 pF input capacitance. |
| 4 | V- | power_in | Negative supply pin; supports single or dual supply with total supply voltage (V+ − V−) from 2.5 V to 12 V; decouple with low-inductance ceramic capacitor placed within 0.5 inches of pin. |
| 5 | +IN B | input | Non-inverting input of amplifier channel B; input common-mode range extends 0.3 V beyond either supply rail, 3 MΩ input resistance, 2 pF input capacitance. |
| 6 | -IN B | input | Inverting input of amplifier channel B; input common-mode range extends 0.3 V beyond either supply rail, 3 MΩ input resistance, 2 pF input capacitance, input voltage noise 17 nV/√Hz at 100 kHz. |
| 7 | OUT B | output | Output of amplifier channel B; rail-to-rail, swings to within 20 mV of either supply rail at light loads with ±20 mA linear output current and 42 mA short-circuit sourcing capability. |
| 8 | V+ | power_in | Positive supply pin; supports total supply voltage (V+ − V−) from 2.5 V to 12 V, quiescent current 650 μA/channel typical at 2.7 V; decouple with low-inductance ceramic capacitor placed within 0.5 inches of pin. |
