# LMH6619MAX

**Texas Instruments** · Operational Amplifier · SOIC-8

LMH6619MAX from Texas Instruments, in a SOIC-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 A, which sources and sinks 35 mA and drives loads up to 30 pF without external compensation. |
| 2 | -IN A | input | Inverting input of amplifier A; the input common-mode range extends 200 mV beyond the supply rails. |
| 3 | +IN A | input | Non-inverting input of amplifier A; the input common-mode range extends 200 mV beyond the supply rails. |
| 4 | V- | power_in | Negative supply rail; the part operates over a 2.7 V to 11 V supply range. |
| 5 | +IN B | input | Non-inverting input of amplifier B; the input common-mode range extends 200 mV beyond the supply rails. |
| 6 | -IN B | input | Inverting input of amplifier B; the input common-mode range extends 200 mV beyond the supply rails. |
| 7 | OUT B | output | Output of amplifier B, which sources and sinks 35 mA and drives loads up to 30 pF without external compensation. |
| 8 | V+ | power_in | Positive supply rail; the part operates over a 2.7 V to 11 V supply range, with about 1.25 mA supply current per channel at 5 V. |
