# LME49726MY

**Texas Instruments** · Audio Amplifiers · MSOP-8-EP

LME49726MY from Texas Instruments, in a MSOP-8-EP. 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 | OUTPUTA | output | Output of amplifier A, which easily drives 2 kΩ loads to within 4 mV of either power supply rail. |
| 2 | INVERTING INPUT A | input | Inverting input of amplifier A; the common-mode input range is VSS + 0.1 V to VDD − 1.6 V. |
| 3 | NON-INVERTING INPUT A | input | Non-inverting input of amplifier A; the common-mode input range is VSS + 0.1 V to VDD − 1.6 V. |
| 4 | VSS | power_in | Negative supply rail, 0.0 V in the electrical characteristics conditions; the device runs from 2.5 V to 5.5 V single supply or ±1.25 V to ±2.75 V dual supply. |
| 5 | NON-INVERTING INPUT B | input | Non-inverting input of amplifier B; the common-mode input range is VSS + 0.1 V to VDD − 1.6 V. |
| 6 | INVERTING INPUT B | input | Inverting input of amplifier B; the common-mode input range is VSS + 0.1 V to VDD − 1.6 V. |
| 7 | OUTPUTB | output | Output of amplifier B, which easily drives 2 kΩ loads to within 4 mV of either power supply rail. |
| 8 | VDD | power_in | Positive supply rail; operating range is 2.5 V to 5.5 V and the absolute maximum supply voltage VS is 6 V. |
| 9 | EP | passive | Exposed thermal pad (PowerPAD) on the underside of the package, shown as pin 9 in the land pattern; the datasheet does not state a net connection for it. |
