LMV344IPWRQ1 from Texas Instruments, in a TSSOP-14. 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 | 1OUT | output | Output of amplifier 1, rail-to-rail; output swing is specified as tens of mV from the supply rails at RL = 2 kΩ and 10 kΩ, and short-circuit source/sink current is listed as IOS. |
| 2 | 1IN- | input | Inverting input of amplifier 1; input bias current is typically 1 pA at 25°C, and common-mode input range is -0.2 V to 4.2 V at V+ = 5 V (CMRR > 50 dB). |
| 3 | 1IN+ | input | Non-inverting input of amplifier 1; input offset voltage is typically 0.25 mV, and common-mode input range is -0.2 V to 4.2 V at V+ = 5 V (CMRR > 50 dB). |
| 4 | V+ | power_in | Positive supply pin; recommended single-supply operation is 2.5 V to 5.5 V and the absolute maximum supply voltage is 5.5 V. |
| 5 | 2IN+ | input | Non-inverting input of amplifier 2; input bias current is typically 1 pA at 25°C, with the same common-mode input range as the other channels. |
| 6 | 2IN- | input | Inverting input of amplifier 2; input bias current is typically 1 pA at 25°C, with the same common-mode input range as the other channels. |
| 7 | 2OUT | output | Output of amplifier 2, rail-to-rail; output swing is specified as tens of mV from the supply rails, and short-circuit source/sink current is listed as IOS. |
| 8 | 3OUT | output | Output of amplifier 3, rail-to-rail; output swing is specified as tens of mV from the supply rails, and short-circuit source/sink current is listed as IOS. |
| 9 | 3IN- | input | Inverting input of amplifier 3; input bias current is typically 1 pA at 25°C, with the same common-mode input range as the other channels. |
| 10 | 3IN+ | input | Non-inverting input of amplifier 3; input bias current is typically 1 pA at 25°C, with the same common-mode input range as the other channels. |
| 11 | GND | power_in | Ground / negative supply reference (0 V) for the single-supply operation; the datasheet defines all voltages relative to this GND pin. |
| 12 | 4IN+ | input | Non-inverting input of amplifier 4; input bias current is typically 1 pA at 25°C, with the same common-mode input range as the other channels. |
| 13 | 4IN- | input | Inverting input of amplifier 4; input bias current is typically 1 pA at 25°C, with the same common-mode input range as the other channels. |
| 14 | 4OUT | output | Output of amplifier 4, rail-to-rail; output swing is specified as tens of mV from the supply rails, and short-circuit source/sink current is listed as IOS. |
