LMV344IPWRQ1

Texas Instruments · Operational Amplifier · TSSOP-14

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.
