THS4511RGTT

Texas Instruments · Low Noise Amplifiers (LNA) - RF · VQFN-16-EP(3x3)

THS4511RGTT from Texas Instruments, in a VQFN-16-EP(3x3). 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 NC unconnected No internal connection.
2 VIN- power_in Inverting amplifier input.
3 VOUT+ output Noninverting amplifier output; an output resistor is recommended close to the pin.
4 CM input Common-mode voltage input; set to midsupply internally, can be overdriven externally, and a 0.1-µF capacitor to ground is recommended near this pin.
5 VS+ power_in Positive amplifier power supply input.
6 VS+ power_in Positive amplifier power supply input.
7 VS+ power_in Positive amplifier power supply input.
8 VS+ power_in Positive amplifier power supply input.
9 CM input Common-mode voltage input; set to midsupply internally, can be overdriven externally, and a 0.1-µF capacitor to ground is recommended near this pin.
10 VOUT- output Inverted amplifier output; an output resistor is recommended close to the pin.
11 VIN+ power_in Noninverting amplifier input.
12 PD input Power-down; logic low puts part into low power mode, logic high or open for normal operation.
13 VS- power_in Negative amplifier power-supply input.
14 VS- power_in Negative amplifier power-supply input.
15 VS- power_in Negative amplifier power-supply input.
16 VS- power_in Negative amplifier power-supply input.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
