THS4303RGTT

Texas Instruments · Operational Amplifier · VQFN-16-EP(3x3)

THS4303RGTT 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 VS- power_in Negative supply pin (one of four VS- pins, 1-4); dual supply ±1.5 V to ±2.5 V, or ground for single 3 V to 5 V supply.
2 VS- power_in Negative supply pin (one of four VS- pins, 1-4); dual supply ±1.5 V to ±2.5 V, or ground for single 3 V to 5 V supply.
3 VS- power_in Negative supply pin (one of four VS- pins, 1-4); dual supply ±1.5 V to ±2.5 V, or ground for single 3 V to 5 V supply.
4 VS- power_in Negative supply pin (one of four VS- pins, 1-4); dual supply ±1.5 V to ±2.5 V, or ground for single 3 V to 5 V supply.
5 VOUT output Amplifier output (one of four VOUT pins, 5-8) for the fixed gain of +10 V/V, with output current up to ±180 mA.
6 VOUT output Amplifier output (one of four VOUT pins, 5-8) for the fixed gain of +10 V/V, with output current up to ±180 mA.
7 VOUT output Amplifier output (one of four VOUT pins, 5-8) for the fixed gain of +10 V/V, with output current up to ±180 mA.
8 VOUT output Amplifier output (one of four VOUT pins, 5-8) for the fixed gain of +10 V/V, with output current up to ±180 mA.
9 VS+ power_in Positive supply pin (one of four VS+ pins, 9-12); dual supply ±1.5 V to ±2.5 V or single 3 V to 5 V, absolute maximum 6 V.
10 VS+ power_in Positive supply pin (one of four VS+ pins, 9-12); dual supply ±1.5 V to ±2.5 V or single 3 V to 5 V, absolute maximum 6 V.
11 VS+ power_in Positive supply pin (one of four VS+ pins, 9-12); dual supply ±1.5 V to ±2.5 V or single 3 V to 5 V, absolute maximum 6 V.
12 VS+ power_in Positive supply pin (one of four VS+ pins, 9-12); dual supply ±1.5 V to ±2.5 V or single 3 V to 5 V, absolute maximum 6 V.
13 NC unconnected No connect.
14 VIN- power_in Inverting input, which is the ground end of the internal 50 Ω Rg gain-setting resistor, and should have a very low inductance path to ground.
15 VIN+ power_in Noninverting input with 1.6 MΩ
16 PD input Power-down input, active low, defaulting to the positive supply (power on); above 1.5 V the device is on, below 0.9 V it is off.
17 EP passive Exposed thermal pad (PowerPAD) that must be soldered to a thermally dissipative copper plane for power dissipation.
