THS4561IRGTR

Texas Instruments · Differential Amplifiers · VQFN-16(3x3)

THS4561IRGTR from Texas Instruments, in a VQFN-16(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 FB- output Inverting output feedback connection for setting closed-loop gain and loop compensation in fully differential feedback topology.
2 IN+ input Noninverting (positive) differential amplifier input accepting common-mode voltage from VS− − 0.1 V to VS+ − 1.2 V.
3 IN- input Inverting (negative) differential amplifier input accepting common-mode voltage from VS− − 0.1 V to VS+ − 1.2 V.
4 FB+ output Noninverting output feedback connection for setting closed-loop gain and loop compensation in fully differential feedback topology.
5 VS+ power_in Positive power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−.
6 VS+ power_in Positive power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−.
7 VS+ power_in Positive power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−.
8 VS+ power_in Positive power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−.
9 VOCM input Output common-mode voltage control input setting differential output average voltage from VS− + 0.45 V to VS+ − 1.2 V; defaults to midsupply when floated.
10 OUT+ output Noninverting (positive) differential amplifier output with rail-to-rail swing capability requiring ≈200 mV headroom; continuous output current ±20 mA.
11 OUT- output Inverting (negative) differential amplifier output with rail-to-rail swing capability requiring ≈200 mV headroom; continuous output current ±20 mA.
12 PD input Power-down control input; threshold high >VS+ − 0.5 V enables normal operation, threshold low <VS+ − 1.8 V disables amplifier reducing quiescent current to 3−40 µA.
13 VS- power_in Negative power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−.
14 VS- power_in Negative power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−.
15 VS- power_in Negative power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−.
16 VS- power_in Negative power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
