# THS4541IRGTR

**Texas Instruments** · Differential OpAmps · VQFN-16-EP(3x3)

THS4541IRGTR 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 | FB- | output | Feedback connection pin for negative output signal path in closed-loop configuration. |
| 2 | IN+ | input | In-phase (positive) amplifier input for differential signal reception. |
| 3 | IN- | input | Inverse (negative) amplifier input for differential signal reception. |
| 4 | FB+ | output | Feedback connection pin for positive output signal path in closed-loop configuration. |
| 5 | Vs+ | power_in | Positive power supply input, 2.7V to 5.4V. |
| 6 | Vs+ | power_in | Positive power supply input, 2.7V to 5.4V. |
| 7 | Vs+ | power_in | Positive power supply input, 2.7V to 5.4V. |
| 8 | Vs+ | power_in | Positive power supply input, 2.7V to 5.4V. |
| 9 | Vocm | input | Common mode voltage input to set output average voltage; defaults to 1/2 Vs when left open circuit. |
| 10 | OUT+ | output | In-phase (positive) amplifier output with rail-to-rail swing and 0.2V minimum margin from supply rails. |
| 11 | OUT- | output | Inverse (negative) amplifier output with rail-to-rail swing and 0.2V minimum margin from supply rails. |
| 12 | PD | input | Power-down control; logic high enables normal operation, logic low (within 0.7V of Vs-) disables device with typical 2µA quiescent current. |
| 13 | Vs- | power_in | Negative power supply input (ground reference). |
| 14 | Vs- | power_in | Negative power supply input (ground reference). |
| 15 | Vs- | power_in | Negative power supply input (ground reference). |
| 16 | Vs- | power_in | Negative power supply input (ground reference). |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
