THS6222IRHFR from Texas Instruments, in a VQFN-24-EP(4x5). 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 | D1_IN+ | input | Amplifier D1 noninverting input; common-mode input voltage ±3.0V with respect to midsupply at VS = 12V |
| 2 | D2_IN+ | input | Amplifier D2 noninverting input; common-mode input voltage ±3.0V with respect to midsupply at VS = 12V |
| 3 | DGND | power_in | Ground reference for bias control pins; voltage must range from VS- to (VS+) - 5V per specification |
| 4 | IADJ | input | Bias current adjustment pin; external resistor to ground adjusts quiescent current across full-bias to shutdown modes |
| 5 | VCM | output | Common-mode buffer output providing integrated 1/2 Vs voltage reference; typical offset ±2.5mV for AC-coupled input applications |
| 6 | NC | unconnected | No internal connection |
| 7 | NC | unconnected | No internal connection |
| 8 | NC | unconnected | No internal connection |
| 9 | NC | unconnected | No internal connection |
| 10 | NC | unconnected | No internal connection |
| 11 | NC | unconnected | No internal connection |
| 12 | NC | unconnected | No internal connection |
| 13 | NC | unconnected | No internal connection |
| 14 | NC | unconnected | No internal connection |
| 15 | NC | unconnected | No internal connection |
| 16 | NC | unconnected | No internal connection |
| 17 | D2_OUT | output | Amplifier D2 output; differential transmission line driver pair with D1_OUT, supplies ±338mA into 25Ω load at VS = 12V |
| 18 | D2_IN- | input | Amplifier D2 inverting input; part of D2 differential input pair referenced to DGND |
| 19 | D1_IN- | input | Amplifier D1 inverting input; part of D1 differential input pair referenced to DGND |
| 20 | D1_OUT | output | Amplifier D1 output; differential transmission line driver pair with D2_OUT, supplies ±338mA into 25Ω load at VS = 12V |
| 21 | VS+ | power_in | Positive power-supply connection; operating range 8V to 32V for single-supply or split-supply operation |
| 22 | VS- | power_in | Negative power-supply connection; ground return for single-supply or negative rail for split-supply (−3V to −27V from reference) |
| 23 | BIAS-1 | input | Bias mode control LSB; logic level relative to DGND (0.8V for logic 0, 2.1V for logic 1) selects operating mode; floating input causes shutdown |
| 24 | BIAS-2 | input | Bias mode control MSB; logic level relative to DGND (0.8V for logic 0, 2.1V for logic 1) selects operating mode; floating input causes shutdown |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
