WS72324Q-16 from WILLSEMI Will Semicon, in a QFN3x3-16. 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 | +INA | input | Non-inverting input of Amplifier A. High-impedance analog input; common-mode range (V-)-0.2 V to (V+)+0.2 V (rail-to-rail input). |
| 2 | V+ | power_in | Positive supply rail. Operating range 1.8-5.5 V; absolute maximum V+ - V- = 6 V. Bypass with a local 0.1 uF ceramic capacitor to V-. |
| 3 | NC | unconnected | No internal connection. Leave floating or tie to a stable potential; do not use as a signal tie point. |
| 4 | +INB | input | Non-inverting input of Amplifier B. Rail-to-rail high-impedance analog input. |
| 5 | -INB | input | Inverting input of Amplifier B. High-impedance analog input; use for feedback network summing node. |
| 6 | OUTB | output | Output of Amplifier B. Rail-to-rail output; typical short-circuit source current 43 mA, sink 47 mA. Stable for any Cload with appropriate feedback. |
| 7 | OUTC | output | Output of Amplifier C. Rail-to-rail output; typical short-circuit source current 43 mA, sink 47 mA. |
| 8 | -INC | input | Inverting input of Amplifier C. High-impedance analog input. |
| 9 | +INC | input | Non-inverting input of Amplifier C. Rail-to-rail high-impedance analog input. |
| 10 | NC | unconnected | No internal connection. Leave floating or tie to a stable potential. |
| 11 | V- | power_in | Negative supply rail (or ground for single-supply operation). Absolute maximum V+ - V- = 6 V. |
| 12 | +IND | input | Non-inverting input of Amplifier D. Rail-to-rail high-impedance analog input. |
| 13 | -IND | input | Inverting input of Amplifier D. High-impedance analog input. |
| 14 | OUTD | output | Output of Amplifier D. Rail-to-rail output; typical short-circuit source current 43 mA, sink 47 mA. |
| 15 | OUTA | output | Output of Amplifier A. Rail-to-rail output; typical short-circuit source current 43 mA, sink 47 mA. Pin number inferred from QFN3x3-16L package outline (pins N1..N16) and the top-view pin configuration diagram, as the pin-description table for the Q-16 variant on page 2 omits OUTA/-INA rows. |
| 16 | -INA | input | Inverting input of Amplifier A. High-impedance analog input. Pin number inferred from the QFN3x3-16L top-view pin configuration diagram; the Q-16 pin table on page 2 omits this row. |
