WS72324Q-16

WILLSEMI Will Semicon · Operational Amplifier · QFN3x3-16

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.
