MAX923CSA+ from Maxim Integrated, in a SOIC-8. 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 | OUTA | output | Comparator A output that sinks and sources current and swings from V+ to V-. |
| 2 | V- | power_in | Negative supply; connect to ground for single-supply operation. |
| 3 | INA+ | input | Noninverting input of comparator A, with input range from V- to V+ - 1.3V guaranteed. |
| 4 | INB- | input | Inverting input of comparator B, with input range from V- to V+ - 1.3V guaranteed. |
| 5 | HYST | input | Hysteresis input; connect to REF if not used, with input voltage range from VREF to VREF - 50mV. |
| 6 | REF | output | Reference output of 1.182V with respect to V-; do not bypass. |
| 7 | V+ | power_in | Positive supply, +2.5V to +11V. |
| 8 | OUTB | output | Comparator B output that sinks and sources current and swings from V+ to V-. |
