# MAX6241BCSA+

**Maxim Integrated** · Voltage References · SOIC-8

MAX6241BCSA+ 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 | I.C. | unconnected | Internally connected pin that must not be used. |
| 2 | IN | power_in | Positive power-supply input, specified for 8V to 36V input voltage range. |
| 3 | NR | passive | Optional noise-reduction capacitor connection; a 1µF capacitor to GND is added for wideband noise reduction, and the pin is left open if not used. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | TRIM | input | External trim input allowing ±1% output adjustment (minimum 0.6% per the trim description); left open if not used. |
| 6 | OUT | power_out | Voltage reference output, 4.096V for the MAX6241, sourcing and sinking up to ±15mA. |
| 7 | I.C. | unconnected | Internally connected pin that must not be used. |
| 8 | I.C. | unconnected | Internally connected pin that must not be used. |
