MAX6250BESA+T from Analog Devices Inc Maxim Integrated, in a SO-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; the datasheet says do not use this pin. |
| 2 | IN | power_in | Positive power-supply input, specified at 8V to 36V, with an absolute maximum of -0.3V to +40V referenced to GND. |
| 3 | NR | passive | Noise-reduction pin for an optional 1µF capacitor to add wideband noise reduction; leave open if not used, and the absolute maximum range is -0.3V to +6V. |
| 4 | GND | power_in | Ground reference for the reference and all voltage limits in the datasheet. |
| 5 | TRIM | input | External trim input that allows output adjustment (stated as ±1% in the pin table) via a 10kΩ potentiometer between OUT and GND; leave open if not used, and the absolute maximum range is -0.3V to +12V. |
| 6 | OUT | power_out | Voltage reference output (5.000V for the MAX6250); absolute maximum range is -0.3V to +12V, and it is continuously short-circuit-protected to GND for VIN ≤ 12V. |
| 7 | I.C. | unconnected | Internally connected; the datasheet says do not use this pin. |
| 8 | I.C. | unconnected | Internally connected; the datasheet says do not use this pin. |
