Maxim Integrated · Voltage References · MSOP-8
MAX6126A28+ from Maxim Integrated, in a MSOP-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 | NR | passive | Noise reduction pin: connect a 0.1µF capacitor to improve wideband noise (60nV/√Hz to 35nV/√Hz for 2.048V output), or leave unconnected if not used. |
| 2 | IN | power_in | Positive power-supply input, operating from (VOUT + 200mV) to 12.6V with an absolute maximum of -0.3V to +13V relative to GND. |
| 3 | GND | power_in | Ground. |
| 4 | GNDS | input | Ground-sense connection, to be connected to the ground connection at the load (limited to -0.3V to +0.3V relative to GND). |
| 5 | I.C. | unconnected | Internally connected; do not connect anything to this pin. |
| 6 | OUTS | input | Voltage reference sense output, brought to the point where voltage accuracy is needed and joined to OUTF as close to the load as possible. |
| 7 | OUTF | output | Voltage reference force output supplying load current (10mA sink/source); short to OUTS as close to the load as possible and bypass with a 0.1µF to 10µF capacitor to GND. |
| 8 | I.C. | unconnected | Internally connected; do not connect anything to this pin. |
