1XXB26000MSA from KDS Daishinku, in a SMD2520-4P. 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 | GND | power_in | Ground terminal; the datasheet's pin connection table lists #1 as GND with no further electrical limits. |
| 2 | GND | power_in | Ground terminal; the datasheet's pin connection table lists #2 as GND with no further electrical limits. |
| 3 | Output | output | Clipped sine wave output (DC-coupled) with a minimum output level of 0.8 VP-P, specified with load 5 kΩ // 40 pF. |
| 4 | VCC | power_in | Supply voltage input; recommended range is +1.71 V to +2.94 V (typical 1.8, 2.2 or 2.8 V), with an absolute maximum of -0.3 V to +4.6 V. |
