**CIMO** · Precision Op Amps · SOT-23-5

CM4141-SOTTA from CIMO, in a SOT-23-5. 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 | OUT | output | Amplifier output with rail-to-rail swing, limited to (V-) - 0.3 V to (V+) + 0.3 V, with short-circuit current limit of about 21 mA to V- and -35 mA to V+ at 5 V. |
| 2 | V- | power_in | Negative supply, ground in single-supply operation; analog inputs and output must stay within (V-) - 0.3 V. |
| 3 | +IN | input | Non-inverting input with rail-to-rail input range of 0 V to VS and input bias current of 100 pA maximum at 25 °C. |
| 4 | -IN | input | Inverting input with rail-to-rail input range of 0 V to VS and input bias current of 100 pA maximum at 25 °C. |
| 5 | V+ | power_in | Positive supply, 2.7 V to 5 V operating with absolute maximum supply voltage of 6 V. |
