LTC1050CS8#PBF from Analog Devices, 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 | NC | unconnected | Not connected internally. |
| 2 | -IN | input | Inverting input of the zero-drift op amp. |
| 3 | +IN | input | Non-inverting input; common mode range includes ground (V- to 2.7V CMRR test range at VS = ±5V). |
| 4 | V- | power_in | Negative supply (total supply V+ to V- limited to 18V absolute maximum; ground in single-supply use). |
| 5 | EXT CLOCK INPUT | bidirectional | Optional external clock input (internal oscillator output through 2k, 4x the sampling frequency of about 2.5kHz); leave floating when unused and avoid capacitive loading. |
| 6 | OUT | output | Amplifier output, swings to ground, with indefinite short-circuit duration. |
| 7 | V+ | power_in | Positive supply (single-supply operation 4.75V to 16V total). |
| 8 | NC | unconnected | Not connected internally. |
