# LTC8554XS14

**Linearin** · Precision OpAmps · SOIC-14L

LTC8554XS14 from Linearin, in a SOIC-14L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output. Rail-to-rail output stage; short-circuit current ~40 mA source / 50 mA sink through 10 Ω. |
| 2 | -INA | input | Inverting input of amplifier A. Rail-to-rail input; common-mode range Vs- - 0.1 V to Vs+ + 0.1 V. |
| 3 | +INA | input | Non-inverting input of amplifier A. Rail-to-rail input; common-mode range Vs- - 0.1 V to Vs+ + 0.1 V. |
| 4 | +Vs | power_in | Positive (highest) power supply. Operating range 1.8 V to 5.5 V (2.0 V to 5.5 V over full -40 to +125 °C); absolute maximum Vs+ to Vs- = 10.0 V. |
| 5 | +INB | input | Non-inverting input of amplifier B. Rail-to-rail input. |
| 6 | -INB | input | Inverting input of amplifier B. Rail-to-rail input. |
| 7 | OUTB | output | Amplifier B output. Rail-to-rail output stage. |
| 8 | OUTC | output | Amplifier C output. Rail-to-rail output stage. |
| 9 | -INC | input | Inverting input of amplifier C. Rail-to-rail input. |
| 10 | +INC | input | Non-inverting input of amplifier C. Rail-to-rail input. |
| 11 | -Vs | power_in | Negative (lowest) power supply. Typically tied to GND for single-supply operation; supplies below Vs- (or above +Vs by more than 10 V total) can permanently damage the device. |
| 12 | +IND | input | Non-inverting input of amplifier D. Rail-to-rail input. |
| 13 | -IND | input | Inverting input of amplifier D. Rail-to-rail input. |
| 14 | OUTD | output | Amplifier D output. Rail-to-rail output stage. |
