LT1019ACS8-2.5#PBF
Analog Devices · Voltage References · SOIC-8
LT1019ACS8-2.5#PBF from Analog Devices, in a SOIC-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 | DNC | unconnected | Internally connected; do not connect externally. |
| 2 | INPUT | power_in | Input supply voltage, absolute maximum 40V, with minimum input/output differential of about 0.9V to 1.1V at IOUT ≤ 1mA. |
| 3 | TEMP | output | Temperature output voltage proportional to absolute temperature (about 2.1mV/°C, roughly 620mV at room temperature), with absolute maximum pin voltage of 5V. |
| 4 | GND | power_in | Ground connection of the reference. |
| 5 | TRIM | passive | Output voltage trim pin, absolute maximum ±30V, used with a potentiometer from output to ground (trim range e.g. +6%/-6% for LT1019-2.5). |
| 6 | OUTPUT | power_out | Reference output that can source and sink up to 10mA; LT1019-2.5 output absolute maximum is 7V. |
| 7 | DNC | unconnected | Internally connected; do not connect externally. |
| 8 | DNC | unconnected | Internally connected; do not connect externally. |
