LT1027CCS8-5#TRPBF
Analog Devices · Voltage Reference · SO-8
LT1027CCS8-5#TRPBF 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 | VIN | power_in | Supply input; the supply voltage (VIN) absolute maximum is 40V and the input-output differential is limited to 35V. |
| 2 | NC | unconnected | Connected internally; do not connect external circuitry to this pin. |
| 3 | NC | unconnected | Connected internally; do not connect external circuitry to this pin. |
| 4 | NC | unconnected | Connected internally; do not connect external circuitry to this pin. |
| 5 | VOUT | power_out | 5V reference output that sources up to 15mA and sinks up to 10mA; output-to-ground voltage is limited to 7V, and short-circuit duration is 10 sec when VIN > 20V or indefinite when VIN ≤ 20V. |
| 6 | VTRIM | input | Output voltage trim pin (about 20kΩ impedance, 2.5V open-circuit); VTRIM-to-ground is limited to +5V positive and -0.3V negative, with a ±30mV guaranteed trim range. |
| 7 | GND | power_in | Ground return; the ground pin carries only 2mA and can be used as a low-side Kelvin sense line. |
| 8 | NR | passive | Noise reduction pin (positive input of the internal scaling amplifier) for a 1µF low-leakage Mylar capacitor to ground; it is the most sensitive pin, and 100nA of leakage causes a 150ppm output error. |
