LT1461CCS8-4#PBF

Analog Devices · Voltage References · SO-8

LT1461CCS8-4#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 DNC unconnected Do Not Connect: the datasheet marks this pin DNC and it must be left unconnected.
2 VIN power_in Supply input; the datasheet requires (VOUT + 0.3V) ≤ VIN ≤ 20V, with an absolute maximum of 20V.
3 SHDN input Active-low shutdown input: pulling below 0.8V (max logic low) shuts off load current, while leaving it open or driving it to at least 2.4V (min logic high) keeps the reference operating normally.
4 GND power_in Ground reference for the reference and the output short-circuit condition (VOUT shorted to GND).
5 DNC unconnected Do Not Connect: the datasheet marks this pin DNC and it must be left unconnected.
6 VOUT power_out Reference output, rated for 50mA minimum sourcing with 100mA short-circuit current limit and indefinite short-circuit duration; use a 1µF capacitor for loads ≤1mA and 2µF or greater for loads up to 75mA.
7 DNC unconnected Do Not Connect: the datasheet marks this pin DNC and it must be left unconnected.
8 DNC unconnected Do Not Connect: the datasheet marks this pin DNC and it must be left unconnected.
