LT6654AIS6-5#TRMPBF

Analog Devices · Voltage References · TSOT-23-6

LT6654AIS6-5#TRMPBF from Analog Devices, in a TSOT-23-6. 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 GND power_in Internal function pin that must be tied to ground, near Pin 2 (the datasheet's pin 1 is connected to device GND, and the pin configuration marks it with an asterisk to connect to pin 2).
2 GND power_in Primary device ground.
3 DNC unconnected Do not connect; keep leakage current from this pin to VIN or GND to a minimum, and do not connect external circuitry to it.
4 VIN power_in Power supply input; bypass VIN with a 0.1µF capacitor to ground (the device is specified for supply voltages up to 36V).
5 DNC unconnected Do not connect; keep leakage current from this pin to VIN or GND to a minimum, and do not connect external circuitry to it.
6 VOUT power_out Buffered voltage reference output; an output capacitor of 1µF minimum is required for stable operation.
