LT6654AMPS6-3.3#TRMPBF

Analog Devices · Voltage References · TSOT-23-6L

LT6654AMPS6-3.3#TRMPBF from Analog Devices, in a TSOT-23-6L. 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.
2 GND power_in Primary device ground; Pin 1 must be tied to this pin and the load ground should be star-connected to it.
3 DNC unconnected Do not connect; keep leakage current from this pin to VIN or GND to a minimum. Connected internally, so no external circuitry should be applied.
4 VIN power_in Power supply input; bypass with a 0.1µF capacitor to ground. Operating supply range is (VOUT + 0.5V) < VIN < 36V, with absolute maximum VIN of 38V.
5 DNC unconnected Do not connect; keep leakage current from this pin to VIN or GND to a minimum. Connected internally, so no external circuitry should be applied.
6 VOUT power_out Buffered voltage reference output; an output capacitor of 1µF minimum is required for stable operation and the part sources or sinks ±10mA.
