What this silicon oscillator brings to the board
The LTC6906HS6#TRMPBF is a silicon oscillator from Analog Devices that generates a square-wave output from 10 kHz to 1 MHz, set by a single external resistor. It draws only 78 µA typical supply current, making it a fit for battery-powered or power-sensitive timing chains where a quartz crystal would be overkill or too bulky. The TSOT-23-6 package (SOT-23-6 Thin) keeps the footprint small, which helps on dense boards where every square millimeter counts.
Operating from 2.25 V to 3.6 V, the LTC6906HS6#TRMPBF runs directly off a 3.3 V or 2.5 V rail without a separate LDO. The 78 µA supply current is the total chip draw — no external bias resistors or bypass caps add to the tally, so the BOM current budget stays tight.
Lifecycle and sourcing — active production, no end-of-life concern
It is ROHS3 compliant and ships in Tape & Reel (TR) or Cut Tape (CT) options.
Package and assembly — TSOT-23-6 considerations
The TSOT-23-6 package is a thin SOT-23 variant with 0.95 mm pitch and a 2.9 mm × 1.6 mm body. It is a standard footprint that most pick-and-place machines handle without special nozzles. The part is surface-mount only. Check the MSL rating on the reel label before reflow — if it is MSL 1, no bake needed; if MSL 2 or higher, a pre-bake at 125°C for the specified duration prevents popcorning.
