Programmable silicon oscillator in a TSOT-23-6 package
The LTC6907HS6#TRMPBF is a programmable silicon oscillator from Analog Devices that generates a square-wave output from 40 kHz to 4 MHz, set by a single external resistor. It operates from a 3 V to 3.6 V supply and draws only 305 µA typical supply current, making it a low-power alternative to ceramic resonators or RC oscillators in timing applications. The 'H' suffix denotes the extended industrial temperature range of -40°C to 125°C, suitable for environments where standard commercial oscillators would drift or fail.
Frequency set by one resistor — no external capacitor needed
Output frequency is programmed by a single resistor (RSET) between the SET pin and ground, with no capacitor required. The resistor value determines the frequency according to a simple formula in the datasheet. This eliminates the need for a timing capacitor and reduces BOM count and board area. The frequency range of 40 kHz to 4 MHz covers many common microcontroller clock, DC-DC converter synchronisation, and sensor excitation needs.
305 µA supply current — a fit for battery-operated designs
At 305 µA typical supply current, the LTC6907HS6 draws significantly less than a typical crystal oscillator module (often 1 mA to 5 mA). This makes it a strong candidate for portable, battery-powered, or energy-harvesting equipment where every microamp matters. The low current also reduces self-heating in the TSOT-23-6 package, keeping the junction temperature well within the -40°C to 125°C operating range even in warm enclosures.
Active lifecycle — no end-of-life concern for new designs
It is also ROHS3 compliant.
