Product details

Programmable silicon oscillator for timing generation

The LTC6990IS6#TRMPBF is a silicon oscillator from Analog Devices' TimerBlox® series, covering 488 Hz to 1 MHz with a single resistor programming. It runs on a 2.25V to 5.5V supply and draws 235 µA typical, making it a fit for battery-powered or low-power timing chains where a quartz crystal is overkill or physically too large.

Supply voltage and frequency range

The 2.25V to 5.5V supply range matches 3.3V and 5V rails common in industrial control and sensor interfaces. The 488 Hz to 1 MHz programmable range covers most low-to-mid frequency timing needs — think watchdog clocks, PWM base rates, or simple square-wave generation — without needing an external crystal or ceramic resonator.

The TSOT-23-6 package (SOT-23-6 Thin, TSOT-23-6) is a compact surface-mount footprint that fits tight layouts without a dedicated oscillator footprint.

Active lifecycle and sourcing posture

It is ROHS3 compliant. Sourced per RFQ against your BOM quantity; current pricing and lead time confirmed at quote time.

Frequently asked questions

Can LTC6990IS6#TRMPBF replace other LTC6990 variants?

The LTC6990IS6#TRMPBF is the industrial-temperature-range variant (-40°C to 85°C) in a TSOT-23-6 package. The sibling LTC6990HDCB#TRMPBF extends the temperature range to 125°C but uses a different package (DFN). Check the package and temperature grade against your BOM before substituting.

How do I program the frequency of LTC6990IS6#TRMPBF?

Frequency is set by a single external resistor between the SET pin and ground. The datasheet provides the resistor value formula for the desired output frequency within the 488 Hz to 1 MHz range.
