The 6-DFN (2x3 mm) package with exposed pad aids thermal transfer to the PCB ground plane. ## Active production and compliance The TimerBlox® series remains a current product line from Analog Devices, with no pin-compatible successor announced. ## Supply current and voltage range for system integration At 235 µA supply current, the LTC6990 draws less than a typical crystal oscillator plus buffer chain — relevant for battery-powered instrumentation or sensor nodes where every microamp is budgeted. The output frequency is set by a single resistor between the SET pin and ground, with the formula given in the datasheet. ## Package and thermal considerations for PCB layout Surface-mount assembly with Tape & Reel packaging supports automated pick-and-place. The exposed pad must be soldered to the PCB ground plane to achieve the rated thermal performance; a floating pad raises junction temperature under continuous operation.","metaTitle":"LTC6990HDCB#TRMPBF Silicon Oscillator, 488Hz-1MHz, TimerBlox","metaDescription":"Analog Devices LTC6990HDCB#TRMPBF silicon oscillator, 488Hz to 1MHz, 235µA supply, 2.25-5.5V, -40 to 125°C, 6-DFN.
