LTC6930HDCB-4.19#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6930HDCB-4.19#TRMPBF is a precision micro-power silicon oscillator from Analog Devices, operating within a –40°C to 125°C temperature range. It features a factory-set master frequency of 4.194304MHz with an initial accuracy of less than 0.09% at 25°C. The device supports eight selectable output frequencies ranging from 32.768kHz to 8.192MHz via internal dividers controlled by DIVA, DIVB, and DIVC pins. Supply current ranges from 80µA to 490µA depending on voltage and frequency settings. It operates on a single 1.7V to 5.5V supply and utilizes an 8-lead (2mm × 3mm) plastic DFN package.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging containing 500 pieces. Confirm the 'H' grade designation corresponds to the –40°C to 125°C extended temperature range. Ensure compatibility with the 8-lead DFN footprint during procurement planning.

Programmable Timers And Oscillators Selection Notes

Select this part for applications requiring high precision with minimal external components. The H-grade variant is necessary for environments exceeding 85°C. Verify that the required output frequency matches one of the eight divisions of the 4.194304MHz master oscillator available in Table 1 of the datasheet.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6930 family of precision µPower Oscillators. The DCB suffix identifies the 8-lead (2mm × 3mm) Plastic DFN package. The -4.19 suffix denotes the specific master oscillator frequency of 4.194304MHz, which divides down to provide standard timing frequencies.

Programmable Timers And Oscillators Replacement Considerations

LTC6930IDCB-4.19#TRMPBF offers identical electrical performance but is rated for a commercial temperature range of –40°C to 85°C.
