LTC1799HS5#TRMPBF

Programmable Timers And Oscillators Overview

The LTC1799HS5#TRMPBF is a precision silicon oscillator from Analog Devices, operating within a frequency range of 1kHz to 33MHz. It utilizes a single external resistor (RSET) for programming and features a three-state DIV input for dividing the master clock by 1, 10, or 100. The device operates on a single 2.7V to 5.5V supply with a typical current consumption of 1mA. It provides a rail-to-rail CMOS output with fast rise/fall times. The HS5 suffix indicates an industrial/high-temperature grade rated for -40°C to 125°C, housed in a low-profile 5-lead TSOT-23 package.

Programmable Timers And Oscillators Feature Summary

• Frequency Range: 1kHz to 33MHz via RSET and DIV pin settings
• High Accuracy: ≤1.5% frequency error at 25°C; ±40ppm/°C temperature stability
• Low Power: 1mA typical supply current; <1ms start-up time
• Automotive Qualified: AEC-Q100 compliant for high reliability applications

Programmable Timers And Oscillators Applications

• Switching power supply clock reference
• Fixed crystal oscillator replacement
• Clocking switched capacitor filters
• Ceramic oscillator replacement

Programmable Timers And Oscillators Procurement Notes

Verify the HS5 suffix confirms the -40°C to 125°C operating range. Confirm the #TRMPBF suffix corresponds to the 500-unit mini tape and reel packaging. Ensure the component meets AEC-Q100 requirements if used in automotive contexts.

Programmable Timers And Oscillators Selection Notes

Select this variant for applications requiring extended temperature operation up to 125°C. Use the DIV pin to adjust frequency ranges: GND for ÷1, floating for ÷10, and V+ for ÷100. Ensure RSET values remain between 3kΩ and 1MΩ for optimal performance.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC1799 family of resistor-set silicon oscillators. The HS5 designation specifically denotes the high-temperature industrial grade (-40°C to 125°C), distinguishing it from the IS5 (industrial, -40°C to 85°C) and CS5 (commercial, 0°C to 70°C) variants.

Programmable Timers And Oscillators Replacement Considerations

Public confirmed substitutes include LTC1799IS5#TRMPBF for lower temperature requirements and LTC1799CS5#TRMPBF for commercial grades. All share identical pinouts and electrical functions but differ in operating temperature ranges.
