LTC1799HS5#WTRMPBF

Programmable Timers And Oscillators Overview

The LTC1799HS5#WTRMPBF 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 frequency programming and features a three-state DIV input for division 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 temperature grade ranging from -40°C to 125°C, packaged in a low-profile 5-lead TSOT-23.

Programmable Timers And Oscillators Feature Summary

• Frequency Range: 1kHz to 33MHz via RSET and DIV pin settings
• High Accuracy: Frequency error ≤1.5% at 25°C for 5kHz to 20MHz
• Temperature Stability: ±40ppm/°C drift over the full operating range
• Automotive Grade: AEC-Q100 qualified with #W suffix manufacturing controls

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 automotive qualification status by confirming the presence of the '#W' suffix in the part number, which denotes controlled manufacturing for AEC-Q100 reliability requirements. Ensure the 'HS5' designation matches the required -40°C to 125°C operating temperature range for the specific application environment.

Programmable Timers And Oscillators Selection Notes

Select this component when a low-cost, high-precision oscillator is needed without external trim components. The LTC1799HS5#WTRMPBF is suitable for designs requiring operation up to 125°C junction temperature. Consider the master oscillator frequency limits; accuracy may degrade if the master frequency exceeds 10MHz with a supply voltage below 4V.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC1799 TimerBlox family of resistor-set oscillators. The HS5 variant specifically designates the extended temperature range (-40°C to 125°C) compared to the IS5 variant (-40°C to 85°C). The #W suffix indicates compliance with automotive quality standards, distinguishing it from standard commercial versions.

Programmable Timers And Oscillators Replacement Considerations

LTC1799IS5#WTRMPBF offers identical electrical performance but with a limited operating temperature range of -40°C to 85°C.
