LTC1799CS5#TRPBF

Programmable Timers And Oscillators Overview

The LTC1799CS5#TRPBF is a precision silicon oscillator from Analog Devices Inc., housed in a 5-lead TSOT-23 package. It operates on a single 2.7V to 5.5V supply with a typical current of 1mA. The frequency range spans 1kHz to 33MHz, determined by a single external resistor (RSET) and a three-state DIV input for division ratios of 1, 10, or 100. Frequency accuracy is ±1.5% at 25°C for the 5kHz to 20MHz range. The device provides a rail-to-rail CMOS output with fast rise/fall times and low jitter.

Programmable Timers And Oscillators Feature Summary

• Frequency set by a single external resistor with proprietary linearization feedback loop
• Three-state DIV input allows division by 1, 10, or 100 for extended frequency ranges
• Rail-to-rail CMOS output driver with 100Ω impedance
• Low profile 1mm TSOT-23 package suitable for space-constrained designs

Programmable Timers And Oscillators Applications

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

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRPBF indicates standard tape and reel packaging. Confirm the 'C' grade designation matches the required 0°C to 70°C operating temperature range for the target application environment. Ensure compatibility with the 5-lead TSOT-23 footprint during PCB layout.

Programmable Timers And Oscillators Selection Notes

Select this component when a low-cost, small-footprint oscillator is needed without external trimming. Choose based on the required frequency range and divider setting to optimize RSET values for best accuracy. Consider the ±40ppm/°C temperature stability if operating outside ambient conditions.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC1799 family of resistor-set oscillators. The 'C' suffix denotes the commercial temperature grade (0°C to 70°C), while 'I' and 'H' grades offer wider industrial and high-temperature ranges. The '#TRPBF' suffix specifies the lead-free tape and reel packaging format.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-compatible replacements within the same package include the LTC1799IS5#TRPBF for industrial temperature range (-40°C to 85°C) and the LTC1799HS5#TRPBF for high-temperature operation (-40°C to 125°C). Verify electrical parameters remain identical across these variants.
