LTC6900CS5#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6900CS5#TRMPBF is a precision, low-power silicon oscillator manufactured by Analog Devices Inc. It operates on a single 2.7V to 5.5V supply and generates frequencies from 1kHz to 20MHz using a single external resistor (RSET). The device features a CMOS output driver with rail-to-rail switching and a typical supply current of 500µA at 3V. Frequency accuracy is specified at ≤1.5% maximum error between 5kHz and 10MHz at 25°C. It utilizes a proprietary feedback loop to linearize the relationship between resistance and frequency, eliminating the need for lookup tables.

Programmable Timers And Oscillators Feature Summary

• Frequency range of 1kHz to 20MHz set by a single external resistor
• High accuracy with frequency error ≤1.5% max (5kHz to 10MHz at 25°C)
• Low power consumption with typical supply current of 500µA at 3V
• Rail-to-rail CMOS output with fast rise/fall times

Programmable Timers And Oscillators Applications

• Portable and battery-powered equipment
• PDAs and cell phones
• Charge pump drivers
• Switching power supply clock references
• Fixed or ceramic crystal oscillator replacements

Programmable Timers And Oscillators Procurement Notes

Verify that the component matches the specific temperature grade 'C' (-40°C to 85°C) and the TSOT-23-5 package type. Confirm the ordering suffix '#TRMPBF' corresponds to the Tape and Reel packaging format required for automated assembly processes.

Programmable Timers And Oscillators Selection Notes

Select this model when a resistor-programmable oscillator is required within the 1kHz to 20MHz range. Ensure the application can accommodate an external resistor between 10kΩ and 2MΩ. Consider the divider setting (DIV pin) if specific frequency ranges below 500kHz are needed, as this affects master oscillator accuracy at lower supply voltages.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6900 family of silicon oscillators. The 'CS5' designation indicates the commercial temperature grade (-40°C to 85°C) and the S5 (TSOT-23-5) package. The '#TRMPBF' suffix specifies the lead-free finish and tape-and-reel packaging configuration.

Programmable Timers And Oscillators Replacement Considerations

The LTC1799 is a related part with identical pinout but offers higher frequency operation up to 30MHz. Other members of the LTC6900 family may share similar functionality but differ in temperature grades or package types.
