Description
The LTC6908IS6-1 is a low-power, precision oscillator from Analog Devices, designed to generate a fixed frequency of 1MHz with high accuracy (±1.5%). Housed in a compact SOT-23-6 package, it operates from a 2.7V to 5.5V supply, making it suitable for battery-powered and space-constrained applications.
Key features include:
- Low power consumption (~1.2mA at 5V).
- No external components required (internal resistor sets frequency).
- Low jitter (<0.5% period jitter).
- Wide temperature range (−40°C to +125°C).
Ideal for clocking ADCs, microcontrollers, or as a timing reference in portable and industrial systems. Its simplicity and reliability make it a popular choice for designers needing a stable, fixed-frequency oscillator.

Pinout
The LTC6908IS6-1 is a 6-pin SOT-23 package oscillator with the following pin functions:
1. GND (Pin 1) – Ground connection.
2. SET (Pin 2) – Frequency-setting resistor input.
3. V+ (Pin 3) – Positive supply voltage (2.7V to 5.5V).
4. DIV (Pin 4) – Frequency divider control (logic input).
5. OUT (Pin 5) – Oscillator output (square wave).
6. NC (Pin 6) – No connection (unused).
It generates a fixed 1MHz output frequency when DIV is left open or tied high. The frequency can be divided down by tying DIV to GND (e.g., 500kHz).
