LTC6908IS6-1

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.

The LTC6908IS6-1 is a precision oscillator. Equivalent alternatives include:
- LTC6909: Similar precision, adjustable frequency.
- MAX7375: Fixed-frequency oscillator.
- SiT8008B: Low-jitter oscillator.
- DS1077: Programmable oscillator.
Check datasheets for exact specs like frequency range, voltage, and package compatibility. For exact drop-in replacements, consult distributors like Analog Devices (now part of ADI) or parametric search tools.

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).

The LTC6908IS6-1 is manufactured by Linear Technology Corporation, now part of Analog Devices, Inc. after its acquisition in 2017.
Linear Technology was a leading semiconductor company specializing in high-performance analog integrated circuits, including power management, data conversion, and signal conditioning products. Known for innovation and reliability, its components are widely used in industrial, automotive, and communications applications.
Analog Devices (ADI) is a global leader in analog, mixed-signal, and DSP technologies, continuing Linear Technology's legacy of precision analog solutions.
The LTC6908IS6-1 is a low-power, precision oscillator from this product line.

The LTC6908IS6-1 comes in a 6-lead TSOT-23 package. This small, surface-mount package is compact and suitable for space-constrained applications. It features a low-profile design, making it ideal for portable and high-density PCB layouts. The TSOT-23 package is commonly used for precision analog and mixed-signal ICs.
