• Selectable analog input ranges via the SENSE pin configuration
• Integrated clock duty cycle stabilizer for high-performance operation across varying clock signals
• Low power consumption with dedicated shutdown and nap modes

Analog To Digital Converters (ADC) Applications

• Wireless and wired broadband communication systems
• Cable head-end systems
• Power amplifier linearization
• Communications test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging with lead-free compliance. Confirm the C grade temperature range matches system requirements. Ensure the specific lot date code meets storage constraints. Validate that the QFN-48 footprint aligns with the PCB layout design rules.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution at 135Msps is required. Use the internal reference for simplified designs or external references for higher precision. Consider the LVDS or CMOS output interface based on downstream logic compatibility. Evaluate the 630mW power dissipation against thermal management capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2224 family of high-speed ADCs. It shares pin compatibility with the LTC2234 (10-bit), LTC2222 (12-bit, 105Msps), and other variants in the series. The #TRPBF designation specifically denotes the tape and reel packaging format for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2224UK (tube packaging) and the LTC2234 for lower resolution needs. Verify that any substitute maintains the 135Msps sampling rate and 12-bit resolution.
