LTC2223IUK#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2223IUK#TRPBF is a 12-bit, 80Msps pipelined analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates on a single 3.3V supply with a typical power dissipation of 366mW. The device features an ultralow jitter of 0.15ps RMS and supports selectable input ranges of ±0.5V or ±1V via the SENSE pin. Key performance metrics include a Signal-to-Noise Ratio (SNR) of up to 68.5dB and a Spurious Free Dynamic Range (SFDR) of up to 84dB for inputs up to 170MHz. It utilizes a 48-lead 7mm × 7mm plastic QFN package.

• Ultralow aperture delay jitter of 0.15ps RMS for high-frequency undersampling
• Selectable differential input ranges of ±0.5V or ±1V controlled by the SENSE pin
• Integrated clock duty cycle stabilizer and optional shutdown/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 specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'I' grade designation corresponds to the –40°C to 85°C industrial temperature range required for the application environment. Ensure compatibility with the 48-lead QFN footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2223IUK#TRPBF over the LTC2222 variant when an 80Msps sampling rate is sufficient, as it offers lower power consumption (366mW vs 475mW). Verify that the required input frequency does not exceed the 170MHz limit for optimal SFDR performance. Consider the 5-cycle pipeline latency when designing timing-critical digital interfaces.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2222/LTC2223 family of high-speed ADCs. It is pin-compatible with the 105Msps LTC2222 and the 135Msps LTC2224. The family shares the same 48-pin QFN package and functional block diagram, differing primarily in maximum sampling speed and associated power dissipation characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2222IUK#TRPBF serves as a higher-speed alternative within the same package. For 10-bit resolution requirements at similar speeds, the LTC2233IUK#TRPBF is a compatible option. Verify that any substitute maintains the 48-lead QFN form factor and electrical interface compatibility.
