LTC2220IUP-1#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2220IUP-1#TRPBF is a 12-bit, 185Msps pipelined analog-to-digital converter (ADC) from Analog Devices. It operates on a single 3.3V supply with typical power dissipation of 910mW in CMOS mode. The device features an ultralow jitter of 0.15ps RMS and supports differential or single-ended analog inputs. Digital outputs are configurable as full-rate CMOS, demultiplexed CMOS, or LVDS. Key AC performance metrics include a Signal-to-Noise Ratio (SNR) of 67.5dB and a Spurious Free Dynamic Range (SFDR) of 80dB at input frequencies up to 170MHz. The component is housed in a 64-lead 9mm × 9mm QFN package.

Analog To Digital Converters (ADC) Feature Summary

• 185Msps sampling rate with 12-bit resolution and no missing codes over temperature
• Low power consumption of 910mW (CMOS mode) on a single 3.3V supply
• Configurable digital outputs: Full-rate CMOS, Demultiplexed CMOS, or LVDS
• Ultralow aperture jitter of 0.15ps RMS for high-frequency undersampling

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 Lead-Free Tape and Reel packaging. Confirm the 'I' grade designation corresponds to the -40°C to +85°C operating temperature range. Ensure the order number matches the specific speed grade (LTC2220-1) rather than other variants in the family.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring high-speed digitization with low jitter. Choose between CMOS and LVDS output modes based on interface requirements; LVDS offers better noise immunity but requires termination resistors. Verify that the analog input common-mode voltage (1.6V typical) aligns with the driver circuit capabilities.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2220-1 family, which includes pin-compatible variants such as the LTC2220 (185Msps), LTC2230 (10-bit), and slower speeds like the LTC2221 (135Msps). All share the same 64-pin QFN footprint and functional block architecture, differing primarily in resolution and maximum sampling frequency.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same package include the LTC2220IUP-1#PBF (tube packaging) and other speed grades like the LTC2221IUP-1#TRPBF. Direct substitutes outside the family require verification of pinout compatibility and electrical parameter alignment.
