LTC2152CUJ-12#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2152CUJ-12#TRPBF is a single-channel, 12-bit analog-to-digital converter (ADC) operating at a sampling rate of 250 Msps. It utilizes a pipelined architecture with DDR LVDS digital outputs and requires a single 1.8V supply. Key electrical specifications include a full-power bandwidth of 1.25 GHz, a signal-to-noise ratio (SNR) of 68.5 dBFS, and a spurious-free dynamic range (SFDR) of 90 dBFS. The device features an easy-to-drive 1.5 Vp-p differential input range, low power dissipation of 347 mW, and an internal reference. It is housed in a 40-lead (6mm × 6mm) QFN package.

Analog To Digital Converters (ADC) Feature Summary

• Dual-data-rate (DDR) LVDS digital output interface for high-speed data transfer
• Low power consumption of 347 mW with dedicated Sleep and Nap modes
• Integrated 1.25 GHz sample-and-hold full-power bandwidth supporting undersampling applications

Analog To Digital Converters (ADC) Applications

• Cellular base stations
• Software-defined radios
• Medical imaging systems
• High-definition video processing
• Testing and measurement instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging rather than tube packaging. Confirm the 'C' grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure the source document explicitly lists this part number as available from Analog Devices or authorized distributors before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2152 variant over the LTC2151 or LTC2150 if the application requires the highest sampling speed of 250 Msps. Consider the LTC2152IUJ-12#TRPBF if operation below 0°C is required, as it covers the industrial temperature range. Verify that the system can accommodate the 1.8V supply requirement and DDR LVDS signaling constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC215x-12 family of high-speed ADCs, which also includes the LTC2151-12 (210 Msps) and LTC2150-12 (170 Msps). All members share pin compatibility and similar architectural features, differing primarily in their maximum sampling rates and associated power consumption profiles.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2151CUJ-12#TRPBF and LTC2150CUJ-12#TRPBF are pin-compatible alternatives within the same family. They offer lower sampling rates (210 Msps and 170 Msps respectively) and reduced power consumption but cannot replace the LTC2152 if the design strictly requires 250 Msps performance.
