LTC2151IUJ-14

Analog To Digital Converters (ADC) Overview

The LTC2151IUJ-14 is a 14-bit, 210Msps analog-to-digital converter (ADC) from Analog Devices. It utilizes a pipeline architecture with DDR LVDS outputs and operates on a single 1.8V supply. Key electrical parameters include a full-power bandwidth of 1.25GHz, typical SNR of 68.0dBFS at 70MHz input, and SFDR of 90.1dBFS. Power dissipation is 333mW in standard mode, reducing to 99mW in Nap mode and under 2mW in Sleep mode. The device features an internal reference, optional clock duty cycle stabilizer, and serial SPI configuration interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free finish and tube packaging when sourcing. Confirm the 'I' grade designation corresponds to the -40°C to +85°C industrial temperature range. Ensure the ordering part number matches the required 14-bit variant, as the datasheet primarily details the 12-bit family members.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range at moderate high speeds. Compare against the LTC2152-14 for higher 250Msps throughput or LTC2150-14 for lower 170Msps power optimization. Verify that the 1.5VP-P input range and differential drive requirements align with the front-end amplifier capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC215x-14 family, which shares pin compatibility and architectural similarities with the LTC215x-12 series. The primary distinction is the increased resolution from 12 to 14 bits, resulting in slightly different power and noise characteristics while maintaining the same 40-lead QFN package form factor.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC2152IUJ-14#PBF (250Msps) and LTC2150IUJ-14#PBF (170Msps). Verify that the specific speed and power trade-offs meet the system requirements before substituting.
