LTC2152IUJ-14

Analog To Digital Converters (ADC) Overview

The LTC2152IUJ-14#PBF is a 14-bit, 250Msps analog-to-digital converter (ADC) from Analog Devices. It operates on a single 1.8V supply and features a 1.25GHz full-power bandwidth sample-and-hold circuit. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 70dB and a Spurious Free Dynamic Range (SFDR) of 90dB at 70MHz input. The device dissipates 356mW in standard operation, with low power sleep modes available. It utilizes DDR LVDS digital outputs and includes an internal reference, offering ±0.85LSB INL and ±0.25LSB DNL.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free finish and tube packaging. Confirm the 'I' grade designation for the -40°C to +85°C industrial temperature range. Ensure the ordering part number matches the required sampling speed variant, as other models in the family operate at lower speeds.

Analog To Digital Converters (ADC) Selection Notes

Select this model for high-speed applications requiring 250Msps. For lower speed requirements, consider the LTC2151-14 (210Msps) or LTC2150-14 (170Msps) which offer reduced power consumption. Ensure the design supports differential LVDS signaling and provides adequate bypassing for the 1.8V analog and output supplies.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC215x-14 family of high-performance ADCs. It shares pin compatibility with the 12-bit versions and offers trade-offs between sampling speed and power consumption within the series. The device is designed for demanding communications applications requiring wide dynamic range.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same package and pinout include the LTC2151IUJ-14#PBF (210Msps) and LTC2150IUJ-14#PBF (170Msps). These variants maintain the 14-bit resolution and interface but operate at lower maximum sampling frequencies.
