LTC2242CUP-10#PBF

Analog To Digital Converters (ADC) Overview

The LTC2242CUP-10#PBF is a 10-bit, 250Msps pipelined analog-to-digital converter (ADC) designed for high-frequency signal digitization. It operates on a single 2.5V supply with typical power dissipation of 740mW in CMOS mode. Key AC performance metrics include a Signal-to-Noise Ratio (SNR) of 60.5dB and Spurious Free Dynamic Range (SFDR) of 78dB at 250Msps. The device features ultralow jitter of 95fs RMS, enabling effective IF undersampling. DC specifications guarantee ±0.4LSB Integral Nonlinearity (INL) and ±0.2LSB Differential Nonlinearity (DNL) with no missing codes across the operating temperature range.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix #PBF indicates a lead-free finish and tube packaging. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the specific lot marking matches the datasheet requirements for lead-free identification.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution at 250Msps is required. Choose between LVDS or CMOS output interfaces based on downstream receiver compatibility. Use the SENSE pin to configure the desired analog input range (±0.5V or ±1V). Consider the exposed pad thermal requirements for the 64-pin QFN package during PCB layout.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2242 family, which includes pin-compatible variants such as the LTC2242-12 (12-bit) and other speed grades like the LTC2241 (210Msps) and LTC2240 (170Msps). The 'I' grade variant offers an extended industrial temperature range (-40°C to 85°C), while the 'C' grade is limited to commercial temperatures.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC2242-12 for higher resolution or the LTC2241-10 for lower speed applications. Verify that the alternative part's voltage levels and output formats match the existing design constraints.
