Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF indicates tape and reel packaging for the commercial temperature grade (0°C to 70°C). Confirm that the component matches the lead-free finish specification. Ensure the package type corresponds to the 64-lead 9mm x 9mm QFN format. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring high-speed digitization of wide dynamic range signals. Choose between LVDS or CMOS output modes based on interface requirements; CMOS allows adjustable swing from 0.5V to 2.625V via OVDD. Use the SENSE pin to configure internal reference ranges of ±0.5V or ±1V. Consider the pipeline latency of 5 cycles when designing system timing.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2242 family, which includes 10-bit and 12-bit variants operating at 250Msps. It is pin-compatible with the LTC2241 (210Msps) and LTC2240 (170Msps) series. The device shares the same 64-pin QFN package and core architecture across the speed grades, allowing for design flexibility within communication systems.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the LTC2242IUP-12#TRPBF for industrial temperature range (-40°C to 85°C). Lower speed options like the LTC2241-12 or LTC2240-12 may be used if sampling rate requirements are relaxed. Verify thermal performance differences between commercial and industrial grades.
