LTC2205IUK#PBF

Analog To Digital Converters (ADC) Overview

The LTC2205IUK#PBF is a 16-bit, 65Msps sampling analog-to-digital converter designed for high-frequency signal digitization up to 700MHz. It features an internal programmable gain amplifier (PGA) allowing input ranges of 1.5VP-P or 2.25VP-P. Key AC performance metrics include 79dB SNR and 100dB SFDR at full scale, with ultralow jitter of 90fs RMS. DC specifications guarantee ±4LSB INL and ±1LSB DNL without missing codes. The device operates on a single 3.3V supply, dissipating 610mW, and supports independent digital output voltage ranging from 0.5V to 3.6V via the OVDD pin.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'I' suffix indicates the industrial temperature range of –40°C to 85°C. Confirm the '#PBF' designation corresponds to lead-free finish and tape and reel packaging options if required. Ensure the 48-lead QFN package dimensions match the PCB footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 65Msps throughput with 16-bit precision. Compare against the LTC2204 (40Msps) if lower power is critical, or the LTC2207 (105Msps) for higher speed. Verify that the 700MHz input bandwidth meets the highest frequency component of the signal being sampled.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC220x family of 16-bit ADCs. It shares pin compatibility with the LTC2204 (40Msps), LTC2206 (80Msps), and LTC2207 (105Msps). The 'I' grade specifies operation from –40°C to 85°C, while the 'C' grade covers 0°C to 70°C. All variants utilize the same 48-pin QFN package.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2204IUK#PBF (40Msps), LTC2206IUK#PBF (80Msps), and LTC2207IUK#PBF (105Msps). Substitution requires verification of sampling rate and power dissipation limits.
