LTC2272IUJ#PBF

Analog To Digital Converters (ADC) Overview

The LTC2272IUJ#PBF is a 16-bit, 65Msps analog-to-digital converter featuring a high-speed serial interface compliant with the JESD204 specification. It incorporates an internal programmable gain amplifier (PGA) allowing for selectable input ranges of 1.5Vp-p or 2.25Vp-p. The device operates on a single 3.3V supply and dissipates approximately 990mW at full speed. Key electrical specifications include a spurious-free dynamic range (SFDR) exceeding 100dBc at low frequencies, a noise floor of 77.7dBFS, and ultra-low internal jitter of 80fs RMS. It utilizes a 40-lead 6mm × 6mm QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific temperature grade suffix when ordering. The 'I' designation indicates an industrial operating range of –40°C to +85°C. Confirm that the '#PBF' suffix corresponds to lead-free packaging and tube shipping format as specified in the manufacturer's ordering information table.

Analog To Digital Converters (ADC) Selection Notes

Select this component over the LTC2273 if the application requires a maximum sampling rate of 65Msps rather than 80Msps. Both devices share pin compatibility and architectural features. Ensure the system design accommodates the 990mW power dissipation typical for the 65Msps operation mode.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC227x family of high-speed serial ADCs. It is functionally identical to the LTC2273 except for the reduced maximum sample rate of 65Msps compared to the LTC2273's 80Msps. The family shares the same 40-pin QFN footprint and JESD204 interface logic.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2273 is a pin-compatible alternative offering a higher sampling rate of 80Msps. The LTC2274 provides 105Msps performance within the same package.
