LTC2205IUK#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2205IUK#TRPBF is a 16-bit, 65Msps analog-to-digital converter (ADC) housed in a 48-lead (7mm × 7mm) plastic QFN package. It features a pipeline architecture with an integrated programmable gain amplifier (PGA) and internal reference generator. The device operates on a single 3.3V supply with a power dissipation of 610mW. Key electrical specifications include a signal-to-noise ratio (SNR) of 79dB and a spurious-free dynamic range (SFDR) of 100dB at a 2.25VP-P input range. It supports differential or single-ended inputs with a full power bandwidth of 700MHz and an ultralow jitter of 90fs RMS.

Analog To Digital Converters (ADC) Procurement Notes

Verify the I suffix indicates an industrial temperature range of –40°C to 85°C. Confirm the #TRPBF designation specifies lead-free finish and tape and reel packaging. Ensure compatibility with the 48-pin QFN footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this model for high-speed applications requiring 16-bit precision at 65Msps. Compare against the LTC2204 if a lower 40Msps rate suffices. Consider the LTC2206 or LTC2207 families if higher sampling speeds are required. Verify that the 700MHz full power bandwidth meets the specific input frequency requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2205/LTC2204 family of high-speed ADCs. It is pin-compatible with the LTC2206 (80Msps) and LTC2207 (105Msps) series, allowing for design scalability across different speed requirements while maintaining the same 48-pin QFN form factor.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2204 offers identical functionality at a reduced 40Msps sampling rate. For higher throughput, the LTC2206 (80Msps) and LTC2207 (105Msps) provide pin-compatible upgrades within the same package.
