LTC2164IUK#PBF

Analog To Digital Converters (ADC) Overview

The LTC2164IUK#PBF is a 16-bit, 105Msps low-power analog-to-digital converter (ADC) from Analog Devices. It features an ultralow jitter of 0.07ps RMS and supports selectable input ranges of 1Vp-p to 2Vp-p. The device operates on a single 1.8V supply with typical power dissipation of 163mW at full speed. Digital outputs are available in full-rate CMOS, double data rate (DDR) CMOS, or DDR LVDS formats. Key performance metrics include a signal-to-noise ratio (SNR) of 76.8dB and a spurious-free dynamic range (SFDR) of 90dB.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free finish and tube packaging when sourcing. Confirm the 'I' grade designation ensures operation within the –40°C to +85°C industrial temperature range. Ensure the selected variant matches the required sampling speed and output interface configuration for the target application.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2164IUK#PBF over the LTC2165 or LTC2163 variants based on the required sampling frequency; this model is optimized for 105Msps. Choose the appropriate digital output mode (CMOS vs. LVDS) based on board trace length and noise immunity requirements. Verify that the system clock duty cycle stabilizer is utilized if the input clock duty cycle deviates significantly from 50%.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC216x family of 16-bit low-power ADCs. The LTC2164 specifically targets applications requiring 105Msps throughput, bridging the gap between the 125Msps LTC2165 and the 80Msps LTC2163. All three share identical pinouts and architectural features, differing primarily in maximum sampling rates and associated power consumption profiles.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same package and specification profile include the LTC2165IUK#PBF (higher speed, 125Msps) and the LTC2163IUK#PBF (lower speed, 80Msps). These parts are pin-compatible but require verification of power budget and timing constraints.
