LTC2170CUKG-12#PBF

Analog To Digital Converters (ADC) Overview

The LTC2170CUKG-12#PBF is a 4-channel, simultaneous sampling 12-bit analog-to-digital converter (ADC) from Analog Devices. Operating at a maximum sampling rate of 25Msps, it features an ultralow jitter of 0.15psRMS and delivers 71dB SNR with 90dB SFDR. The device utilizes serial LVDS outputs and supports selectable input ranges of 1VP-P to 2VP-P. Powered by a single 1.8V supply, total power dissipation is 160mW in 2-lane mode. It is housed in a 52-pin QFN package and operates within a commercial temperature range of 0°C to 70°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix #PBF indicates lead-free finish and tube packaging. Confirm the 'C' grade corresponds to the 0°C to 70°C operating range. Ensure the specific speed grade matches the 25Msps requirement for the LTC2170 variant rather than higher-speed siblings.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring four synchronized channels at moderate speeds up to 25Msps. Compare against LTC2171-12 (40Msps) or LTC2172-12 (65Msps) if higher throughput is needed. Verify that the 1.8V single-supply architecture fits the system power budget.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC217x-12 family of low-power quad ADCs. It shares pin compatibility with 14-bit versions and other speed grades within the same series. The device is designed for digitizing high-frequency, wide dynamic range signals in demanding communications environments.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2171CUKG-12#PBF offers 40Msps performance. LTC2172CUKG-12#PBF provides 65Msps. Both are pin-compatible but consume more power. For 14-bit resolution, consider LTC2170CUKG-14#PBF.
