LTC2162IUK#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2162IUK#TRPBF is a 16-bit, 65Msps sampling analog-to-digital converter (ADC) from Analog Devices. It operates on a single 1.8V supply and dissipates 87mW with DC input or 92mW with sine wave input. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 77dB and a Spurious Free Dynamic Range (SFDR) of 90dB at 70MHz input frequency. The device features an ultralow jitter of 0.07ps RMS, enabling effective undersampling of intermediate frequencies. It offers selectable input ranges of 1VP-P to 2VP-P and supports full-rate CMOS, double data rate (DDR) CMOS, or DDR LVDS digital output interfaces.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'I' suffix indicates the industrial temperature range (-40°C to 85°C). Confirm the '#TRPBF' suffix denotes tape and reel packaging with lead-free finish. Ensure compatibility with the 48-lead QFN package dimensions during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this model for high-frequency signal digitization requiring low power and high dynamic range. Compare against LTC2161 (40Msps) or LTC2160 (25Msps) if lower sampling rates suffice. Verify that the required digital interface (CMOS vs LVDS) matches the system design, as output mode selection affects power dissipation significantly.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC216x family of low-power, high-speed ADCs. The 'I' grade specifies industrial operating temperatures, while the 'UK' package code identifies the 48-lead 7mm x 7mm plastic QFN form factor. The part is designed for demanding communications applications where AC performance and power efficiency are critical.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2161IUK#TRPBF (40Msps), LTC2160IUK#TRPBF (25Msps). These variants share the same package and pinout but offer reduced sampling speeds.
