LTC2184CUP

Analog To Digital Converters (ADC) Overview

The LTC2184CUP is a dual-channel, simultaneous-sampling 16-bit analog-to-digital converter (ADC) from Analog Devices. It operates at a sampling rate of 105Msps and utilizes a proprietary conversion architecture housed in a 64-lead QFN package. The device features an ultralow jitter specification of 0.07ps RMS, enabling high-performance undersampling of intermediate frequency signals. Key electrical characteristics include a typical signal-to-noise ratio (SNR) of 76.8dB and a spurious-free dynamic range (SFDR) of 90dB. DC accuracy is defined by ±2LSB integral nonlinearity (INL) and ±0.5LSB differential nonlinearity (DNL).

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel simultaneous sampling with 16-bit resolution and 105Msps throughput.
• Ultralow jitter of 0.07ps RMS for superior wideband noise performance.
• Flexible digital output options including full-rate CMOS, DDR CMOS, or DDR LVDS.
• Low power consumption design suitable for battery-operated systems.

Analog To Digital Converters (ADC) Applications

• Software-defined radio (SDR)
• Wireless local loop infrastructure
• Point-to-point microwave backhaul

Analog To Digital Converters (ADC) Part Context

The LTC2184CUP belongs to the LTC218x family of low-power dual ADCs, which also includes the higher-speed LTC2185 (125Msps) and lower-speed LTC2183 (80Msps). These components share identical pinouts and functional architectures, differing primarily in their maximum sampling rates to accommodate various bandwidth requirements in communication systems.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2185CUP and LTC2183CUP are direct pin-compatible replacements within the same series. Selection depends on whether the application requires the increased speed of the LTC2185 or the reduced power of the LTC2183. Verify that the specific JESD204B interface version matches system requirements.
