LTC2163CUK#PBF

Analog To Digital Converters (ADC) Overview

The LTC2163CUK#PBF is a 16-bit, 80Msps sampling analog-to-digital converter (ADC) from Analog Devices. It operates on a single 1.8V supply and dissipates 108mW with a sine wave input. The device features an ultralow jitter of 0.07ps RMS, enabling high-performance undersampling. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 76.9dBFS at 5MHz input and a Spurious Free Dynamic Range (SFDR) of 90dBFS. It offers selectable input ranges of 1VP-P to 2VP-P and supports full-rate CMOS, double data rate CMOS, or double data rate LVDS digital outputs.

Analog To Digital Converters (ADC) Applications

• Communications systems
• Cellular base stations
• Software defined radios
• Portable medical imaging
• Multichannel data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the 'C' grade designation corresponds to the commercial operating temperature range of 0°C to 70°C. Ensure the specific part number matches the required 80Msps speed variant within the LTC216x family.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 80Msps sampling rate is sufficient for the application, as opposed to the faster LTC2164 (105Msps) or LTC2165 (125Msps). Choose the CUk package for the 48-lead QFN form factor. Verify that the required output interface (CMOS or LVDS) and input voltage range (1VP-P or 2VP-P) align with system constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2165/LTC2164/LTC2163 family of low-power 16-bit ADCs. The primary distinction between these models is the maximum sampling frequency: 125Msps for LTC2165, 105Msps for LTC2164, and 80Msps for LTC2163. All variants share identical pinouts, architecture, and dynamic performance characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2164CUK#PBF and LTC2165CUK#PBF are pin-compatible upgrades offering higher sampling rates (105Msps and 125Msps respectively) while maintaining the same package and functionality.
