LTC2269CUK#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2269CUK#TRPBF is a 16-bit, 20Msps sampling analog-to-digital converter (ADC) designed for high-frequency, wide dynamic range signal digitization. It operates on a single 1.8V supply with typical power dissipation of 88mW. Key AC performance metrics include an 84.1dB Signal-to-Noise Ratio (SNR) and 99dB Spurious Free Dynamic Range (SFDR). DC specifications feature ±1LSB typical Integral Non-Linearity (INL) and ±0.2LSB typical Differential Non-Linearity (DNL). The device supports selectable input ranges from 1V to 2.1V peak-to-peak and offers full-rate CMOS, double data rate CMOS, or double data rate LVDS digital output options.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix '#TRPBF' confirms the tape and reel packaging format required for automated assembly. Confirm the 'C' grade designation matches the intended operating temperature range of 0°C to 70°C. Ensure the 48-lead QFN package dimensions align with the target PCB footprint and thermal management requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when low power consumption is critical alongside high dynamic range requirements. Choose between CMOS and LVDS output modes based on system noise immunity and trace count constraints. Utilize the serial SPI interface for flexible configuration of input ranges and output formats without additional hardware logic.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2269 family of 16-bit high-speed ADCs. It is pin-compatible with the LTC2160, which offers a slightly higher sampling rate of 25Msps but different power characteristics. The device integrates internal references and clock duty cycle stabilization to simplify system design.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2160 is a pin-compatible alternative offering 25Msps sampling speed. Verify if the increased speed meets system requirements and if the power profile remains within acceptable limits for the application.
