LTC2270IUP#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2270IUP#TRPBF is a dual-channel, 16-bit, 20Msps analog-to-digital converter (ADC) designed for low power instrumentation and software-defined radios. It operates on a single 1.8V supply with total power dissipation of 160mW. Key performance metrics include an 84.1dB Signal-to-Noise Ratio (SNR), 99dB Spurious-Free Dynamic Range (SFDR), and ±2.3LSB maximum Integral Non-Linearity (INL). The device features selectable input ranges from 1V to 2.1V peak-to-peak and supports CMOS, DDR CMOS, or DDR LVDS digital output interfaces.

Analog To Digital Converters (ADC) Feature Summary

• Two-channel simultaneous sampling architecture with 16-bit resolution
• Low noise performance: 84.1dB SNR and 46μV RMS input-referred noise
• Configurable digital outputs: Full-rate CMOS, Double Data Rate CMOS, or DDR LVDS

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 specifies tape and reel packaging. Ensure compatibility with the 64-lead QFN footprint and soldering requirements for the exposed ground pad.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous dual-channel conversion at 20Msps is required. Choose between CMOS, DDR CMOS, or LVDS outputs based on interface speed and noise sensitivity. Verify that the 1.8V single-supply operation fits the system power budget.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2270 family of high-speed ADCs. It is pin-compatible with the LTC2180 (16-bit, 25Msps) and LTC2140-14 (14-bit, 25Msps), allowing for design upgrades or downgrades without PCB layout changes.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the LTC2180IUP#TRPBF and LTC2140-14IUP#TRPBF. These parts offer different speed and resolution trade-offs while maintaining the same 64-lead QFN package.
