LTC2201IUK#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2201IUK#TRPBF is a 16-bit, 20Msps analog-to-digital converter (ADC) designed for digitizing high-frequency signals up to 380MHz. It features a single 3.3V supply and dissipates 211mW. Key performance metrics include an 81.6dB Signal-to-Noise Ratio (SNR) and 100dB Spurious Free Dynamic Range (SFDR). The device incorporates a Programmable Gain Amplifier (PGA) front end with selectable input ranges of 2.5VP-P or 1.667VP-P. It utilizes a pipelined architecture with internal reference generation and operates within an industrial temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF confirms tape and reel packaging and lead-free finish. Confirm the I suffix indicates the –40°C to 85°C industrial operating temperature range. Ensure the QFN package dimensions match the PCB footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range at moderate sampling speeds. The internal PGA allows optimization for specific input voltage levels without external gain stages. Consider the 7-cycle pipeline latency when designing timing-critical digital interfaces.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2201 family, which includes pin-compatible variants such as the LTC2202 (10Msps) and LTC2203 (25Msps). These devices share the same 48-pin QFN package and interface logic, facilitating design upgrades or downgrades within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the LTC2202CUK#TRPBF and LTC2203IUK#TRPBF. Verify that the sampling rate and power consumption of the substitute meet the system requirements before replacement.
