LTC1745IFW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1745IFW#PBF is a 12-bit, 25Msps pipelined analog-to-digital converter (ADC) from Analog Devices Inc. It operates on a single 5V supply with a power dissipation of 380mW. The device features pin-selectable differential input ranges of ±1V or ±1.6V and includes an internal 2.35V reference. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 72.5dB and a Spurious Free Dynamic Range (SFDR) of 91dB at a 5MHz input frequency using the 3.2V range. It utilizes a 48-lead TSSOP package and supports digital logic interfaces compatible with 5V, 3V, and 2V systems.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IFW' confirms the industrial temperature range (-40°C to +85°C) and TSSOP-48 package. Confirm RoHS compliance status as indicated in official documentation. Check current lifecycle status, as older ADC models may be subject to obsolescence notices.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1745 when 12-bit resolution at 25Msps is sufficient for the application. Choose this part over the LTC1746 if lower power consumption is prioritized over higher 14-bit resolution. Ensure the source impedance is matched to 50Ω for optimal SFDR performance.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC174x family of low noise, high-speed ADCs. It shares pin compatibility with other members such as the LTC1746 (14-bit), LTC1744 (14-bit, 50Msps), and LTC1742 (14-bit, 65Msps), allowing for design flexibility across different speed and resolution requirements within the same package footprint.
