LTC1745CFW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1745CFW#TRPBF is a low noise, 12-bit, 25Msps analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes a pipelined architecture and 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, optimized for high-frequency signal digitization. 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 incorporates an internal reference and supports digital logic interfaces compatible with 5V, 3V, and 2V systems.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix '#TRPBF' against official documentation to confirm tape-and-reel packaging and lead-free status. Confirm that the 'C' temperature grade (0°C to 70°C) aligns with system requirements. Ensure compatibility with the TSSOP-48 package dimensions for board layout.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1745CFW#TRPBF when a 12-bit resolution at 25Msps is required with low jitter undersampling capabilities. Choose this component over the LTC1746 if lower power consumption is prioritized over higher resolution. Ensure the application can accommodate the ±1V or ±1.6V differential input range constraints.

Analog To Digital Converters (ADC) Part Context

The LTC1745 belongs to a pin-compatible family of ADCs from Analog Devices, including the LTC1746 (14-bit), LTC1744 (14-bit, 50Msps), and others up to 80Msps. This allows for design flexibility across different speed and resolution requirements while maintaining consistent footprint and interface compatibility within the same product line.
