LTC1750CFW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1750CFW#PBF is a 14-bit, 80Msps wide bandwidth analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a 500MHz full-power sample-and-hold bandwidth and supports direct IF sampling up to 500MHz. The device includes an on-chip programmable gain amplifier (PGA) offering selectable input ranges of 2.25VP-P or 1.35VP-P. Key performance metrics include a signal-to-noise ratio (SNR) of 75.5dB and a spurious-free dynamic range (SFDR) of 90dB with the PGA set to unity gain. It operates on a single 5V supply with a typical power dissipation of 1.45W.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CFW' corresponds to the commercial temperature range (0°C to 70°C) and TSSOP-48 package as defined in the official datasheet. Confirm that the '#PBF' designation indicates lead-free compliance and RoHS adherence before procurement. Ensure the source documentation matches the manufacturer's current specifications for this part number.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1750CFW#PBF when a 14-bit resolution and 80Msps throughput are required for signals up to 500MHz. The internal PGA allows optimization of the input range without external amplifiers. Ensure the design accommodates a 1.45W power dissipation and provides adequate bypassing for the 5V analog and digital supplies. Verify that the host logic interface voltage levels match the OVDD configuration.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1750 family of high-speed ADCs. The 'C' suffix denotes the commercial operating temperature range, while 'FW' specifies the 48-lead plastic TSSOP package. The '#PBF' suffix indicates a lead-free finish compliant with RoHS standards. This part is designed for applications requiring wide dynamic range digitization.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the manufacturer for pin-for-pin compatible alternatives within the same family if different temperature grades or packaging options are required. No other specific substitute part numbers are confirmed in the provided documentation.
