LTC2204IUK#PBF

Analog To Digital Converters (ADC) Overview

The LTC2204IUK#PBF is a 16-bit, 40Msps analog-to-digital converter (ADC) from Analog Devices. It features a pipeline architecture with an internal reference generator and a programmable gain amplifier (PGA) front end. The device operates on a single 3.3V supply with a power dissipation of 480mW. Key electrical specifications include a full-power bandwidth of 700MHz, a signal-to-noise ratio (SNR) of 79dB, and a spurious-free dynamic range (SFDR) of 100dB. It utilizes a parallel CMOS interface and is housed in a 48-lead QFN package.

Analog To Digital Converters (ADC) Applications

• Telecommunications
• Cellular Base Stations
• Spectrum Analysis
• Imaging Systems
• Automatic Test Equipment (ATE)

Analog To Digital Converters (ADC) Procurement Notes

Verify the I suffix indicates an industrial temperature range of -40°C to +85°C. Confirm the #PBF designation ensures lead-free compliance. Check for availability of the tape and reel variant (LTC2204IUK#TRPBF) if automated assembly is required. Ensure the 48-pin QFN footprint matches the PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2205 when a 40Msps sampling rate is sufficient, as it offers lower power consumption (480mW vs 610mW). The internal PGA allows optimization for specific input voltage ranges without external components. Verify that the parallel digital interface meets the system's timing requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2205/LTC2204 family of high-speed ADCs. It shares pin compatibility with the LTC2206 (80Msps) and LTC2207 (105Msps) series. The device is designed for applications requiring wide dynamic range and high linearity at high frequencies.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2205IUK#PBF: Higher speed (65Msps), higher power (610mW). LTC2206IUK#PBF: Higher speed (80Msps). LTC2207IUK#PBF: Highest speed (105Msps). All share the same package and pinout.
