AD9204BCPZRL7-40

Overview

The AD9204BCPZRL7-40 is a dual-channel, 10-bit analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum sampling rate of 40 MSPS with a single 1.8 V analog supply and a separate 1.7 V to 3.6 V digital output driver supply. The device features a differential input with a 700 MHz bandwidth and supports offset binary, gray code, or twos complement data formats. Key performance metrics include an SNR of 61.7 dBFS at a 9.7 MHz input frequency and an SFDR of 75 dBc under the same conditions. Power consumption is specified at 177 mW when operating at full speed with a 3.3 V digital supply.

Feature Summary

• Features a patented sample-and-hold circuit designed for low cost and ease of use while maintaining excellent performance for input frequencies up to 200 MHz.
• Includes a standard serial port interface (SPI) that supports various product features such as data output formatting, internal clock divider, power-down modes, and voltage reference selection.
• Offers flexible digital output options including programmable clock and data alignment, and the ability to multiplex data onto a single output bus.

Applications

• Communications systems
• Diversity radio systems
• Multimode digital receivers
• I/Q demodulation systems
• Smart antenna systems

Procurement Notes

Verify the specific ordering suffix RL7 indicates tape and reel packaging when placing orders. Confirm that the component meets RoHS compliance requirements for your manufacturing process. Ensure the selected variant matches the required 40 MSPS sampling rate specification for your design constraints.

Selection Notes

Select this model for applications requiring a 40 MSPS sampling rate with 10-bit resolution. Consider the LFCSP-64 package for space-constrained designs. Evaluate the power consumption against system thermal limits, noting the difference between 1.8 V and 3.3 V digital supply operation.

Part Context

This component belongs to the AD9204 family, which includes variants supporting 20 MSPS, 65 MSPS, and 80 MSPS rates. All members share the same 64-lead LFCSP pinout, facilitating migration between different speed grades within the same product line without redesigning the PCB layout.

Replacement Considerations

The AD9204BCPZ-40 is a tray-packaged equivalent. Other speed variants like the AD9204BCPZRL7-65 are pin-compatible but offer higher sampling rates.
