AD9204BCPZ-40

Overview

The AD9204BCPZ-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 differential input bandwidth of 700 MHz. The device uses a single 1.8 V analog supply and supports digital output driver supplies from 1.7 V to 3.6 V. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 61.7 dBFS at a 9.7 MHz input frequency and a Spurious-Free Dynamic Range (SFDR) of 75 dBc under the same conditions. Differential Nonlinearity (DNL) is specified at ±0.3 LSB, while Integral Nonlinearity (INL) is ±0.6 LSB. Power consumption is 177 mW when operating at full speed with a 3.3 V digital supply.

Feature Summary

• Features a multistage differential pipeline architecture with output error correction logic for high accuracy.
• Includes an on-chip voltage reference and sample-and-hold circuit designed for low power operation.
• Supports flexible data formatting options including offset binary, gray code, or twos complement.
• Provides a serial port interface (SPI) for programmable clock alignment, power-down modes, and test pattern generation.

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for moisture sensitivity level requirements during storage and handling. Ensure the ordering suffix matches the required package type and temperature range specifications before finalizing procurement orders.

Selection Notes

Select this model for applications requiring dual-channel conversion at speeds up to 40 MSPS. Consider the AD9204BCPZ-20 for lower speed needs or the AD9204BCPZ-65/80 variants if higher throughput is necessary. Ensure the system design accommodates the 64-lead LFCSP package dimensions and thermal dissipation requirements for the exposed paddle ground connection.

Part Context

This component belongs to the AD9204 family of dual-channel ADCs. It shares pin compatibility with other members of the series, such as the AD9268 and AD9251, facilitating migration between different resolution and speed grades within the same package footprint. The device is part of Analog Devices' portfolio of low-power, high-speed data converters.

Replacement Considerations

Direct replacements within the same package and functionality include the AD9204BCPZ-20, AD9204BCPZ-65, and AD9204BCPZ-80. These variants offer different sampling rates but maintain pin compatibility. Verify specific electrical parameter differences against the datasheet before substitution.
