AD9251BCPZRL7-80

Overview

The AD9251BCPZRL7-80 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Analog Devices Inc. It operates at a maximum sampling rate of 80 MSPS with a single 1.8 V analog supply and a separate 1.8 V to 3.3 V digital output driver supply. The device features a differential analog input with a 2 V p-p span and a 700 MHz bandwidth. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 74.3 dBFS at a 9.7 MHz input frequency and a Spurious-Free Dynamic Range (SFDR) of 93 dBc under the same conditions. Power consumption is specified at 86 mW per channel at 80 MSPS. The component is housed in a 64-lead Lead Frame Chip Scale Package (LFCSP).

Feature Summary

• Multistage differential pipeline architecture with integrated output error correction logic.
• On-chip voltage reference and high-performance sample-and-hold circuit.
• Serial Port Interface (SPI) for programmable configuration and control.
• Supports offset binary, gray code, or twos complement data formats.

Applications

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

Procurement Notes

Verify the specific ordering suffix RL7 against official documentation to confirm reel packaging specifications. Ensure compatibility with the target system's power supply requirements and signal interface standards before procurement.

Selection Notes

Select this model for applications requiring low power consumption and high dynamic range at 80 MSPS. Verify that the 1.8 V analog supply and compatible digital logic levels meet the design constraints. Consider the LFCSP package size for space-constrained PCB layouts.

Part Context

This component belongs to the AD9251 family of dual-channel ADCs. It shares pinout compatibility with other devices in the series, such as the AD9268, AD9258, AD9231, and AD9204, facilitating migration between different resolution and speed grades within the product line.

Replacement Considerations

The AD9251BCPZ-80 is a pin-compatible alternative within the same family. Verify if the non-reel packaging variant meets the assembly requirements.
