AD9653BCPZRL7-125

Analog To Digital Converters (ADC) Overview

The AD9653BCPZRL7-125 is a quad, 16-bit, 125 MSPS analog-to-digital converter (ADC) with an on-chip sample-and-hold circuit. It operates from a single 1.8 V supply and features serial LVDS outputs compatible with ANSI-644 or reduced range standards. The device provides a 650 MHz full-power analog bandwidth and supports differential input voltage ranges of 2.0 V p-p to 2.6 V p-p. Key performance metrics include a Signal-to-Noise Ratio (SNR) of up to 80 dBFS at 9.7 MHz and a Spurious-Free Dynamic Range (SFDR) of 96 dBc. It includes built-in digital test pattern generation, programmable output clock alignment, and individual channel power-down modes.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 against the manufacturer's current documentation to confirm reel packaging specifications and tape dimensions. Ensure compatibility with existing PCB footprints for the 48-lead LFCSP package. Confirm that the industrial temperature range meets system requirements. Cross-reference the part number with official distributors to validate authenticity and revision status before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a small footprint and low power are critical alongside high dynamic performance. It is pin-compatible with the AD9253 and AD9633, facilitating design upgrades. Consider the serial LVDS interface if reducing trace count compared to parallel architectures is necessary. Evaluate the 1.8 V supply requirement and ensure the system clock supports the required LVPECL/CMOS/LVDS compatibility.

Analog To Digital Converters (ADC) Part Context

The AD9653 belongs to Analog Devices' family of high-speed, low-power analog-to-digital converters. It is designed for applications requiring multiple channels in a space-constrained environment. The device utilizes a pipeline architecture optimized for outstanding dynamic performance. It represents a solution for systems needing simultaneous multi-channel acquisition with minimal external components.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9653 is pin-compatible with the AD9253 (14-bit quad) and AD9633 (12-bit quad). When replacing these parts, verify that the resolution difference does not impact system accuracy. Ensure that the target application can accommodate the 16-bit resolution and 125 MSPS speed without exceeding power budgets.
