AD9215BRUZ-65

Overview

The AD9215BRUZ-65 is a monolithic, single-channel, 10-bit analog-to-digital converter (ADC) from Analog Devices Inc. It operates at a maximum sampling rate of 65 MSPS with a differential input bandwidth of 300 MHz. The device utilizes a multistage differential pipelined architecture with output error correction logic to ensure no missing codes across the full operating temperature range. It functions on a single 3 V analog supply (2.7 V to 3.3 V) and a separate digital driver supply (2.25 V to 3.6 V). Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 58 dBc and a Spurious-Free Dynamic Range (SFDR) of 77 dBc. Power consumption is 96 mW at 65 MSPS. The component is housed in a 28-lead TSSOP package.

Feature Summary

• Features an on-chip sample-and-hold amplifier (SHA) and voltage reference for simplified system design.
• Includes a clock duty cycle stabilizer to maintain performance over wide variations in clock pulse widths.
• Supports flexible analog inputs with user-selectable ranges and offset binary or twos complement data formats.
• Provides an out-of-range signal bit to indicate overflow conditions.

Applications

• Ultrasound equipment
• IF sampling in communications receivers
• Battery-powered instruments
• Hand-held scopemeters
• Low cost digital oscilloscopes

Procurement Notes

Verify the specific suffix '65' to confirm the 65 MSPS speed grade, as the AD9215 family includes 80 MSPS and 105 MSPS variants. Ensure the ordering code matches the required package type, typically 28-TSSOP for the BRUZ designation. Confirm RoHS compliance status and check for any specific environmental certifications required by the target application before finalizing procurement.

Selection Notes

Select this model when a 65 MSPS sampling rate meets the system requirements, offering lower power consumption compared to higher-speed variants. Consider the 300 MHz analog input bandwidth for high-frequency signal acquisition. Evaluate the need for the internal reference versus external options based on noise sensitivity. Verify that the parallel digital interface and pipeline latency align with the downstream processing capabilities.

Part Context

The AD9215BRUZ-65 belongs to the AD9215 family of low-power, 10-bit ADCs manufactured by Analog Devices Inc. This family shares pin compatibility with other resolution variants, facilitating system upgrades. The device is fabricated on an advanced CMOS process and is specified for industrial temperature ranges, making it suitable for cost-sensitive and power-constrained applications requiring moderate throughput.

Replacement Considerations

Direct pin-compatible replacements within the same family include the AD9215BRU-80Z and AD9215BRU-105Z, which offer higher sampling rates but may consume more power. For different resolutions, the AD9212 or AD9214 series may be considered if pinout compatibility allows, though architectural differences require circuit re-evaluation.
