AD9215BRU-80

Overview

The AD9215BRU-80 is a monolithic, single-supply 10-bit analog-to-digital converter operating at an 80 MSPS sampling rate. It utilizes a multistage differential pipelined architecture with output error correction logic to ensure no missing codes across the industrial temperature range of -40°C to +85°C. The device features a high-performance sample-and-hold amplifier and an internal voltage reference. It operates from 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 electrical parameters include a typical Signal-to-Noise Ratio (SNR) of 58 dBc, a Spurious-Free Dynamic Range (SFDR) of 77 dBc, and a power consumption of 104 mW at the maximum conversion rate.

Feature Summary

• Multistage differential pipelined architecture with output error correction logic for guaranteed linearity.
• Integrated wide-bandwidth differential sample-and-hold amplifier supporting flexible input configurations.
• Built-in clock duty cycle stabilizer to maintain performance under varying clock pulse widths.
• Separate digital output driver supply to accommodate various logic families.

Applications

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

Procurement Notes

Verify the specific suffix 'RU' corresponds to the 28-lead TSSOP package configuration required for your PCB layout. Confirm that the DRVDD pin is supplied within the specified 2.25 V to 3.6 V range to ensure proper digital interface compatibility. Ensure ESD precautions are observed during handling as the device is sensitive to electrostatic discharge.

Selection Notes

Select this model when a fixed 80 MSPS sampling rate is sufficient for the application bandwidth. Consider the AD9215BRU-65 if lower power consumption is prioritized over speed, or the AD9215BRU-105 if higher throughput is required. Verify that the 10-bit resolution meets the dynamic range requirements compared to higher-resolution alternatives in the same family.

Part Context

The AD9215BRU-80 belongs to the AD9215 family of low-power, 10-bit ADCs manufactured by Analog Devices. This family includes variants optimized for 65 MSPS and 105 MSPS speeds. All members share the same pinout and architectural features, allowing for design flexibility and potential upgrades within the same package footprint without redesigning the board layout.

Replacement Considerations

Pin-compatible substitutes within the same family include the AD9215BRU-65 and AD9215BRU-105. These parts offer different maximum sampling rates but maintain identical functionality and pin assignments. No external cross-manufacturer replacements are documented in the official datasheet.
