AD9215BRUZ-80

Overview

The AD9215BRUZ-80 is a monolithic, single 3 V supply, 10-bit analog-to-digital converter (ADC) operating at an 80 MSPS sampling rate. It features a differential input with a 300 MHz bandwidth and utilizes a multistage differential pipelined architecture with output error correction logic to guarantee no missing codes over the full industrial temperature range of −40°C to +85°C. The device includes an on-chip reference and sample-and-hold amplifier, supporting flexible analog input ranges from 1 V p-p to 2 V p-p. Power consumption is 104 mW at 80 MSPS, with a signal-to-noise ratio of 58 dBc and spurious-free dynamic range of 77 dBc.

Feature Summary

• Multistage differential pipelined architecture with digital output error correction logic for high accuracy
• Wide bandwidth truly differential sample-and-hold amplifier configurable for single-ended or differential operation
• Integrated clock duty cycle stabilizer to maintain performance across wide variations in clock pulse widths
• Single 3 V analog supply with separate digital driver supply accommodating 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 ordering suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements, specifically the 2.7 V to 3.3 V analog supply and 2.25 V to 3.6 V digital supply rails. Confirm that the 28-TSSOP package dimensions align with the PCB footprint design constraints.

Selection Notes

Select this component when a low-power, 10-bit resolution is required at 80 MSPS data rates. Consider the internal reference capability if external precision references are undesirable. Evaluate the 300 MHz analog input bandwidth against the maximum frequency of the input signal to ensure adequate aperture jitter performance and signal fidelity.

Part Context

This part belongs to the AD9215 family of low-power ADCs, which also includes variants operating at 65 MSPS and 105 MSPS. The family shares similar architectural features and pinouts, facilitating potential upgrades to higher speeds or different resolutions within the same product line while maintaining system compatibility.

Replacement Considerations

Direct pin-compatible replacements within the AD9215 family include the AD9215BRU-65 and AD9215BRU-105. Verify that the alternative speed variant meets the specific timing requirements of the application before substitution.
