AD9218BSTZ-RL80

Overview

The AD9218BSTZ-RL80 is a dual-channel, 10-bit pipeline analog-to-digital converter manufactured by Analog Devices Inc. It supports a maximum sampling rate of 80 MSPS and operates on a single 3.0 V supply (2.7 V to 3.6 V). Each channel features an integrated track-and-hold circuit with a full-power analog bandwidth of 300 MHz. The device offers configurable differential input ranges of 1 V p-p or 2 V p-p and includes an internal voltage reference. Digital outputs are TTL/CMOS compatible and support offset binary or two's complement coding formats. It is housed in a 48-lead LQFP package and specified for industrial temperatures from -40°C to +85°C.

Feature Summary

• Dual-channel architecture with independent operation capabilities
• Integrated track-and-hold circuits and internal voltage reference
• Configurable digital output data alignment modes
• Low power consumption with dedicated single-channel power-down mode

Applications

• I and Q communications demodulation
• Hand-held oscilloscopes and battery-powered instruments
• Low-cost digital oscilloscopes
• Ultrasound equipment

Procurement Notes

Verify the specific ordering suffix RL80 against the manufacturer's official documentation to confirm packaging details. Ensure that the component meets the required environmental specifications for your application. Cross-reference the part number with the latest datasheet revision to confirm all electrical parameters remain unchanged.

Selection Notes

Select this model when a dual-channel 10-bit ADC with up to 80 MSPS throughput is required. Consider the 300 MHz analog bandwidth for direct IF sampling applications. Evaluate the pin compatibility with the 8-bit AD9288 if migrating from legacy designs. Verify that the system clock jitter requirements align with the device's aperture uncertainty specifications.

Part Context

This component belongs to the AD9218 family of high-speed, low-power analog-to-digital converters. The family includes variants supporting different maximum sampling rates, including 40 MSPS, 65 MSPS, and 105 MSPS. All variants share the same 48-lead LQFP footprint and core architecture, facilitating design flexibility across different performance tiers within the same product line.

Replacement Considerations

The AD9218BSTZ-40, AD9218BSTZ-65, and AD9218BSTZ-105 are pin-compatible alternatives within the same family. These variants offer different maximum sampling rates while maintaining identical pinouts and functional configurations.
