Overview
The AD9218BST-RL40 is a dual-channel, 10-bit monolithic sampling analog-to-digital converter manufactured by Analog Devices Inc. It features an internal track-and-hold circuit and operates at a maximum sampling rate of 40 MSPS. The device utilizes a single 3.0 V power supply (ranging from 2.7 V to 3.6 V) and consumes approximately 275 mW per channel at full speed. It offers a 300 MHz analog bandwidth and supports both offset binary and two's complement digital output formats. The component is housed in a 48-lead LQFP package and is specified for industrial operating temperatures between -40°C and +85°C.
Feature Summary
- Dual-channel architecture with independent operation capabilities
- Integrated on-chip voltage reference and track-and-hold circuits
- TTL/CMOS compatible digital outputs with selectable data formats
- Low power consumption suitable for battery-powered applications
Applications
- Battery-powered instruments
- Hand-held scopemeters
- Low cost digital oscilloscopes
- I and Q communications systems
- Ultrasound equipment
Procurement Notes
Verify the specific ordering suffix RL40 against official documentation to confirm tape-and-reel packaging and the 40 MSPS speed grade. Ensure that the required environmental specifications align with the industrial temperature range limits defined in the datasheet. Cross-reference pin configurations with existing PCB layouts to guarantee compatibility during integration.
Selection Notes
Select this model when a low-cost, dual-channel solution with moderate sampling rates is required. It serves as a direct pin-compatible upgrade path from the 8-bit AD9288, facilitating system migration without redesigning the printed circuit board. Consider its performance characteristics for applications requiring direct intermediate frequency sampling to simplify analog front-end designs.
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 speeds, including 65 MSPS, 80 MSPS, and 105 MSPS. All members share identical pinouts and core architectural features, allowing for flexible design scaling based on bandwidth requirements.
Replacement Considerations
The AD9218BSTZ-40 is a verified equivalent part number within the same product family. Both components offer identical electrical specifications and pin configurations, ensuring functional interchangeability in existing designs.
