Overview
The AD9218BSTZ-RL65 is a dual-channel, 10-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 65 MSPS. It features a pipeline architecture with on-chip track-and-hold circuits and an internal voltage reference. The device supports differential or single-ended inputs with selectable 1 V p-p or 2 V p-p ranges. Digital outputs are TTL/CMOS compatible, offering user-selectable offset binary or two's complement formats. Powered by a single 3.0 V supply (2.7 V to 3.6 V), it dissipates approximately 340 mW per channel at full speed. The component is housed in a 48-lead LQFP package and operates within the industrial temperature range of -40°C to +85°C.
Feature Summary
- Dual-channel monolithic design with independent operation capabilities
- Integrated track-and-hold circuitry and internal voltage reference
- Configurable digital output coding and data alignment modes
- Low power consumption with single-channel power-down functionality
Applications
- Battery-powered instruments
- Hand-held scopemeters
- Low cost digital oscilloscopes
- I and Q communications systems
- Ultrasound equipment
Procurement Notes
Verify that the ordering suffix RL65 corresponds to the 65 MSPS speed grade as specified in the official Analog Devices datasheet. Confirm the package type is the 48-lead LQFP and check for RoHS compliance status. Ensure the supplier provides valid traceability documentation for the specific manufacturing lot.
Selection Notes
Select this model when a 65 MSPS sampling rate is required for dual-channel applications. It serves as a pin-compatible upgrade path from the 8-bit AD9288, facilitating migration to higher resolution without PCB redesign. Consider the 300 MHz analog bandwidth and low crosstalk characteristics for high-frequency signal processing needs.
Part Context
This component belongs to the AD9218 family of dual 10-bit ADCs, which includes variants rated for 40, 80, and 105 MSPS. The BSTZ-RL65 designation indicates the surface-mount LQFP package and the specific 65 MSPS performance grade. It shares architectural similarities with other high-speed converters in the Analog Devices portfolio designed for direct IF sampling.
Replacement Considerations
The AD9218BSTZ-40, AD9218BSTZ-80, and AD9218BSTZ-105 are pin-compatible alternatives within the same series. These variants offer different maximum sampling rates but maintain identical packaging and functional interfaces.
