AD9244BSTZRL-65

Analog To Digital Converters (ADC) Overview

The AD9244BSTZRL-65 is a monolithic, single 5 V supply, 14-bit, 65 MSPS analog-to-digital converter (ADC) featuring an on-chip high-performance sample-and-hold amplifier (SHA) and voltage reference. It utilizes a multistage differential pipelined architecture with output error correction logic to ensure 14-bit accuracy at data rates up to 65 MSPS. The device guarantees no missing codes over the full operating temperature range of –40°C to +85°C. It supports a 750 MHz analog input bandwidth and accepts a 1 V to 2 V p-p differential full-scale analog input range. Power consumption is specified at 550 mW at 65 MSPS.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm the BSTZ designation corresponds to the LQFP-48 package variant. Ensure compatibility with the required DRVDD voltage level for the target digital interface logic family before integration into the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high linearity and low power consumption in a single-supply environment. The integrated reference simplifies board layout compared to external reference solutions. Consider the 8-clock cycle pipeline latency when designing real-time signal processing paths.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9244 series, which offers pin-compatible migration from the 12-bit, 65 MSPS AD9226. The AD9244 provides enhanced resolution while maintaining similar form factors and power profiles, facilitating upgrades in existing high-speed data acquisition systems without significant redesign.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9244BSTZRL-40 serves as a lower-speed variant within the same family. Direct substitution requires verifying that the 40 MSPS maximum conversion rate meets the system's Nyquist sampling requirements.
