AD9430BSVZ-210

Analog To Digital Converters (ADC) Overview

The AD9430BSVZ-210 is a 12-bit, monolithic sampling analog-to-digital converter (ADC) optimized for high performance and low power. It operates at a maximum conversion rate of 210 MSPS with a 700 MHz full-power analog bandwidth. The device features an on-chip track-and-hold circuit and reference, requiring only a single 3.3 V supply. It offers two output data options: demultiplexed 3.3 V CMOS outputs at 105 MSPS or LVDS outputs at 210 MSPS. Key dynamic specifications include a Signal-to-Noise Ratio (SNR) of 65 dB and an Effective Number of Bits (ENOB) of 10.6 bits at a 70 MHz input frequency. Typical power dissipation is 1.3 W at the rated speed.

Analog To Digital Converters (ADC) Feature Summary

• Integrated track-and-hold and voltage reference simplify system design by providing a complete conversion solution.
• Dual-mode digital interface supports both demultiplexed CMOS and LVDS outputs to accommodate various FPGA technologies.
• Includes a clock duty cycle stabilizer and data sync input for precise timing alignment in CMOS mode.
• Features an out-of-range (OR) output bit to indicate when the input signal exceeds the selected range.

Analog To Digital Converters (ADC) Applications

• Wireless and wired broadband communications
• Cable reverse path systems
• Communications test equipment
• Radar and satellite subsystems
• Power amplifier linearization

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '210' to confirm the 210 MSPS operating grade, as the AD9430 family also includes a 170 MSPS variant. Ensure the ordering code matches the required package type, which is a 100-lead TQFP. Confirm that the application environment falls within the specified industrial temperature range of -40°C to +85°C. Check for RoHS compliance status if required by local regulations. Validate that the board layout accommodates the exposed thermal pad for adequate heat dissipation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 210 MSPS sampling rate are required for wideband applications. Choose the LVDS output mode for direct interfacing with modern FPGAs at full speed, or use CMOS mode for lower-speed demultiplexed data processing. Consider the 1.5 V differential input voltage range and internal reference capabilities when designing the analog front end. Evaluate the 1.3 W typical power consumption against thermal constraints in the final enclosure design.

Analog To Digital Converters (ADC) Part Context

The AD9430 belongs to Analog Devices' high-performance pipeline ADC family designed for broadband systems. It is fabricated using an advanced BiCMOS process to achieve low power and high linearity. The device is pin-compatible with the 10-bit AD9411 in LVDS mode only, allowing for potential design upgrades without changing the footprint. It serves as a bridge between mid-resolution and high-resolution ADC markets, offering a balance of speed and accuracy.
