AD9430BSV-210

Analog To Digital Converters (ADC) Overview

The AD9430BSV-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. Digital outputs are available in TTL/CMOS or LVDS formats, supporting offset binary or two's complement coding. Key specifications include a typical SNR of 65 dB at 70 MHz input, DNL of ±0.3 LSB, and INL of ±0.5 LSB. It is housed in a 100-lead TQFP package rated for -40°C to +85°C.

• Dual output data options including demultiplexed CMOS and LVDS modes
• On-chip track-and-hold and scalable voltage reference
• Data sync input and data clock output for timing alignment
• Clock duty cycle stabilizer for improved jitter performance

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 'BSV' against the manufacturer's current ordering guide to confirm pinout compatibility and package variations. Confirm RoHS compliance status and lead times directly with Analog Devices or authorized distributors, as availability may vary by region. Ensure proper ESD handling procedures are followed during storage and installation due to the sensitivity of the BiCMOS process.

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. Consider the LVDS interface if interfacing with modern FPGA technology to reduce noise and simplify routing. Verify that the system can accommodate the 1.3 W typical power dissipation and provide adequate thermal management via the exposed heat slug. Ensure the input signal range matches the selected full-scale setting via the S5 pin configuration.

Analog To Digital Converters (ADC) Part Context

The AD9430 series includes variants operating at 170 MSPS and 210 MSPS. The AD9430BSV-210 specifically denotes the 210 MSPS grade within the 12-bit pipeline ADC family. It shares architectural similarities with other high-speed converters from Analog Devices but is distinct in its specific speed grade and interface options. The device is designed to replace older generation ADCs while offering improved dynamic performance and lower power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9430 is pin-compatible with the 10-bit AD9411 in LVDS mode only. For direct replacement, verify that the application can tolerate the difference in resolution. Other potential substitutes within the Analog Devices portfolio include the AD9626 or AD9639 series, though these may require significant schematic and layout modifications due to differences in interface protocols and pinouts.
