AD9480ASUZ-250

Analog To Digital Converters (ADC) Overview

The AD9480ASUZ-250 is an 8-bit, monolithic analog-to-digital converter (ADC) optimized for high-speed and low-power applications. It operates at a maximum conversion rate of 250 MSPS with a single 3.3 V supply. The device features a differential input range of 1 V p-p and includes an internal 1.0 V reference. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 47 dB at 19.7 MHz input frequency and a Differential Nonlinearity (DNL) of ±0.85 LSB. Power dissipation is 590 mW at full speed, reducible to 15 mW in power-down mode. It utilizes LVDS outputs and is housed in a 44-lead TQFP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrated track-and-hold circuit and internal voltage reference eliminate the need for external driver components.
• LVDS digital outputs simplify timing requirements and improve noise immunity.
• Internal clock duty-cycle stabilizer optimizes sampling timing across a wide range of input duty cycles.
• Power-down mode significantly reduces total consumption when the device is not actively converting.

Analog To Digital Converters (ADC) Applications

• Digital oscilloscopes
• Instrumentation and measurement systems
• Communications infrastructure
• Point-to-point radios

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix ASUZ against the manufacturer's current ordering guide to confirm package type and temperature grade. Ensure that the required DNL specification matches the ASUZ variant limits rather than the BSUZ variant. Confirm availability through authorized distributors as stock levels fluctuate. Check for RoHS compliance documentation prior to final procurement decisions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution at 250 MSPS is sufficient for the application bandwidth. Consider the 1 V p-p input range and ensure the signal chain provides appropriate gain or attenuation. Verify that the system can accommodate LVDS signaling standards. Evaluate the power budget against the 590 mW active consumption requirement.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9480 series of high-speed ADCs from Analog Devices. It is designed for applications requiring moderate resolution with high sampling rates. The device competes in the market segment for mid-range data acquisition systems where power efficiency and ease of integration are prioritized over ultra-high resolution.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the AD9480BSUZ-250, which offers tighter linearity specifications. Other series members like the AD9230 or AD9250 offer higher resolutions but require different interface protocols such as JESD204B.
