AD9002SD

Overview

The AD9002SD is an 8-bit, high-speed monolithic analog-to-digital converter (ADC) manufactured by Analog Devices Inc. Fabricated using an advanced bipolar process, this flash ADC supports sampling rates exceeding 150 megasamples per second (MSPS). The device integrates 256 parallel comparator stages with decoding logic to drive ECL-compatible output latches. It operates on a single -5.2 V supply and consumes approximately 750 mW of power. Key electrical characteristics include a maximum conversion time of 0.008 µs, a linear error of 0.39%, and an input voltage range from -6 V to 0.5 V. The component is available in a PDIP-28 package.

Feature Summary

• Sampling rate exceeds 150 MSPS
• 8-bit resolution with parallel binary output
• Single -5.2 V power supply operation
• Low input capacitance of 17 pF

Applications

• High-speed data acquisition systems
• Test and measurement instrumentation
• Wireless communication infrastructure

Part Context

The AD9002 series represents a family of high-performance flash ADCs designed for applications requiring rapid signal digitization. The 'SD' suffix typically denotes specific commercial grade or packaging variations within the broader AD9002 product line, which also includes MIL-STD-883 compliant versions. This component serves as a foundational building block for systems needing direct RF or IF sampling capabilities without intermediate down-conversion stages.

Replacement Considerations

The AD9002AD is a functionally equivalent part number within the same family, offering identical high-speed 8-bit performance specifications. When substituting, verify that the pinout compatibility remains consistent between the SD and AD suffixes, although both utilize the PDIP-28 package.
