AD9054ABST-135

Overview

The AD9054ABST-135 is an 8-bit monolithic analog-to-digital converter optimized for high-speed, low-power applications. It features a guaranteed conversion rate of 135 MSPS and a full-power analog bandwidth of 350 MHz. The device operates on a single +5 V supply with typical power dissipation of 700 mW. It includes an internal 2.5 V reference and track-and-hold circuit, eliminating the need for external components in many designs. The part supports both single-channel and demultiplexed dual-channel output modes via TTL-compatible interfaces. It is housed in a 44-lead LQFP (ST-44) package and specified over the industrial temperature range of –40 °C to +85°C.

Feature Summary

• Integrated 2.5 V internal voltage reference and track-and-hold circuitry
• Dual-channel demultiplexed output mode for simplified high-speed digital interfacing
• TTL, CMOS, or positive-ECL compatible encode input logic
• Single +5 V power supply operation with low power consumption

Applications

• RGB Graphics Processing
• High Resolution Video
• Digital Data Storage Read Channels
• Digital Communications
• Medical Imaging

Procurement Notes

Verify the specific suffix '135' indicates the 135 MSPS speed grade when sourcing. Confirm the ST-44 plastic LQFP package option matches the design requirements. Ensure the industrial temperature range specification aligns with the operational environment. Cross-reference the ordering guide to confirm availability against the standard 200 MSPS variant.

Selection Notes

Select this model when a lower maximum sampling rate than the 200 MSPS variant is sufficient for the application. The 135 MSPS version offers cost advantages while maintaining the same 350 MHz analog bandwidth. Consider the demultiplexed output mode if the downstream digital interface cannot handle the full data rate. Verify that the 8-bit resolution meets the dynamic performance requirements for the target signal frequencies.

Part Context

This component belongs to the AD9054A family of high-speed analog-to-digital converters from Analog Devices. It shares the same architectural foundation and pinout as the AD9054ABST-200 but is characterized for a maximum conversion rate of 135 MSPS. Both variants utilize the MagAmp bit-per-stage architecture combined with flash technology to achieve high performance with low power dissipation.

Replacement Considerations

The AD9054ABST-200 is the primary functional substitute within the same package, offering a higher 200 MSPS conversion rate. No other direct cross-model replacements are documented in the official datasheet.
