AD9054ABST-200

Overview

The AD9054ABST-200 is an 8-bit monolithic analog-to-digital converter optimized for high speed and low power. It features a guaranteed conversion rate of 200 MSPS and a full-power analog bandwidth of 350 MHz. The device operates on a single +5 V supply with typical power dissipation of 781 mW. It includes an internal 2.5 V reference and track-and-hold circuit, eliminating the need for external components in many applications. The part uses TTL output interface logic and is available in single or demultiplexed output ports. It is fabricated using an advanced BiCMOS process and housed in a 44-lead LQFP plastic package (ST-44).

Feature Summary

• Utilizes MagAmp bit-per-stage architecture combined with flash converter technology for high performance.
• Supports dual-channel interleaved operation to reduce external digital interface speed requirements.
• Integrates internal voltage reference and track-and-hold circuitry for simplified system design.

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm the maximum sampling rate specification. The AD9054ABST-200 variant guarantees a 200 MSPS conversion rate, whereas the AD9054ABST-135 variant is limited to 135 MSPS. Ensure the procurement order matches the required throughput specifications for the target application design.

Selection Notes

Select this component when high dynamic performance and wide analog bandwidth are required alongside low power consumption. The device supports both single-ended and differential encode clock inputs. Consider the demultiplexed output mode if the downstream digital logic cannot handle the full 200 MSPS data rate, as it halves the output port frequency while maintaining the internal conversion speed.

Part Context

This component belongs to the AD9054A family of 8-bit, 200 MSPS A/D converters manufactured by Analog Devices Inc. The family utilizes a patented folding-bit architecture to achieve reduced power consumption and die size compared to traditional flash converters. The ST-44 package option provides a space-saving surface mount solution suitable for dense PCB layouts.

Replacement Considerations

The AD9054ABST-135 is a lower-cost version within the same family but is restricted to a 135 MSPS maximum conversion rate. No other direct pin-compatible replacements are documented in the provided datasheet.
