AD9054ABSTZ-135

Analog To Digital Converters (ADC) Overview

The AD9054ABSTZ-135 is an 8-bit monolithic analog-to-digital converter optimized for high speed and low power. 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, accepting TTL, CMOS, or positive-ECL logic inputs. Digital outputs are available in single-channel (Channel A) or dual-channel demultiplexed modes via a 44-lead LQFP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix -135 confirms the 135 MSPS speed grade rather than the standard 200 MSPS variant. Confirm the ST-44 package option matches the required surface mount footprint. Ensure ESD precautions are observed during handling due to sensitivity. Check RoHS compliance status for the specific manufacturing batch.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a guaranteed 135 MSPS sampling rate is sufficient, offering a cost advantage over the 200 MSPS version. Use the dual-channel mode if the downstream digital interface cannot handle the full 135 MHz data rate. Ensure the system clock jitter remains below 10 ps at 100 MHz for optimal dynamic performance. Verify that the 1 V p-p input range aligns with the source signal amplitude.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9054A family of high-speed ADCs from Analog Devices. It utilizes a patented MagAmp bit-per-stage architecture combined with flash converter technology. The family includes variants with different speed grades, such as the 200 MSPS AD9054ABST-200, sharing the same 8-bit resolution and 44-lead LQFP packaging.
