Product details
Overview
AD9054ABST-135 from Analog Devices is an 8-bit, 135 MSPS monolithic analog-to-digital converter with 350 MHz full-power analog bandwidth, internal 2.5 V reference, and track-and-hold circuitry. It operates on a single 5 V supply, delivers TTL-compatible digital outputs, and supports dual-channel (demultiplexed) or single-channel output modes for high-speed video digitization and data acquisition systems.
For engineers reviewing the AD9054ABST-135 datasheet, AD9054ABST-135 pinout, AD9054ABST-135 application, or AD9054ABST-135 equivalent, this page provides verified specifications, package mapping to ST-44 LQFP, functional pin definitions, real-world use cases in RGB graphics and medical imaging, and two validated alternative parts with documented technical and application differences.
Technical Context
The AD9054ABST-135 employs a MagAmp bit-per-stage architecture combined with flash conversion to achieve low power (600 mW typical) and high dynamic performance. Its differential analog input accepts ±512 mV p-p signals with 36 kΩ input resistance and 4 pF capacitance, and features aperture uncertainty of 2.3 ps rms at 25°C.
Timing is governed by a rising-edge–triggered ENCODE input with 2.0–22 ns pulsewidth tolerance; demultiplexed mode introduces five pipeline delays, while single-channel mode uses four. The DEMUX pin selects between interleaved dual-port (DEMUX = LOW) and single-port (DEMUX = HIGH) output configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8 bits - fixed-width binary output with MSB/LSB alignment per DA7–DA0 and DB7–DB0 pins. |
| Max Conversion Rate | 135 MSPS - guaranteed maximum sampling rate for full-spec operation over –40°C to +85°C. |
| Analog Bandwidth | 350 MHz - full-power 3 dB bandwidth enabling accurate digitization of fast-rising video and imaging waveforms. |
| Input Voltage Range | ±512 mV p-p - defines full-scale differential input swing referenced to AIN/AIN; supports ac- or dc-coupled signal paths. |
| Power Dissipation | 600 mW typical - measured at fS = 135 MSPS, –1 dBFS input at 19.7 MHz; enables thermal management in dense PCB layouts. |
| SNR @ 19.7 MHz | 42–45 dB - signal-to-noise ratio range reflects production test limits; usable for >7-bit effective resolution in baseband applications. |
| Reference Output | 2.4–2.6 V - internally generated 2.5 V reference with 110 ppm/°C tempco; can drive multiple ADCs or external circuitry up to several mA. |
Pinout & Package
AD9054ABST-135 is housed in a 44-lead LQFP surface-mount package (ST-44), measuring 10 mm × 10 mm × 1.4 mm, with exposed pad for thermal enhancement and rated for industrial temperature range (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ENCODE / ENCODE | Encode clock inputs (differential pair) | Rising edge of ENCODE initiates sampling; complement input enables differential clocking or single-ended bias via internal 1.5 V divider. |
| DA0–DA7 / DB0–DB7 | Digital output banks (Channel A and B) | DA7–DA0 carry even/odd samples in demux mode; DB7–DB0 carry interleaved data; both are TTL-compatible, 3-state disabled when unused. |
| DEMUX | Output format select | LOW enables dual-channel demultiplexed output (135 MSPS → 67.5 MSPS per port); HIGH selects single-channel mode (all data on DA0–DA7). |
| DS / DS | Data sync control (differential) | Falling edge aligns output phase in dual-channel mode; required once at power-up or periodically to resolve port ambiguity. |
| VREF OUT / VREF IN | Internal reference output and input | VREF OUT supplies 2.5 V ±0.1 V; strapping to VREF IN enables self-referenced operation; external 2.5 V ±0.25 V sources supported. |
| AIN / AIN | Differential analog input terminals | Accepts ±512 mV p-p signal; common-mode voltage fixed at 2.5 V when using internal reference; input impedance 36 kΩ || 4 pF. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated track-and-hold | Eliminates need for external THA; supports 350 MHz full-power bandwidth and sub-nanosecond slew handling in graphics digitization. |
| Dual-output demultiplexing | Reduces digital interface speed requirement by 2× (e.g., 135 MSPS → 67.5 MSPS per port), easing FPGA/CPLD timing closure. |
| Single 5 V supply operation | Removes need for dual-rail or precision analog supplies; simplifies board power architecture and reduces BOM count. |
| On-chip 2.5 V reference | Provides stable, low-drift reference (110 ppm/°C) with ±4% initial accuracy; eliminates external reference IC and associated layout sensitivity. |
| TTL-compatible digital outputs | Direct interface to 5 V logic families without level-shifting; VOH ≥ 2.4 V, VOL ≤ 0.4 V under 20 mA load ensures noise margin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9054ABST-200 | Same ST-44 package and pinout; higher guaranteed max conversion rate (200 MSPS) and identical analog bandwidth (350 MHz); higher power (700 mW typ). | Required for systems needing >135 MSPS sampling (e.g., 4K video line rates); otherwise functionally interchangeable in 135 MSPS designs. | Select AD9054ABST-200 only if full 200 MSPS capability is needed; AD9054ABST-135 offers cost and power advantage where 135 MSPS suffices. |
| ADS5271IPFP | 10-bit, 65 MSPS, 64-pin HTQFP; no integrated T/H or reference; requires external clock conditioning and reference source. | Targets lower-speed, higher-resolution applications (e.g., MRI signal chains); lacks demux mode and single-supply simplicity. | Choose ADS5271IPFP only when >8-bit resolution is mandatory and system can accommodate external support components and layout complexity. |
Compared with AD9054ABST-200, the AD9054ABST-135 trades 65 MSPS of headroom for lower power and cost, while retaining identical analog performance and pin compatibility; versus ADS5271IPFP, it sacrifices resolution for integration, ease of use, and higher throughput in bandwidth-constrained systems.

FAQ
What is the guaranteed maximum sampling rate for AD9054ABST-135?
The AD9054ABST-135 is guaranteed to operate at up to 135 MSPS across the full industrial temperature range (–40°C to +85°C). This is explicitly specified in the Electrical Characteristics table under "Maximum Conversion Rate (fS)" with "Full" temperature range and "VI" test level, confirming production validation at this rate. Performance above 135 MSPS is not guaranteed for this variant.
Does AD9054ABST-135 require an external reference voltage?
No, AD9054ABST-135 does not require an external reference voltage. It integrates a 2.5 V reference with 110 ppm/°C temperature coefficient and 2.4–2.6 V output range. The VREF OUT pin can be directly connected to VREF IN for self-referenced operation, eliminating external reference components in most applications.
How does the DEMUX pin affect output behavior in AD9054ABST-135?
In AD9054ABST-135, the DEMUX pin controls output configuration: when pulled LOW, it enables dual-channel demultiplexed mode, alternating samples between DA0–DA7 and DB0–DB7 at half the encode rate; when HIGH, all data appears on DA0–DA7 only. This selection is static and determines pipeline depth (five vs. four delays) and port utilization.
What is the analog input impedance of AD9054ABST-135?
The AD9054ABST-135 has a differential analog input impedance of 36 kΩ in parallel with 4 pF, measured at 25°C. This value is confirmed in the "Analog Input" section of the Electrical Characteristics table under "Input Resistance" and "Input Capacitance", and remains stable across the full industrial temperature range.
Can AD9054ABST-135 operate with a 3.3 V digital interface?
No, AD9054ABST-135 cannot reliably interface with 3.3 V logic. Its digital outputs are TTL-compatible with VOH ≥ 2.4 V and VOL ≤ 0.4 V under 20 mA load, but it requires a 5 V supply (VDD = 5 V) and produces output levels referenced to that rail. Driving 3.3 V inputs would require level-shifting circuitry to avoid overvoltage or logic threshold violations.
