Product details
Overview
AD9054ABST-200 from Analog Devices is an 8-bit, 200 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 communications read channels.
For engineers reviewing the AD9054ABST-200 datasheet, AD9054ABST-200 pinout, AD9054ABST-200 application, or AD9054ABST-200 equivalent, key selection criteria include guaranteed 200 MSPS conversion rate, ±0.512 V p-p analog input range, aperture jitter of 2.3 ps rms, SNR of 45 dB at 19.7 MHz input, and ST-44 LQFP package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The AD9054ABST-200 employs Analog Devices' MagAmp bit-per-stage architecture combined with flash conversion, enabling high dynamic performance with low power consumption. Its differential analog input accepts ±0.512 V p-p signals with 36 kΩ input resistance and 4 pF capacitance, and features internal track-and-hold with 0.5 ns aperture delay and 2.3 ps rms jitter.
Timing is controlled via rising-edge–triggered ENCODE inputs; output data appears after four pipeline delays in single-channel mode (DEMUX = HIGH) or five delays in dual-channel mode (DEMUX = LOW). Digital outputs are TTL-level, with VOH ≥ 2.4 V and VOL ≤ 0.4 V under 20 mA load, and support synchronous alignment via DS/DS differential data sync inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8 bits - fixed-width binary output coding with MSB/LSB defined per DA7–DA0 and DB7–DB0 pins. |
| Max Conversion Rate | 200 MSPS - enables sampling of signals up to Nyquist frequency of 100 MHz without aliasing in baseband applications. |
| Analog Bandwidth | 350 MHz - supports accurate digitization of fast-rising presampled waveforms (e.g., video pixel transitions, imager outputs). |
| SNR @ 19.7 MHz | 45 dB - corresponds to ~7.2 effective bits; sufficient for medium-fidelity digital instrumentation and medical imaging front-ends. |
| Aperture Uncertainty | 2.3 ps rms - limits timing-induced noise floor degradation at high input frequencies (>50 MHz). |
| Power Dissipation | 781 mW typical - achieved at 5 V supply and 200 MSPS, with 128–156 mA VDD current draw. |
| Differential Nonlinearity | ±0.9 LSB (typ) - ensures monotonicity and absence of missing codes across full industrial temperature range. |
Pinout & Package
AD9054ABST-200 is housed in a 44-lead plastic thin quad flatpack (LQFP), designated ST-44, with exposed pad thermal design and surface-mount footprint compatible with industrial PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ENCODE / ENCODE | Encode clock differential pair | Rising edge of ENCODE initiates sampling; complement enables differential clock drive or single-ended biasing at VDD/3 (~1.5 V). |
| DA0–DA7 / DB0–DB7 | Dual 8-bit digital output buses | DA outputs carry even/odd samples in demux mode; DB carries interleaved data; both are TTL-compatible with 2.4 V/0.4 V logic thresholds. |
| AIN / AIN | Differential analog input terminals | Accepts ±0.512 V p-p signal centered at midscale; input impedance is 36 kΩ || 4 pF; requires ac- or dc-coupling per application. |
| VREF OUT / VREF IN | Internal reference output and input | VREF OUT supplies 2.5 V ±4% for local bypass or multi-ADC sharing; VREF IN accepts external 2.5 V ±0.25 V reference if higher accuracy required. |
| DEMUX | Output format select | LOW enables dual-channel (demux) mode (100 MSPS per port); HIGH selects single-channel mode (200 MSPS on DA only). |
| DS / DS | Data sync differential pair | Used to align output phase in demux mode; falling edge synchronizes internal pipeline; timing must meet tSDS/tHDS specs relative to ENCODE. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated track-and-hold + 2.5 V reference | Eliminates need for external driver or reference ICs in most video and instrumentation designs, reducing BOM count and layout complexity. |
| Dual-channel demultiplexed output | Reduces external interface speed requirement by 2× (e.g., 200 MSPS ADC → 100 MHz data bus), easing FPGA/CPLD capture timing closure. |
| 350 MHz analog bandwidth | Preserves fidelity of sub-nanosecond edge transitions in RGB graphics, solid-state imagers, and high-speed data storage read channels. |
| Low aperture jitter (2.3 ps rms) | Minimizes noise floor elevation at high input frequencies, sustaining >45 dB SNR up to 70 MHz input tone. |
| Single 5 V supply operation | Removes need for dual-rail or low-voltage auxiliary supplies, simplifying power delivery in embedded video and comms systems. |
Applications

FAQ
What is the maximum guaranteed sampling rate for AD9054ABST-200?
The AD9054ABST-200 is guaranteed to operate at 200 MSPS across the full industrial temperature range (–40°C to +85°C). This is validated per the Rev. D datasheet's switching performance table, where "Maximum Conversion Rate (fS)" is specified as 200 MSPS under Test Level VI conditions. Operation above this rate is not characterized or supported.
Does AD9054ABST-200 require an external reference voltage?
No, AD9054ABST-200 includes an internal 2.5 V reference with ±4% tolerance and 110 ppm/°C tempco, accessible via VREF OUT. For most video and instrumentation applications, strapping VREF OUT to VREF IN eliminates need for external reference. An external 2.5 V ±0.25 V source may be used via VREF IN if tighter accuracy or lower drift is required.
How does the DEMUX pin affect AD9054ABST-200 output behavior?
When DEMUX = HIGH, AD9054ABST-200 operates in single-channel mode: all 8-bit data appears on DA0–DA7 with four pipeline delays. When DEMUX = LOW, it enters dual-channel mode: data alternates between DA0–DA7 and DB0–DB7 with five pipeline delays, halving per-port data rate to enable 200 MSPS operation with standard TTL interfaces.
What is the analog input voltage range specification for AD9054ABST-200?
The AD9054ABST-200 accepts a differential analog input range of ±0.512 V p-p (1.024 V full-scale), referenced to AIN/AIN. The common-mode compliance range is 1.8 V to 3.2 V, allowing direct connection to op-amp drivers biased at 2.5 V. Input offset voltage is ±8 mV max over temperature, supporting accurate dc-coupled signal chains.
Is AD9054ABST-200 pin-compatible with other members of the AD9054A family?
Yes, AD9054ABST-200 shares identical ST-44 LQFP package, pinout, and electrical interface with AD9054ABST-135. Both models use the same 44-pin layout, including ENCODE/ENCODE, DA/DB buses, VREF IN/OUT, and DS/DS. No PCB redesign is needed when migrating between these variants-only firmware or clock configuration changes may be required.
