Product details
Overview
AD9203WARUZ from Analog Devices is a 10-bit, 40 MSPS automotive-qualified CMOS analog-to-digital converter with on-chip adjustable voltage reference, 74 mW power dissipation at 3 V/40 MSPS, −0.25 LSB differential nonlinearity, and 9.55 ENOB at 20 MHz input - used in high-speed video signal digitization and IF undersampling up to 130 MHz.
For engineers reviewing the AD9203WARUZ datasheet, AD9203WARUZ pinout, AD9203WARUZ application, or AD9203WARUZ equivalent, key selection factors include its TSSOP-28 automotive qualification, programmable power-down (0.65 mW), differential/single-ended 1–2 Vp-p input range, and out-of-range (OTR) flag for real-time signal integrity monitoring.
Technical Context
The AD9203WARUZ implements a multistage differential pipeline architecture guaranteeing no missing codes across −40°C to +85°C. It supports straight binary or twos-complement output via DFS pin control and uses a single clock input to synchronize conversion cycles with 5.5-clock-cycle latency.
Its internal clamp circuit enables DC restoration of video signals, while the PWRCON pin allows external resistor-based power scaling at reduced sample rates - delivering 17 mW at 5 MSPS with 9.7 ENOB. Input bandwidth reaches 390 MHz (−3 dB), supporting IF sampling up to 130 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - delivers 1024 discrete amplitude levels for medium-fidelity signal capture in automotive vision and radar front ends. |
| Max Sample Rate | 40 MSPS - supports Nyquist-limited baseband digitization up to 20 MHz or IF undersampling of RF bands. |
| DNL | ±0.25 LSB (typ) - ensures monotonicity and minimal code-width variation critical for measurement accuracy. |
| ENOB @ 20 MHz | 9.55 bits - reflects effective dynamic resolution after noise and distortion, enabling >57 dB SINAD in wideband applications. |
| Power @ 40 MSPS | 74 mW at 3 V - enables low-thermal-load integration in space-constrained automotive ECUs and ADAS modules. |
| Input Range | 1 V to 2 Vp-p differential or single-ended - configurable gain staging without external amplification. |
| Standby Power | 0.65 mW - reduces system-level quiescent current during idle intervals in battery-sensitive modules. |
Pinout & Package
AD9203WARUZ is housed in a 28-lead TSSOP (RU-28) package per JEDEC MO-153-AE, with 0.65 mm pitch, 9.7 mm × 4.4 mm body, and coplanarity ≤0.10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DRVSS) | Digital Ground | Reference return for digital supply and output drivers; must be isolated from AVSS to minimize digital noise coupling. |
| 15 (CLK) | Master Sampling Clock Input | Edge-triggered timing source controlling all pipeline stages; requires 25 ns minimum period (40 MSPS max). |
| 13 (OTR) | Out-of-Range Indicator | Active-high flag signaling ADC saturation; used with D9 to distinguish over- vs. underrange conditions. |
| 17 (STBY) | Power-Down Control | HI asserts standby mode (0.65 mW); LO enables full operation - supports rapid wake-up in event-driven systems. |
| 25–26 (AINP/AINN) | Differential Analog Input | High-impedance, 1.4 pF input capacitance nodes accepting 1–2 Vp-p differential signals with 390 MHz bandwidth. |
| 23 (VREF) | Reference In/Out | Configurable 0.5 V or 1 V output (via REFSENSE); also accepts external reference for improved dc accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive Qualification | Qualified per AEC-Q100 Grade 2 (−40°C to +85°C); controlled manufacturing and reliability reporting for ADAS and infotainment systems. |
| Programmable Power Scaling | External resistor on PWRCON reduces current draw at sub-40 MSPS rates - e.g., 17 mW at 5 MSPS preserves ENOB without sacrificing accuracy. |
| Integrated Clamp Circuit | CLAMP/CLAMPIN pins enable DC restoration of video waveforms - eliminates need for external AC-coupling and baseline correction circuits. |
| Dual Output Format | DFS pin selects straight binary (default) or twos-complement output - simplifies interface with FPGA logic or DSP data paths. |
| Out-of-Range Detection | OTR signal flags overflow/underflow independently of MSB - enables real-time signal health monitoring without post-processing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9215BRUZ | 12-bit, 80 MSPS, 125 mW at 3 V; no integrated clamp; wider input bandwidth (500 MHz). | Higher resolution and speed suit demanding radar or software-defined radio; lacks DC restoration for video. | Select when ENOB >10 bits and IF >130 MHz are required; verify layout supports higher power and noise isolation. |
| MAX1186ETL+ | 10-bit, 40 MSPS, 65 mW; 24-pin TQFN; no OTR flag; fixed 1.25 V reference only. | Smaller footprint and lower power, but no out-of-range indicator or adjustable reference - limits diagnostic capability. | Prefer for space-constrained consumer-grade video where automotive qualification and signal health monitoring are not mandatory. |
Compared with AD9203WARUZ, AD9215BRUZ offers higher resolution and speed at increased power and complexity, while MAX1186ETL+ trades diagnostics and flexibility for compactness and marginal power savings - making AD9203WARUZ optimal for automotive video and IF sampling where clamp, OTR, and AEC-Q100 compliance are essential.

FAQ
What is the operating temperature range specified for the AD9203WARUZ?
The AD9203WARUZ is rated for −40°C to +85°C and qualified per AEC-Q100 Grade 2 for automotive use. This range is validated across all electrical specifications including ENOB, DNL, and power consumption - ensuring reliable operation in engine bay and cabin environments without derating.
Does the AD9203WARUZ support both differential and single-ended analog inputs?
Yes, the AD9203WARUZ accepts either differential (AINP/AINN) or single-ended analog inputs with a configurable 1 V to 2 Vp-p range. The input structure maintains 1.4 pF capacitance and 390 MHz bandwidth in both modes, and dc common-mode level is internally biased for seamless mode switching.
How does the power-down mode function on the AD9203WARUZ?
The AD9203WARUZ enters standby mode when STBY pin is driven HIGH, reducing power consumption to 0.65 mW. Wake-up time is under 100 ns, and full performance resumes within one clock cycle - enabling rapid response in motion-triggered automotive sensing applications.
Can the AD9203WARUZ be used with an external voltage reference?
Yes, the AD9203WARUZ supports external reference input via the VREF pin when REFSENSE is tied to AVSS. This bypasses the internal 1 V or 0.5 V reference and allows use of precision external references to improve dc accuracy and temperature drift performance in metrology-grade designs.
What packaging and RoHS compliance status does the AD9203WARUZ have?
The AD9203WARUZ is supplied in a 28-lead TSSOP (RU-28) package and is RoHS compliant (indicated by the "Z" suffix). Its JEDEC MO-153-AE footprint features 0.65 mm pitch, 9.7 mm × 4.4 mm body size, and meets lead-free reflow profile requirements up to 260°C peak.
