Product details
Overview
AD9220ARSZ from Analog Devices is a monolithic 12-bit analog-to-digital converter with 10.0 MSPS sampling rate, 70 dB SINAD, and 88 dB SFDR, operating on single 5 V analog supply and 2.7–5.25 V digital supply. It integrates a low-noise sample-and-hold amplifier and programmable 1 V/2.5 V voltage reference, and is used in high-speed data acquisition systems requiring precise digitization of baseband or IF signals.
For engineers reviewing the AD9220ARSZ datasheet, AD9220ARSZ pinout, AD9220ARSZ application, or AD9220ARSZ equivalent, this page delivers verified technical context, exact pin functions, real-world application mappings, and two validated alternative parts for design flexibility in communications, medical imaging, and test equipment.
Technical Context
The AD9220ARSZ employs a four-stage differential pipelined architecture with digital error correction logic to guarantee no missing codes over temperature and deliver true 12-bit linearity (±0.5 LSB INL max, ±0.3 LSB DNL max). Its sample-and-hold amplifier supports both single-ended and differential input configurations with flexible common-mode voltage control via VINA/VINB and SENSE pin selection.
Internal timing uses clock rising edge for sampling and clock high/low phases to control track/hold states. Pipeline latency is fixed at three clock cycles, and output data is straight binary with OTR overflow flag. The device achieves 60 MHz full-power bandwidth and 4 ps rms aperture jitter, enabling Direct-IF downconversion applications up to Nyquist frequency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit guaranteed, with no missing codes across –40°C to +85°C operation. |
| Max Conversion Rate | 10.0 MSPS - enables real-time digitization of wideband IF signals up to 5 MHz input frequency. |
| SINAD / ENOB | 70 dB / 11.3 bits at 100 kHz input - ensures high-fidelity signal reconstruction in precision measurement. |
| SFDR | 88 dB typ at 100 kHz - suppresses spurious tones critical for spectral purity in communications receivers. |
| Input Referred Noise | 0.09 LSB rms (VREF = 2.5 V) - corresponds to ~115 µV rms noise floor for 5 V p-p input span. |
| Power Consumption | 254 mW typ (59 mW for AD9221, 100 mW for AD9223) - scales with speed, enabling thermal-aware system partitioning. |
| Analog Input Range | Configurable 2 V p-p (VREF = 1 V) or 5 V p-p (VREF = 2.5 V), supporting both single-ended and differential interfaces. |
Pinout & Package
AD9220ARSZ is housed in a 28-lead SSOP (Shrink Small Outline Package) with 0.635 mm lead pitch and exposed pad for thermal management. Package dimensions: 10.2 mm × 5.3 mm × 1.75 mm (max height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Clock input | Rising-edge-triggered master clock; minimum pulse width 45 ns; supports up to 10 MSPS with 100 ns period. |
| VINA / VINB | Differential analog inputs | Voltage difference (VINA – VINB) defines core ADC input; supports dc-coupled single-ended or ac-coupled differential modes. |
| VREF | Reference I/O | Configurable 1 V or 2.5 V internal reference output; also accepts external reference for improved drift performance. |
| SENSE | Reference select | Logic-high selects 2.5 V mode; logic-low selects 1 V mode - sets full-scale input span and gain calibration. |
| OTR | Out-of-range indicator | Active-high flag signaling overflow; used with MSB to distinguish high vs. low saturation conditions. |
| BIT 1–BIT 12 | Digital output bus | Straight binary format, MSB (BIT 1) to LSB (BIT 12); outputs latched on clock rising edge with 8–19 ns delay. |
| AVDD / AVSS | Analog power / ground | 5 V ±5% analog supply pair; separate from digital domain to minimize noise coupling into conversion path. |
| DVDD / DVSS | Digital power / ground | 2.7–5.25 V digital supply; supports 3.3 V or 5 V logic interfacing without level shifters. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip sample-and-hold amplifier | Enables direct connection to multiplexed sensor arrays or RF front-ends without external buffering; 60 MHz full-power bandwidth. |
| Programmable internal voltage reference | Reduces BOM count by eliminating external reference ICs; selectable 1 V or 2.5 V output with ±35 mV tolerance at 2.5 V mode. |
| Differential input architecture | Rejects common-mode noise and distortion; allows flexible biasing (e.g., 2.5 V common-mode) for single-supply systems. |
| Low aperture jitter (4 ps rms) | Preserves SNR at high input frequencies; critical for undersampling and IF sampling applications beyond baseband. |
| Three-cycle pipeline latency | Predictable timing behavior simplifies synchronization in FPGA-based data capture engines and real-time DSP pipelines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit, 10 MSPS ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9220ARZ | Same die, but in 28-lead SOIC package (JA = 71.4°C/W vs. SSOP's 63.3°C/W); identical electrical specs and pinout. | Preferred where board space permits larger footprint and thermal mass improves long-term stability in ambient >70°C environments. | Select AD9220ARZ when mechanical robustness and solder-joint reliability outweigh compactness requirements. |
| ADS8325IPFBT | 16-bit, 100 kSPS SAR ADC (TI); higher resolution but 100× slower; no on-chip reference or SHA; requires external driver. | Suitable only for low-speed precision DC measurements (e.g., strain gauge bridges), not for AC or IF sampling. | Choose ADS8325IPFBT only if resolution >12 bits is mandatory and throughput ≤100 kSPS is acceptable. |
Compared with AD9220ARSZ, AD9220ARZ offers identical performance in a thermally heavier SOIC package, while ADS8325IPFBT trades speed and integration for raw resolution-making AD9220ARSZ the sole fit for 10 MSPS, self-contained, mixed-signal IF/data acquisition roles.

FAQ
What is the maximum sampling rate supported by the AD9220ARSZ?
The AD9220ARSZ supports a maximum conversion rate of 10.0 MSPS, as specified in its datasheet under all operating conditions from –40°C to +85°C. This rate is enabled by its optimized pipelined architecture and is validated with 70 dB SINAD and 88 dB SFDR at low input frequencies. Exceeding 10 MSPS degrades dynamic performance and violates guaranteed specifications for AD9220ARSZ.
Does the AD9220ARSZ require an external voltage reference?
No, the AD9220ARSZ does not require an external voltage reference because it integrates a programmable internal reference delivering either 1 V or 2.5 V, selected via the SENSE pin. However, an external reference can be applied to the VREF pin to improve temperature drift and long-term stability when system-level accuracy exceeds internal reference specifications.
Can the AD9220ARSZ operate with a 3.3 V digital supply?
Yes, the AD9220ARSZ supports DVDD from 2.7 V to 5.25 V, making it fully compatible with 3.3 V digital logic families. Its digital outputs meet VOH ≥ 2.80 V and VOL ≤ 0.4 V at IOH = 0.5 mA and IOL = 1.6 mA respectively under 3.3 V DVDD, enabling direct interface to FPGAs and microcontrollers without level-shifting circuitry.
What is the function of the OTR pin on the AD9220ARSZ?
The OTR (Out-of-Range) pin on the AD9220ARSZ is an active-high indicator that signals when the analog input exceeds the valid full-scale range. When asserted, OTR works with the MSB to distinguish between high overflow (MSB = 1, OTR = 1) and low overflow (MSB = 0, OTR = 1), enabling robust saturation handling in real-time signal processing firmware for AD9220ARSZ-based systems.
How does the AD9220ARSZ handle differential versus single-ended analog inputs?
The AD9220ARSZ accepts both differential (VINA – VINB) and single-ended inputs via the same pins. In differential mode, common-mode voltage is set by biasing VINB (e.g., to 2.5 V), while in single-ended mode, VINB is tied to a fixed reference (e.g., VREF/2). The SENSE pin configures internal gain, and the SHA topology inherently rejects common-mode noise - a key capability confirmed in AD9220ARSZ's THD vs. frequency plots.
