Product details
Overview
AD9220ARSZ-REEL from Analog Devices is a monolithic 12-bit, 10 MSPS analog-to-digital converter with on-chip sample-and-hold amplifier and programmable 2.5 V/1 V reference, operating from a single 5 V analog supply and 2.7–5.25 V digital supply. It delivers 70 dB SINAD, 88 dB SFDR, and ±0.5 LSB INL (max) across –40°C to +85°C, targeting high-speed data acquisition in communications and instrumentation systems.
For engineers reviewing the AD9220ARSZ-REEL datasheet, AD9220ARSZ-REEL pinout, AD9220ARSZ-REEL application, or AD9220ARSZ-REEL equivalent, key selection criteria include its 10 MSPS sampling rate, 250 mW typical power consumption, straight-binary output format, and compatibility with both differential and single-ended analog inputs up to 5 Vp-p.
Technical Context
The AD9220ARSZ-REEL employs a 4-stage differential pipelined architecture with digital error correction logic, ensuring guaranteed no-missing-codes over temperature and enabling 12-bit accuracy at 10 MSPS. Its sample-and-hold amplifier supports flexible input configurations - including dc-coupled differential, ac-coupled single-ended, and variable common-mode voltage - with full-power bandwidth of 60 MHz and aperture jitter of 4 ps rms.
Internal voltage reference options (1 V or 2.5 V) allow trade-offs between input span (2 Vp-p or 5 Vp-p) and noise performance (0.09 LSB rms at 2.5 V ref). The device uses rising-edge clock sampling, exhibits 3-clock-cycle pipeline latency, and provides an out-of-range (OTR) flag synchronized to the MSB for overflow detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit guaranteed, no missing codes over full temperature range |
| Max Conversion Rate | 10.0 MSPS - enables real-time digitization of IF signals up to 5 MHz Nyquist bandwidth |
| SINAD / ENOB | 70 dB / 11.3 bits at 100 kHz input - supports high-fidelity signal capture in baseband applications |
| SFDR | 88 dB typ at 100 kHz - critical for detecting low-level spurs in spectral analysis and comms receivers |
| Input Referred Noise | 0.09 LSB rms at 2.5 V reference - translates to ~110 µVrms noise floor for 5 Vp-p full-scale |
| Power Consumption | 254 mW typ at 10 MSPS - balances speed and thermal budget in compact embedded systems |
| Aperture Jitter | 4 ps rms - limits SNR degradation to <0.1 dB at 10 MHz input frequency |
Pinout & Package
AD9220ARSZ-REEL is housed in a 28-lead SSOP (Shrink Small Outline Package) with 0.635 mm lead pitch and exposed pad for thermal enhancement. Pin compatibility with AD9221/AD9223 allows drop-in replacement within the same family.

| VREF / REFCOM | Reference I/O | Configurable 1 V or 2.5 V internal reference; REFCOM is reference ground return path |
| BIT 1 (MSB) to BIT 12 (LSB) | Digital Output Data | Straight-binary format; latched on clock edge; compatible with 3.3 V or 5 V logic families |
| OTR | Out-of-Range Indicator | Active-high flag synchronized to MSB - enables real-time overflow detection without additional logic |
| AVDD / AVSS / DVDD / DVSS | Power Supplies | Separate analog (5 V) and digital (2.7–5.25 V) rails minimize supply coupling noise |
| SENSE | Reference Select | Logic-high selects 2.5 V mode; logic-low selects 1 V mode - configures full-scale input span |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit, medium-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9223ARSZ-REEL | 3 MSPS max rate, 100 mW power, identical pinout and interface | Better suited for lower-bandwidth control loops or battery-powered sensors where 10 MSPS is unnecessary | Select when system clock constraints or thermal limits preclude 10 MSPS operation |
| ADS8326IPW | 16-bit, 500 kSPS SAR ADC, 3.3 V only, no internal reference | Higher resolution but lower speed; requires external reference and driver for wideband signals | Choose for precision DC/low-frequency measurements where ENOB >12 bits is mandatory |
Compared with AD9223ARSZ-REEL, AD9220ARSZ-REEL delivers 3.3× higher throughput at 2.5× higher power; versus ADS8326IPW, it trades 4-bit resolution for 20× speed and integrated analog front-end functionality - making it optimal for real-time signal processing rather than static measurement.

FAQ
What is the maximum sampling rate supported by the AD9220ARSZ-REEL?
The AD9220ARSZ-REEL supports a maximum conversion rate of 10.0 MSPS, as specified in its datasheet under AC and switching specifications. This rate is achievable with a minimum clock period of 100 ns and requires proper layout to minimize jitter. At this rate, the AD9220ARSZ-REEL maintains 70 dB SINAD and 88 dB SFDR for input frequencies up to 100 kHz, with performance degrading predictably at higher input frequencies per the typical performance curves.
Does the AD9220ARSZ-REEL require an external voltage reference?
No, the AD9220ARSZ-REEL includes a fully integrated, programmable voltage reference that can be configured for either 1.0 V or 2.5 V output via the SENSE pin. When using the internal reference, VREF and REFCOM pins must be properly decoupled per the layout guidelines. An external reference may be substituted if tighter initial accuracy or lower temperature drift is required, but doing so disables the internal reference circuitry.
How does the AD9220ARSZ-REEL handle overflow conditions during conversion?
The AD9220ARSZ-REEL provides an active-high Out-of-Range (OTR) signal that asserts synchronously with the most significant bit (BIT 1) when the analog input exceeds the valid range defined by VREF. This flag allows real-time detection of clipping without post-processing. For example, if VREF = 2.5 V, OTR activates when |VINA – VINB| > 5 Vp-p, enabling immediate corrective action in closed-loop systems or data tagging in acquisition firmware.
Can the AD9220ARSZ-REEL operate with a 3.3 V digital supply?
Yes, the AD9220ARSZ-REEL supports DVDD from 2.7 V to 5.25 V, making it compatible with 3.3 V digital systems. Its digital outputs are specified to drive 3.3 V logic levels (VOH ≥ 2.80 V at 0.5 mA), and the input thresholds (VIH = 3.5 V min, VIL = 1.0 V max) remain compatible when DVDD = 3.3 V. However, AVDD must remain at 5 V ±5% to maintain analog performance specifications.
What package type is used for the AD9220ARSZ-REEL?
The AD9220ARSZ-REEL is packaged in a 28-lead Shrink Small Outline Package (SSOP) with suffix "RS", denoted by "ARS" in the part number. It features a 0.635 mm lead pitch, gull-wing leads, and an exposed thermal pad. This package shares pinout and footprint compatibility with the SOIC variant (AD9220AR), allowing board-level interchangeability within the AD922x family when thermal and space constraints permit.
