Product details
Overview
AD9220ARS-REEL 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 a single 5 V analog supply and 2.7–5.25 V digital supply. It integrates a low-noise sample-and-hold amplifier, programmable internal voltage reference (1 V or 2.5 V), and straight-binary output logic. It is used in high-speed data acquisition systems requiring precise dc linearity and wideband ac performance.
For engineers reviewing the AD9220ARS-REEL datasheet, AD9220ARS-REEL pinout, AD9220ARS-REEL application, or AD9220ARS-REEL equivalent, this page delivers verified technical context, exact pin functions, real-world application mappings, and validated alternative options - all grounded in the AD9220 family's official Rev. E specification and ordering guide.
Technical Context
The AD9220ARS-REEL employs a four-stage differential pipelined architecture with digital error correction logic, enabling guaranteed 12-bit no-missing-codes operation across –40°C to +85°C. Its sample-and-hold amplifier supports both single-ended and differential inputs with configurable common-mode level (via CML pin) and flexible input spans (2 V or 5 V p-p).
It uses edge-sensitive clocking: sampling occurs on the rising edge of CLK, while the SHA tracks during the low phase and holds during the high phase. Pipeline latency is fixed at three clock cycles, and the out-of-range (OTR) signal provides overflow detection synchronized to the MSB for unambiguous over/underflow identification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit guaranteed, with no missing codes over full temperature range - ensures full 4096-code fidelity in precision measurement systems. |
| Max Conversion Rate | 10.0 MSPS - enables digitization of signals up to 5 MHz Nyquist bandwidth in undersampled applications. |
| SINAD / ENOB | 70 dB / 11.3 bits at 100 kHz input - supports high-fidelity baseband sampling in medical imaging and instrumentation. |
| Input Referred Noise | 0.09 LSB rms (with 2.5 V reference) - contributes <0.02% RMS noise floor relative to full-scale, critical for low-amplitude signal capture. |
| Integral Nonlinearity | ±0.5 LSB max - limits end-point error to ±0.012% of full scale, preserving accuracy in calibration-critical systems. |
| Power Consumption | 254 mW typical (59 mW for AD9221, 100 mW for AD9223) - scales with speed, allowing thermal-aware selection within same footprint. |
| Reference Options | Internal 1 V or 2.5 V (±35 mV tolerance), or external reference via VREF/REFCOM - enables trade-off between simplicity and dc drift control. |
Pinout & Package
AD9220ARS-REEL is housed in a 28-lead SSOP (RS-28) package with 0.635 mm lead pitch and exposed pad for thermal management. Pin compatibility across AD9221/AD9223/AD9220 allows drop-in speed upgrades without layout change.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Clock Input | Single-ended CMOS/TTL-compatible input controlling all conversion timing; rising edge triggers sampling. |
| VINA / VINB | Differential Analog Inputs | Accepts true differential or single-ended signals; core input is VINA – VINB, bounded by ±VREF. |
| VREF / REFCOM | Reference I/O Pair | VREF sets full-scale range (1 V or 2.5 V); REFCOM is reference return - must be tied to AVSS if using internal reference. |
| SENSE | Reference Mode Select | High = 2.5 V internal reference; low = 1 V internal reference - configures gain and noise performance. |
| BIT 1 (MSB) to BIT 12 (LSB) | Parallel Digital Outputs | Straight-binary format, 3-state capable; compatible with 3.3 V or 5 V logic families depending on DVDD setting. |
| OTR | Out-of-Range Indicator | Active-high flag synchronized to MSB; distinguishes positive overflow (MSB=1, OTR=1) from negative overflow (MSB=0, OTR=1). |
| CAPB / CAPT | Noise Reduction Terminals | Connect 0.1 µF ceramic capacitors to AVSS to stabilize internal reference and reduce high-frequency noise. |
| CML | Common-Mode Level | Bias point for differential input stage; typically tied to AVDD/2 (2.5 V) to optimize THD and SNR. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic 12-bit ADC with integrated SHA and reference | Eliminates need for external sample-hold, reference buffer, or trimming components - reduces BOM count and board area in compact DAQ modules. |
| Flexible input configuration (single-ended/differential, 2 V or 5 V span) | Supports direct connection to op-amp drivers, transformer-coupled IF stages, or DC-coupled sensors without level-shifting circuitry. |
| Low aperture jitter (4 ps rms) | Enables >10-bit ENOB at multi-MHz input frequencies - essential for direct IF sampling in communications receivers. |
| 3-cycle pipeline latency with deterministic timing | Allows precise time-of-arrival alignment in synchronized multi-channel systems using common clock distribution. |
| Pin-compatible family (AD9221/AD9223/AD9220) | Permits design reuse across performance tiers: replace AD9220ARS-REEL with AD9223ARS-REEL for lower power at 3 MSPS without PCB revision. |

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 |
|---|---|---|---|
| AD9220AR-REEL | Same electrical specs and pinout, but in 28-lead SOIC (R-28) instead of SSOP (RS-28); higher θJA (71.4°C/W vs. 63.3°C/W). | Preferred for through-hole prototyping or legacy SOIC footprints; less suitable for high-density SMT layouts. | Select AD9220AR-REEL only when board assembly process or mechanical constraints require SOIC packaging. |
| ADS8325IPFBT | 16-bit, 100 kSPS SAR ADC (TI); no pipeline latency, lower power (15 mW), but 100× slower sampling rate and no integrated SHA. | Used in high-resolution, low-speed applications like precision sensor readout - not viable for real-time 10 MSPS streaming. | Choose ADS8325IPFBT only when resolution >12 bits and speed <100 kSPS suffice; not a functional replacement for AD9220ARS-REEL. |
Compared with AD9220AR-REEL, AD9220ARS-REEL offers superior thermal performance in space-constrained layouts, while ADS8325IPFBT trades speed and integration for resolution - making AD9220ARS-REEL the sole fit for 10 MSPS, 12-bit, monolithic ADC requirements with integrated reference and SHA.

FAQ
What is the maximum sampling rate supported by the AD9220ARS-REEL?
The AD9220ARS-REEL supports a maximum conversion rate of 10.0 MSPS, as specified in the Rev. E datasheet under AC Specifications. This rate is guaranteed across the full industrial temperature range (–40°C to +85°C) with AVDD = 5 V, DVDD = 5 V, and VREF = 2.5 V. The minimum clock period is 100 ns, corresponding to a 10 MHz clock frequency.
Does the AD9220ARS-REEL require an external reference voltage?
No, the AD9220ARS-REEL includes a programmable internal voltage reference with two selectable outputs: 1 V or 2.5 V, configured via the SENSE pin. External reference operation is optional and supported via the VREF and REFCOM pins, but not required - the internal reference delivers ±35 mV tolerance at 2.5 V mode and enables full functionality of AD9220ARS-REEL out-of-the-box.
How does the OTR (Out-of-Range) signal function in the AD9220ARS-REEL?
The OTR signal in AD9220ARS-REEL is an active-high, synchronous flag indicating analog input overflow. When OTR = 1, the input exceeded ±VREF range: if BIT 1 (MSB) = 1, it indicates positive overflow; if BIT 1 = 0, it indicates negative overflow. This dual-signal encoding allows unambiguous detection of over/underflow conditions without additional logic, directly supporting auto-ranging firmware in AD9220ARS-REEL-based systems.
Can the AD9220ARS-REEL operate with a 3.3 V digital supply?
Yes, the AD9220ARS-REEL supports DVDD from 2.7 V to 5.25 V, including standard 3.3 V logic levels. Its digital outputs are fully compatible with 3.3 V CMOS/TTL families when DVDD = 3.3 V, delivering VOH ≥ 2.80 V (IOH = 0.5 mA) and VOL ≤ 0.4 V (IOL = 1.6 mA). This allows seamless interfacing with FPGAs and microcontrollers operating at 3.3 V without level shifters.
What is the thermal resistance (θJA) of the AD9220ARS-REEL package?
The AD9220ARS-REEL uses a 28-lead SSOP (RS-28) package with a junction-to-ambient thermal resistance (θJA) of 63.3°C/W, as documented in the Thermal Characteristics section of the Rev. E datasheet. This value assumes standard JEDEC 2-layer board conditions and is 8.1°C/W lower than the SOIC variant (θJA = 71.4°C/W), reflecting improved heat dissipation in the SSOP footprint - critical for sustained 254 mW operation in compact enclosures.
