Product details
Overview
AD9220AR-REEL from Analog Devices is a monolithic 12-bit analog-to-digital converter with 10.0 MSPS sampling rate, 70 dB SINAD, ±0.5 LSB integral nonlinearity, and straight binary output. It integrates a sample-and-hold amplifier and programmable voltage reference, and is used in high-speed data acquisition systems requiring precise digitization of analog signals up to 60 MHz bandwidth.
For engineers reviewing the AD9220AR-REEL datasheet, AD9220AR-REEL pinout, AD9220AR-REEL application, or AD9220AR-REEL equivalent, this page delivers verified specifications, package mapping, functional pin roles, real-world use cases, and validated alternative parts for signal chain design, medical imaging front-ends, and communications IF sampling.
Technical Context
The AD9220AR-REEL employs a 4-stage differential pipelined architecture with digital error correction logic, enabling guaranteed 12-bit no-missing-codes performance across –40°C to +85°C. Its sample-and-hold amplifier supports both single-ended and differential inputs with configurable common-mode level (CML) and input spans of 2 Vp-p or 5 Vp-p.
It uses a single 5 V analog supply (AVDD) and 2.7–5.25 V digital supply (DVDD), with clock-driven conversion synchronized on the rising edge. Pipeline latency is fixed at 3 clock cycles, and the out-of-range (OTR) flag provides overflow detection alongside MSB for polarity resolution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit guaranteed, no missing codes over full temperature range - ensures full 4096-code fidelity in precision measurement. |
| Max Conversion Rate | 10.0 MSPS - supports Nyquist-limited sampling of signals up to 5 MHz, or direct IF sampling at higher frequencies. |
| SINAD / ENOB | 70 dB / 11.3 bits at 100 kHz input - enables accurate low-distortion digitization for spectral analysis and baseband capture. |
| INL / DNL | ±0.5 LSB max / ±0.3 LSB typ - maintains linearity critical for calibration-sensitive applications like medical ADC front-ends. |
| Input Referred Noise | 0.09 LSB rms (VREF = 2.5 V) - contributes <100 µVrms noise floor, supporting sub-millivolt signal resolution. |
| Power Consumption | 254 mW typ at 10 MSPS - balances speed and efficiency for thermally constrained embedded systems. |
| Full Power Bandwidth | 60 MHz - allows faithful digitization of fast transients and wideband IF signals without amplitude roll-off. |
Pinout & Package
AD9220AR-REEL is housed in a 28-lead SOIC (R-28) package with standard JEDEC MS-013AC footprint, 1.27 mm pitch, and 17.9 mm × 7.5 mm body size. Thermal resistance is θJA = 71.4°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Clock Input | Rising-edge-triggered master clock; minimum pulse width 45 ns - defines maximum 10 MSPS throughput and timing budget. |
| VINA / VINB | Differential Analog Inputs | Accepts true differential or single-ended signals; input span selectable via VREF (2 V or 5 V p-p) - enables flexible sensor/IF interface. |
| VREF / REFCOM | Reference I/O and Common | Supports internal 1 V or 2.5 V reference (±35 mV tolerance) or external reference - determines full-scale range and dc accuracy. |
| BIT 1 (MSB) to BIT 12 (LSB) | Parallel Digital Outputs | Straight binary format; 3-state capable with DVDD = 3 V or 5 V - interfaces directly with FPGA or microcontroller GPIO banks. |
| OTR | Out-of-Range Indicator | Active-high flag asserted when input exceeds ±VREF - used with MSB to distinguish high/low overflow without additional logic. |
| SENSE | Reference Select Control | Configures internal reference mode (1 V or 2.5 V) - sets gain and noise floor for optimal dynamic range selection. |
| AVDD / AVSS / DVDD / DVSS | Analog & Digital Supplies/Grounds | Separate analog/digital domains minimize coupling; AVSS and DVSS must be isolated at PCB level - essential for SNR preservation. |
| CAPT / CAPB / CML | Noise Reduction & Common-Mode Bias | CAPT/CAPB stabilize internal reference; CML sets mid-supply bias point (2.5 V) - critical for THD optimization in differential mode. |
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 layout area by ≥40%. |
| Flexible input configuration (single-ended/differential, 2 V or 5 V p-p) | Enables reuse across sensor, IF, and DC-coupled acquisition channels without hardware change - accelerates multi-platform design. |
| Guaranteed no missing codes over temperature | Ensures monotonicity in closed-loop control and servo feedback paths - prevents instability due to code ambiguity. |
| Low aperture jitter (4 ps rms) | Preserves SFDR >77.5 dB at 5 MHz input - critical for high-fidelity spectrum analysis and radar pulse capture. |
| 3-cycle pipeline latency with deterministic timing | Allows predictable synchronization with FPGA logic or DSP frame boundaries - simplifies timing closure in real-time processing. |

FAQ
What is the maximum sampling rate supported by the AD9220AR-REEL?
The AD9220AR-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 decoupling and layout to maintain SFDR >77.5 dB. The device maintains full 12-bit performance at this rate across its operating temperature range of –40°C to +85°C.
Does the AD9220AR-REEL include an internal voltage reference?
Yes, the AD9220AR-REEL integrates a programmable internal voltage reference that can be configured for either 1.0 V or 2.5 V output via the SENSE pin. The 2.5 V mode offers ±35 mV tolerance and supports 5 Vp-p input span, while the 1.0 V mode enables 2 Vp-p span with lower noise floor. An external reference may also be applied through the VREF pin if tighter dc accuracy is required.
Can the AD9220AR-REEL operate with a 3.3 V digital supply?
Yes, the AD9220AR-REEL supports DVDD from 2.7 V to 5.25 V, including standard 3.3 V logic levels. Its digital outputs are compatible with both 3.3 V and 5 V CMOS/TTL families, with VOH ≥2.80 V (IOH = 0.5 mA) and VOL ≤0.4 V (IOL = 1.6 mA) at DVDD = 3 V. This allows direct interfacing with modern FPGAs and microcontrollers without level-shifting circuitry.
What does the OTR (Out-of-Range) signal indicate on the AD9220AR-REEL?
The OTR signal on the AD9220AR-REEL is an active-high indicator that asserts when the analog input exceeds the valid range defined by ±VREF. When OTR is high, the MSB (BIT 1) indicates polarity: high MSB denotes positive overflow, low MSB denotes negative overflow. This enables precise saturation detection and automatic gain control (AGC) in real-time signal processing chains.
Is the AD9220AR-REEL pin-compatible with other members of the AD922x family?
Yes, the AD9220AR-REEL shares identical pinout, package (28-lead SOIC), and interface with AD9221AR-REEL and AD9223AR-REEL. All three devices support the same analog input structure, reference configuration, digital output format, and timing behavior - enabling drop-in replacement based solely on required sampling rate and power budget without PCB redesign.
