Product details
Overview
AD9223AR-REEL from Analog Devices is a monolithic 12-bit analog-to-digital converter with 3.0 MSPS sampling rate, 70 dB SINAD, and ±0.5 LSB integral nonlinearity, operating on a single 5 V analog supply and 2.7–5.25 V digital supply. It integrates a sample-and-hold amplifier and programmable voltage reference, and is used in high-fidelity data acquisition systems requiring precise dc linearity and low-noise ac performance.
For engineers reviewing the AD9223AR-REEL datasheet, AD9223AR-REEL pinout, AD9223AR-REEL application, or AD9223AR-REEL equivalent, key selection criteria include guaranteed no missing codes over temperature, 3-cycle pipeline latency, straight binary output format, out-of-range (OTR) flag support, and compatibility with both 3.3 V and 5 V logic families.
Technical Context
The AD9223AR-REEL implements a four-stage differential pipelined architecture with digital error correction logic to ensure 12-bit accuracy and no missing codes across –40°C to +85°C. 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 the rising edge of CLK for sampling; the SHA operates in track mode during clock low and hold mode during clock high. Aperture jitter is specified at 4 ps rms, and full-power bandwidth reaches 40 MHz - enabling Direct-IF sampling applications beyond Nyquist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12 bits - guarantees 4096 distinct output codes with monotonic transfer function |
| Max Conversion Rate | 3.0 MSPS - supports real-time digitization of signals up to 1.5 MHz Nyquist bandwidth |
| SINAD / ENOB | 70 dB / 11.3 bits - enables high-fidelity signal reconstruction in instrumentation and medical imaging |
| INL / DNL | ±0.5 LSB / ±0.3 LSB - ensures accurate amplitude fidelity and absence of code gaps in precision measurement |
| Input Referred Noise | 0.09 LSB rms (at 2.5 V reference) - contributes <0.02% RMS noise floor relative to full-scale range |
| Power Consumption | 100 mW typical - balances performance and thermal management in compact embedded systems |
| Supply Voltages | AVDD = 5 V ±5%; DVDD = 2.7–5.25 V - allows interoperability with mixed-voltage FPGA or DSP interfaces |
Pinout & Package
AD9223AR-REEL is housed in a 28-lead SOIC package (R-28 option), with exposed pad not present and RoHS-compliant lead finish. 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 150 ns; controls all internal conversion cycles |
| VINA / VINB | Differential Analog Inputs | Accepts true differential or single-ended signals; core input is VINA – VINB; supports 2 V or 5 V p-p spans |
| VREF / REFCOM / SENSE | Reference Interface | VREF sets full-scale range (1 V or 2.5 V); SENSE selects internal/external reference; REFCOM is reference ground |
| BIT 1 (MSB) to BIT 12 (LSB) | Digital Output Data | Straight binary format; latched outputs drive 3.3 V or 5 V logic; 3-cycle pipeline latency |
| OTR | Out-of-Range Indicator | Active-high flag signaling overflow; used with MSB to distinguish high/low saturation conditions |
| AVDD / AVSS / DVDD / DVSS | Power and Ground | Separate analog/digital supplies reduce noise coupling; AVSS and DVSS must be connected with low-inductance path |

FAQ
What is the maximum sampling rate supported by the AD9223AR-REEL?
The AD9223AR-REEL supports a maximum conversion rate of 3.0 MSPS, as confirmed in the AC specifications table and switching timing section of the datasheet. This rate is guaranteed over the full operating temperature range of –40°C to +85°C with AVDD = 5 V, DVDD = 5 V, and VREF = 2.5 V. The device maintains 70 dB SINAD and no missing codes at this rate.
Does the AD9223AR-REEL require an external voltage reference?
No, the AD9223AR-REEL includes a programmable internal voltage reference configurable for either 1 V or 2.5 V output, with ±35 mV tolerance at 2.5 V mode. External reference is optional and only needed when tighter dc accuracy or lower temperature drift than the internal reference provides is required for the application.
What does the OTR (Out-of-Range) signal indicate on the AD9223AR-REEL?
The OTR signal on the AD9223AR-REEL is an active-high indicator that the analog input exceeded the valid range defined by ±VREF at the core. When asserted, it signals overflow - used with the MSB to determine whether saturation occurred at the positive or negative rail. This enables real-time clipping detection without post-processing.
Can the AD9223AR-REEL interface directly with a 3.3 V FPGA?
Yes, the AD9223AR-REEL's digital outputs are compatible with 3.3 V logic families. With DVDD = 3.3 V, VOH is guaranteed ≥2.80 V (IOH = 0.5 mA) and VOL ≤0.4 V (IOL = 1.6 mA), meeting standard 3.3 V CMOS input thresholds. No level-shifting circuitry is required for direct connection.
Is the AD9223AR-REEL pin-compatible with other members of the AD922x family?
Yes, the AD9223AR-REEL shares identical pinout, package (28-lead SOIC), and interface with AD9221AR-REEL and AD9220AR-REEL. All three devices support the same clocking scheme, output format, reference configuration, and power sequencing - enabling drop-in replacement based on required sample rate and power trade-offs.
