Analog Devices Inc. AD9223ARSZ-REEL

Overview

AD9223ARSZ-REEL from Analog Devices is a monolithic 12-bit analog-to-digital converter with 3.0 MSPS sampling rate, single 5 V analog supply (AVDD), and 3.0–5.25 V digital supply (DVDD). It integrates a low-noise sample-and-hold amplifier, programmable internal voltage reference (1 V or 2.5 V), and straight-binary digital output. It delivers 70 dB SINAD, 87.5 dB SFDR, and ±0.5 LSB INL for precision data acquisition in instrumentation and communications.

For engineers reviewing the AD9223ARSZ-REEL datasheet, AD9223ARSZ-REEL pinout, AD9223ARSZ-REEL application, or AD9223ARSZ-REEL equivalent, key selection criteria include its 3 MSPS throughput, 100 mW typical power consumption, 28-lead SSOP package, differential/single-ended input flexibility, and guaranteed no missing codes over –40°C to +85°C.

Technical Context

The AD9223ARSZ-REEL employs a 4-stage differential pipelined architecture with digital error correction logic, enabling true 12-bit accuracy and guaranteed no missing codes across temperature. Its sample-and-hold amplifier supports both single-ended and differential inputs with configurable common-mode level (via CML pin) and selectable input spans (2 V or 5 V p-p).

Internal timing uses the rising edge of CLK for sampling; pipeline latency is fixed at 3 clock cycles. The device accepts external references or operates with its internal 1 V/2.5 V reference, and features an out-of-range (OTR) flag synchronized to the data output for overflow detection.

FAQ

What is the maximum sampling rate supported by the AD9223ARSZ-REEL?

The AD9223ARSZ-REEL supports a maximum conversion rate of 3.0 MSPS, as specified in its datasheet under AC and switching specifications. This rate is guaranteed over the full industrial temperature range (–40°C to +85°C) with AVDD = 5 V, DVDD = 5 V, and proper decoupling. At this rate, the minimum clock period is 333 ns, and pipeline latency remains fixed at three clock cycles. The AD9223ARSZ-REEL maintains 70 dB SINAD and 87.5 dB SFDR performance at its rated 3 MSPS throughput.

Does the AD9223ARSZ-REEL require an external voltage reference?

No, the AD9223ARSZ-REEL does not require an external voltage reference. It integrates a programmable internal reference that can be configured for either 1 V or 2.5 V output via the SENSE pin. When using the internal reference, CAPT and CAPB pins must be bypassed to AVSS with 0.1 µF capacitors. An external reference may be applied to the VREF pin if higher dc accuracy or custom reference voltage is needed, but the AD9223ARSZ-REEL operates fully functional with its internal reference enabled.

What package type is used for the AD9223ARSZ-REEL?

The AD9223ARSZ-REEL is packaged in a 28-lead SSOP (Shrink Small Outline Package), also designated RS-28 in Analog Devices' ordering guide. It has a 0.635 mm lead pitch, conforms to JEDEC MO-153, and is RoHS-compliant. This package shares identical pinout and footprint with the 28-lead SOIC (R-28) variant, enabling layout reuse across speed grades (AD9221/AD9223/AD9220) when thermal or board-space constraints favor the smaller SSOP body.

How does the AD9223ARSZ-REEL handle input overrange conditions?

The AD9223ARSZ-REEL provides an out-of-range (OTR) flag that asserts high when the analog input exceeds the valid range defined by ±VREF at the core. This flag is synchronous with the data output and updated on each conversion cycle. For example, with VREF = 2.5 V, OTR activates when VINA – VINB > +2.5 V or < –2.5 V. The OTR signal allows real-time detection of saturation without post-processing, and is especially useful in AGC loops or fault-monitoring circuits. The AD9223ARSZ-REEL continues normal conversion during overrange events.

Can the AD9223ARSZ-REEL operate with a 3.3 V digital supply?

Yes, the AD9223ARSZ-REEL 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 standard CMOS voltage thresholds at 3.3 V: VOH ≥ 2.80 V (IOH = 0.5 mA), VOL ≤ 0.4 V (IOL = 1.6 mA). The analog supply AVDD remains fixed at 5 V ±5%, but DVDD may be independently regulated at 3.3 V to reduce digital domain power and improve noise isolation. This dual-supply flexibility simplifies integration into mixed-voltage systems.
