Product details
Overview
AD9222ABCPZ-40 from Analog Devices is an octal, 12-bit, 40 MSPS serial LVDS analog-to-digital converter operating from a single 1.8 V supply, delivering 70 dB SNR and 11.3 ENOB at Nyquist with 325 MHz full-power analog bandwidth. It integrates eight ADC channels in one RoHS-compliant 64-lead LFCSP package and supports medical ultrasound beamforming and quadrature radio receiver front-ends.
For engineers reviewing the AD9222ABCPZ-40 datasheet, AD9222ABCPZ-40 pinout, AD9222ABCPZ-40 application, or AD9222ABCPZ-40 equivalent, key selection criteria include its 40 MSPS sampling rate, serial LVDS output compliance (ANSI-644), per-channel 114 mW power at full speed, programmable clock/data alignment, and industrial temperature range (−40°C to +85°C).
Technical Context
The AD9222ABCPZ-40 implements eight independent pipeline ADC cores sharing a common 1.8 V AVDD and DRVDD supply, each with dedicated differential analog inputs (VIN±A–H) and LVDS serial data outputs (D±A–H). Its on-chip sample-and-hold operates up to 40 MSPS with aperture jitter <1 ps rms and 8-clock-cycle pipeline latency.
It features dual clock-domain synchronization: a differential LVDS/CMOS/LVPECL-compatible input clock (CLK±) drives conversion, while internally multiplied DCO± and FCO± outputs support DDR data capture and byte framing. Serial port interface (SPI) enables real-time configuration of power modes, test patterns, resolution, and timing alignment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12 bits - delivers 4096 discrete amplitude levels for high-fidelity signal digitization in ultrasound and RF applications. |
| Sampling Rate | 40 MSPS - supports baseband digitization of signals up to 20 MHz (Nyquist) with minimal aliasing in portable imaging systems. |
| SNR / ENOB | 70 dB / 11.3 bits - ensures >70 dB dynamic range and <0.3 LSB DNL for accurate reconstruction of low-amplitude echoes in medical beamforming. |
| Analog Bandwidth | 325 MHz - enables direct sampling of IF signals up to 70 MHz without external amplification or filtering in diversity receivers. |
| Supply Voltage | 1.8 V AVDD & DRVDD - reduces system power and simplifies power delivery versus 3.3 V or 5 V ADCs, critical for battery-powered ultrasound devices. |

Pinout & Package
The AD9222ABCPZ-40 is housed in a RoHS-compliant, thermally enhanced 64-lead LFCSP (Lead Frame Chip Scale Package) with exposed paddle connected to AGND. Package dimensions are 9 mm × 9 mm × 0.85 mm (body), with 0.5 mm pitch and 0.4 mm standoff.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVDD (Pins 1,4,7,8,11,12,37,42,45,48,51,59,62) | Analog supply rail | 1.8 V power for all eight ADC cores and internal reference; requires local 100 nF + 10 µF decoupling per group. |
| VIN±A–H (Pins 2–3,5–6,43–44,46–47,49–50,52–53,60–61,63–64) | Differential analog inputs | Eight independent 2 V p-p full-scale input pairs; AC-coupled operation supported with internal 1.0 V reference. |
| D±A–H (Pins 15–16,17–18,19–20,21–22,27–28,29–30,31–32,33–34) | LVDS serial data outputs | Eight differential 12-bit serial streams (MSB-first default); each pair supports ANSI-644 or reduced-swing LVDS mode. |
| CLK± (Pins 9–10) | Differential sampling clock input | Accepts LVDS/CMOS/LVPECL clocks; minimum 10 MSPS, maximum 40 MSPS; determines conversion timing and pipeline latency. |
| DCO± / FCO± (Pins 23–24 / 25–26) | Data and frame clock outputs | DCO± clocks data capture; FCO± marks start of new byte; both derived from CLK± and enable synchronous DDR readout. |
| PDWN (Pin 41) | Global power-down control | Active-low signal placing entire device into <2 mW standby; supports rapid wake-up (<375 µs) for burst-mode acquisition. |
Key Features
| Feature | Design Value |
|---|---|
| Octal integration in single LFCSP | Reduces board area by >70% vs. eight discrete 12-bit ADCs; eliminates inter-channel skew and layout mismatch in beamforming arrays. |
| Programmable clock/data alignment | SPI-adjustable delay between DCO and data edges ensures reliable setup/hold timing across PVT variations without FPGA-level deskew logic. |
| Built-in digital test pattern generation | Supports deterministic (ramp, checkerboard) and pseudorandom patterns via SPI-enables production testing without external signal sources. |
| Individual-channel power-down | Each ADC core can be disabled independently via SPI, reducing dynamic power proportionally-critical for adaptive channel gating in ultrasound. |
| Flexible bit orientation | Configurable MSB/LSB-first serialization and offset binary coding allow seamless integration with existing DSP/FPGA data paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9252BCPZ-40 | 14-bit resolution, same 64-lead LFCSP package and pinout; higher 74 dB SNR but 1.2× power consumption. | Better suited for high-dynamic-range radar or spectrum analysis where 2 extra bits justify added power and cost. | Select AD9252BCPZ-40 when ENOB >12 bits is required and system power budget allows ~850 mW total dissipation. |
| AD9212BCPZ-40 | 10-bit resolution, identical footprint and interface; lower 62 dB SNR but 40% less power (440 mW typical). | Ideal for cost-sensitive, lower-fidelity applications like basic signal monitoring or legacy telecom interfaces. | Choose AD9212BCPZ-40 when 10-bit accuracy suffices and thermal constraints demand sub-500 mW operation. |
Compared with AD9222ABCPZ-40, AD9252BCPZ-40 trades 2 bits of resolution and 140 mW extra power for 4 dB SNR improvement, while AD9212BCPZ-40 sacrifices 2 bits and 8 dB SNR to cut power by nearly half-making AD9222ABCPZ-40 the optimal balance for mid-tier ultrasound and communications systems.

FAQ
What is the maximum sampling rate supported by the AD9222ABCPZ-40?
The AD9222ABCPZ-40 supports a maximum sampling rate of 40 MSPS, as indicated by the "-40" suffix in its part number. This rate is guaranteed across the full industrial temperature range (−40°C to +85°C) with specified AC performance including 70 dB SNR and 11.3 ENOB at Nyquist. The device also supports lower rates down to 10 MSPS, enabling flexible clocking for power-sensitive applications.
Does the AD9222ABCPZ-40 require an external voltage reference?
No, the AD9222ABCPZ-40 includes an internal 1.0 V reference and does not require an external reference for standard operation. The VREF, REFT, and REFB pins support optional external reference configurations, but the default mode uses the internal reference with ±21 ppm/°C drift and ±30 mV output error. SENSE pin selection determines reference mode, and RBIAS sets core bias current.
How many analog input channels does the AD9222ABCPZ-40 provide?
The AD9222ABCPZ-40 provides eight fully differential analog input channels labeled VIN±A through VIN±H, corresponding to eight independent ADC cores. Each channel accepts a 2 V p-p differential input with common-mode voltage fixed at AVDD/2 (0.9 V), and all channels share the same 1.8 V AVDD supply and clock domain for precise inter-channel timing alignment.
What digital output interface does the AD9222ABCPZ-40 use?
The AD9222ABCPZ-40 uses a serial LVDS interface compliant with ANSI-644, delivering 12-bit data per channel in MSB-first order by default. It provides eight differential data pairs (D±A–H), plus dedicated DCO± (data clock) and FCO± (frame clock) outputs to synchronize capture. A low-power LVDS option with reduced 150–250 mV output swing is also programmable via SPI.
Is the AD9222ABCPZ-40 pin-compatible with other members of the AD92xx family?
Yes, the AD9222ABCPZ-40 is pin-compatible with the AD9212 (10-bit) and AD9252 (14-bit) octal ADCs in the same 64-lead LFCSP package. This allows hardware reuse across resolution tiers-designers can upgrade or downgrade resolution without changing PCB layout, provided system firmware accommodates differing data widths and timing parameters.
