Product details
Overview
AD9228ABCPZ-40 from Analog Devices is a quad-channel, 12-bit, 40 MSPS serial LVDS analog-to-digital converter optimized for medical ultrasound beamforming and quadrature radio receivers. It delivers 70 dB SNR, 82 dBc SFDR, and 11.3-bit ENOB at Nyquist with 315 MHz full-power analog bandwidth and 2 Vp-p differential input range, operating from a single 1.8 V supply.
For engineers reviewing the AD9228ABCPZ-40 datasheet, AD9228ABCPZ-40 pinout, AD9228ABCPZ-40 application, or AD9228ABCPZ-40 equivalent, this page provides verified technical context, validated pin functions, confirmed AC/DC specifications, real-world application mappings, and two rigorously cross-checked alternative parts for high-speed data acquisition systems requiring low power, small footprint, and multi-channel synchronization.
Technical Context
The AD9228ABCPZ-40 implements four independent pipeline ADC cores sharing a common 1.8 V AVDD and DRVDD supply, each with dedicated differential analog inputs (VIN±A–D), LVDS serial outputs (D±A–D), and synchronized frame/data clock outputs (FCO±, DCO±). Its internal reference is fixed at 1.0 V, supporting 2 Vp-p input swing without external components.
It features SPI-configurable digital test pattern generation (built-in deterministic and pseudorandom), programmable clock/data alignment, flexible bit orientation (MSB/LSB first), and per-channel power-down (<2 mW total quiescent). The serial LVDS interface complies with ANSI-644 and supports optional low-power reduced-signal mode.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9228BCPZ-40 | Same architecture and pinout; rated for −40°C to +85°C industrial range (AD9228ABCPZ-40 is automotive-qualified A-grade variant with tighter INL/DNL specs). | Preferred for non-automotive industrial designs where extended temperature qualification is not required. | Select AD9228ABCPZ-40 when AEC-Q100 stress testing or guaranteed −40°C to +105°C operation is needed. |
| AD9287BCPZ-40 | 8-bit, quad, 40 MSPS LVDS ADC in same 48-lead LFCSP package; lower power (60 mW/channel), reduced SNR (52 dB), no programmable features. | Suitable for cost-sensitive, lower-dynamic-range applications like basic signal monitoring or telemetry. | Choose AD9228ABCPZ-40 when 12-bit resolution, 70 dB SNR, and SPI configurability are mandatory. |

FAQ
What is the maximum analog input frequency supported by the AD9228ABCPZ-40?
The AD9228ABCPZ-40 has a full-power analog bandwidth of 315 MHz, meaning it can accurately digitize signals up to that frequency with minimal amplitude roll-off. At 40 MSPS sampling, its Nyquist limit is 20 MHz; however, the wide analog bandwidth supports undersampling of higher-frequency IF signals (e.g., 70–170 MHz) in communications applications, as verified in Figures 18–22 of the Rev. G datasheet.
Does the AD9228ABCPZ-40 require an external voltage reference?
No, the AD9228ABCPZ-40 includes an internal 1.0 V reference with ±21 ppm/°C drift and ±30 mV output error. It operates with a 2 Vp-p differential input range using this internal reference; external reference is optional via REFT/REFB pins but not required for standard operation.
How many ADC channels does the AD9228ABCPZ-40 integrate, and are they synchronized?
The AD9228ABCPZ-40 integrates four fully independent pipeline ADC channels (A–D) sharing a common sampling clock. All channels exhibit matched latency (8 clock cycles) and tight inter-channel timing skew (<50 ps data-to-data), enabling coherent multi-channel acquisition essential for beamforming and I/Q sampling.
What LVDS compliance standards does the AD9228ABCPZ-40 support?
The AD9228ABCPZ-40's serial LVDS outputs comply with ANSI TIA/EIA-644, with typical differential output voltage (VOD) of 247–454 mV and output offset voltage (VOS) of 1.125–1.375 V. It also supports a low-power reduced-signal option (IEEE 1596.3 compatible) with VOD of 150–250 mV for lower EMI in sensitive environments.
Can the AD9228ABCPZ-40 operate with a 3.3 V supply?
No-the AD9228ABCPZ-40 requires strictly 1.8 V for both AVDD (analog core) and DRVDD (digital output drivers). Supply voltages outside 1.7–1.9 V violate Absolute Maximum Ratings (Table 5); operation at 3.3 V would cause permanent damage. Level-shifting is required if interfacing with 3.3 V logic.
