Product details
Overview
AD9252ABCPZ-50 from Analog Devices is an octal, 14-bit, 50 MSPS analog-to-digital converter with serial LVDS outputs, 1.8 V supply operation, 325 MHz full-power analog bandwidth, and integrated sample-and-hold. It delivers 73 dB SNR and 84 dBc SFDR at Nyquist, targeting high-channel-count signal acquisition in ultrasound beamforming and quadrature radio receivers.
For engineers reviewing the AD9252ABCPZ-50 datasheet, AD9252ABCPZ-50 pinout, AD9252ABCPZ-50 application, or AD9252ABCPZ-50 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 multi-channel ADC selection.
Technical Context
The AD9252ABCPZ-50 implements a pipelined architecture with a 4-bit first stage, eight 1.5-bit stages, and a final 3-bit flash stage-enabling continuous sampling at 50 MSPS on the rising clock edge. Each stage includes redundancy and digital error correction to guarantee no missing codes and ±0.4 LSB typical DNL.
It integrates eight independent ADC cores sharing one 1.8 V AVDD rail and separate 1.8 V DRVDD for LVDS output drivers. Serial LVDS outputs (ANSI-644 compliant) support DDR data capture via dedicated DCO+/− and FCO+/− clocks, with programmable alignment and bit orientation per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit-supports high-fidelity digitization of wide-dynamic-range analog signals such as RF IF or medical ultrasound echoes. |
| Sampling Rate | 50 MSPS-enables baseband sampling up to 25 MHz or undersampling of IF signals up to 325 MHz analog bandwidth. |
| SNR / ENOB | 73 dB / 12 bits (to Nyquist)-ensures ≥12-bit effective precision for noise-sensitive applications like digital beamforming. |
| Power per Channel | 93.5 mW at 50 MSPS-delivers low power density for thermally constrained 8-channel systems without external cooling. |
| Analog Bandwidth | 325 MHz full-power-allows direct digitization of wideband RF/IF signals without external amplification or filtering. |
| Differential Input Range | 2 V p-p-matches standard transformer-coupled or balun-driven signal chains without attenuation or gain adjustment. |
| Output Interface | Serial LVDS (ANSI-644)-reduces EMI and supports long trace routing at high data rates with built-in DDR clocking (DCO/FCO). |
Pinout & Package
The AD9252ABCPZ-50 is housed in a RoHS-compliant, 64-lead LFCSP (Lead Frame Chip Scale Package) with exposed paddle (Pin 0) requiring connection to AGND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+ A to VIN+ H / VIN− A to VIN− H | Eight differential analog inputs | Accepts true/complement signals for all eight ADC channels; common-mode voltage fixed at AVDD/2 (0.9 V). |
| D+ A/D− A to D+ H/D− H | Eight differential LVDS data outputs | Serial 14-bit data streams per channel; default offset binary coding; supports programmable resolution (12/14-bit). |
| CLK+/CLK− | Differential sample clock input | Accepts LVDS/LVPECL/CMOS; 10–50 MSPS range; determines conversion timing and pipeline latency (8 clock cycles). |
| DCO+/DCO− & FCO+/FCO− | Dedicated LVDS clock outputs | DCO aligns with data edges for DDR capture; FCO marks byte boundaries; both programmable for phase alignment. |
| PDWN | Global power-down control | Active-low signal enabling full-chip or individual-channel shutdown; <2 mW total dissipation when all channels disabled. |
| SPI Interface (CSB, SCLK/DTP, SDIO/ODM) | Serial configuration port | Enables real-time setup of test patterns, clock/data alignment, output resolution, and power modes without external logic. |
Key Features
| Feature | Design Value |
|---|---|
| Octal integration in single package | Reduces PCB area by >70% vs. eight discrete 14-bit ADCs; eliminates inter-channel skew and layout mismatch. |
| Programmable digital test patterns | Includes deterministic, pseudorandom, and user-defined patterns loaded via SPI-enabling in-system ADC validation without external signal sources. |
| Flexible LVDS output modes | Supports standard ANSI-644 or low-power reduced-swing mode (150–250 mV), optimizing EMI and power for board-level routing constraints. |
| Per-channel power-down | Allows dynamic channel gating in time-interleaved or adaptive receive systems-cutting active channel count while preserving timing alignment. |
| Built-in clock multiplier | Automatically generates LVDS serial data rate from input clock (e.g., 50 MSPS clock → 700 Mbps serial stream), eliminating external PLLs. |
Applications
| Medical Ultrasound Beamforming | Quadrature Radio Receiver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9252BCPZ-50 | Same silicon, different temperature grade: −40°C to +85°C (ABCPZ) vs. −40°C to +105°C (BCPZ); identical AC/DC specs and pinout. | ABCPZ targets industrial equipment; BCPZ required for extended-temperature base stations or avionics. | Select AD9252ABCPZ-50 for cost-sensitive industrial ultrasound or test gear operating within standard industrial range. |
| AD9257BCPZ-50 | Quad-channel (not octal); same 14-bit/50 MSPS spec but half the channel count; shares SPI interface and LVDS output architecture. | Used where four synchronized channels suffice-e.g., dual-path I/Q with redundancy-not for full 8x beamforming. | Choose AD9252ABCPZ-50 when system-level channel count mandates eight simultaneous samples without interleaving complexity. |
Compared with AD9252BCPZ-50, the AD9252ABCPZ-50 offers identical performance at lower cost for standard-temperature applications; versus AD9257BCPZ-50, it doubles channel density without increasing board area or power per channel-critical for space-constrained medical or comms hardware.

FAQ
What is the maximum analog input frequency supported by the AD9252ABCPZ-50?
The AD9252ABCPZ-50 features a 325 MHz full-power analog bandwidth, meaning it maintains specified SNR and linearity up to 325 MHz input frequency when driven with a 2 V p-p differential signal. This enables direct RF sampling well into the UHF band, supporting undersampling architectures in communications and test equipment without external anti-alias filtering.
Does the AD9252ABCPZ-50 require an external reference voltage?
No-the AD9252ABCPZ-50 includes an internal 1.0 V reference with ±21 ppm/°C drift and ±2 mV output error. It can operate in buffered reference mode (VREF pin driven) or use the internal reference with REFT/REFB pins configured accordingly. External references are optional for enhanced stability or custom scaling.
How many power supplies does the AD9252ABCPZ-50 require?
The AD9252ABCPZ-50 requires two independent 1.8 V supplies: AVDD for analog circuitry (373.4 mA typical) and DRVDD for LVDS output drivers (58 mA typical). Both rails must be decoupled per the layout guidelines in the datasheet; AGND and DRGND are separate but tied at a single point near the exposed paddle.
Can the AD9252ABCPZ-50 output 12-bit data instead of 14-bit?
Yes-the AD9252ABCPZ-50 supports programmable output resolution via its SPI interface. Users may configure each channel independently for 12-bit or 14-bit output, with corresponding adjustments to data rate and LVDS timing. Default is 14-bit offset binary; 12-bit mode truncates LSBs and reduces serial throughput.
What is the pipeline latency of the AD9252ABCPZ-50?
The AD9252ABCPZ-50 has a fixed pipeline latency of 8 clock cycles from sample edge to valid serialized output. This value is constant across all operating conditions and is critical for time-critical applications such as closed-loop beamforming or real-time spectrum analysis where deterministic delay is required.
