Product details
Overview
AD9252ABCPZRL7-50 from Analog Devices is an octal, 14-bit, 50 MSPS analog-to-digital converter with serial LVDS output, 1.8 V supply operation, and 325 MHz full-power analog bandwidth. It integrates eight independent ADC channels in a single 64-lead LFCSP package and delivers 73 dB SNR and 84 dBc SFDR at Nyquist for high-fidelity signal acquisition in ultrasound beamforming systems.
For engineers reviewing the AD9252ABCPZRL7-50 datasheet, AD9252ABCPZRL7-50 pinout, AD9252ABCPZRL7-50 application, or AD9252ABCPZRL7-50 equivalent, this page provides verified technical context, validated pin functions, confirmed AC/digital specifications, real-world application mappings, and two rigorously cross-checked alternative parts for multi-channel high-speed data acquisition designs.
Technical Context
The AD9252ABCPZRL7-50 implements a pipelined architecture with a 4-bit first stage, eight 1.5-bit stages, and a 3-bit flash final stage, enabling concurrent sampling and conversion across all eight channels. Each stage includes 1-bit redundancy for digital error correction, and sampling occurs on the rising edge of the input clock.
It supports dual LVDS output modes-ANSI-644 compliant (247–454 mV differential output voltage) and low-power reduced-signal mode (150–250 mV)-with programmable clock/data alignment, flexible bit orientation (MSB/LSB first), and built-in deterministic/pseudorandom test pattern generation via SPI interface.
Key Specifications

| PDWN | Global power-down control | Active-low; reduces total dissipation to <11 mW when all channels disabled |
| CSB / SCLK/DTP / SDIO/ODM | SPI serial port interface | 3-wire interface for configuration, test pattern loading, and register readback |
Key Features
| Feature | Design Value |
|---|---|
| Octal integration | Eight independent 14-bit ADCs in one 9 mm × 9 mm LFCSP - cuts board area by >75% vs. discrete quad solutions |
| Programmable output resolution | Supports 12-bit or 14-bit serialization via SPI - reduces FPGA I/O count and LVDS lane usage when lower precision suffices |
| Flexible clock/data alignment | Adjustable phase between DCO and serialized data (±300 ps range) - compensates for PCB trace skew without external delay lines |
| Built-in test patterns | Deterministic, pseudorandom, and custom user-defined patterns loaded via SPI - eliminates need for external signal generators during production test |
| Individual channel power-down | Each ADC can be disabled independently - enables dynamic channel gating in time-interleaved or adaptive beamforming architectures |
| Standby mode | Consumes 89 mW (vs. 773 mW active) - maintains configuration state while reducing thermal load during idle intervals |
Applications

FAQ
What is the absolute maximum analog input voltage for AD9252ABCPZRL7-50?
The AD9252ABCPZRL7-50 specifies an absolute maximum analog input voltage of −0.3 V to +2.0 V with respect to AGND per VIN± pin. Exceeding this range risks permanent damage. The recommended operating range is 2 V p-p differential (±1 V) centered at AVDD/2 (0.9 V), as defined in Table 1 of the Rev. E datasheet.
Does AD9252ABCPZRL7-50 require an external reference voltage?
No, AD9252ABCPZRL7-50 includes an internal 1.0 V reference with ±21 ppm/°C drift and ±30 mV output error. External reference is optional via VREF, REFT, and REFB pins; default operation uses internal reference, eliminating need for external components in most applications.
How many LVDS data lanes does AD9252ABCPZRL7-50 use per channel?
AD9252ABCPZRL7-50 uses one differential LVDS pair (D+ x / D− x) per ADC channel, totaling eight pairs for all eight channels. Each pair serializes 14 bits per sample at double-data-rate, resulting in a 1.4 Gbps aggregate output rate per channel at 50 MSPS.
What is the pipeline latency of AD9252ABCPZRL7-50?
The AD9252ABCPZRL7-50 has a fixed pipeline latency of 8 clock cycles, as specified in Table 4 (Switching Specifications). This value is constant across all operating conditions and must be accounted for in time-critical synchronization logic, such as digital beamforming or closed-loop control systems.
Can AD9252ABCPZRL7-50 operate with a 12-bit output mode?
Yes, AD9252ABCPZRL7-50 supports programmable 12-bit or 14-bit serialization via SPI register configuration (Register 0x14, Bit[1:0]). In 12-bit mode, the two LSBs are truncated, reducing FPGA I/O count and LVDS bandwidth requirements while maintaining full 50 MSPS throughput.
