AD9230BCPZ-250

Overview

The AD9230BCPZ-250 is a 12-bit monolithic sampling analog-to-digital converter optimized for high performance and low power. It operates at a maximum conversion rate of 250 MSPS with a 700 MHz full-power analog bandwidth. The device requires a single 1.8 V supply for both analog and digital sections. Digital outputs utilize LVDS signaling compliant with ANSI-644 levels, supporting selectable data formats including offset binary, two's complement, and Gray code. It features an integrated track-and-hold circuit and voltage reference, eliminating the need for external decoupling.

Feature Summary

• Integrated on-chip voltage reference and track-and-hold circuit simplify system design by removing the requirement for external components.
• LVDS digital outputs provide compatibility with current FPGA technology and include an integrated data capture clock for proper timing.
• Standard serial port interface supports configuration of output data formatting, gain adjustment, and power-down modes.

Applications

• Wireless and wired broadband communications
• Cable reverse path communications
• Communications test equipment
• Radar and satellite subsystems
• Power amplifier linearization

Procurement Notes

Verify the specific speed grade suffix matches the required sampling rate before procurement. Confirm that the LFCSP package thermal requirements are met in the target application. Ensure the ordering part number corresponds to the exact Analog Devices specification sheet for the AD9230 series to avoid functional mismatches.

Selection Notes

Select this component when a 12-bit resolution and 250 MSPS throughput are required within a single 1.8 V supply architecture. Consider the LVDS output interface for direct FPGA connectivity. Evaluate the power dissipation characteristics against the available thermal management capabilities of the PCB layout.

Part Context

The AD9230 belongs to a family of high-speed ADCs from Analog Devices designed for wideband carrier applications. It is fabricated using an advanced CMOS process and is housed in a 56-lead LFCSP package. The device is specified over the industrial temperature range of −40°C to +85°C.

Replacement Considerations

The AD9211 is a pin-compatible 10-bit version within the same family. Other speed grades such as AD9230-170 and AD9230-210 offer lower sampling rates but share the same package and pinout.
