AD9230BCPZ-170

Analog To Digital Converters (ADC) Overview

The AD9230BCPZ-170 is a 12-bit monolithic sampling analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum conversion rate of 170 MSPS. It utilizes a pipeline architecture and accepts differential or single-ended analog inputs with a programmable voltage range of 1.0 V to 1.5 V, nominally 1.25 V p-p. The device requires a single 1.8 V supply for both analog and digital sections. Digital outputs are provided in LVDS format compatible 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 on-chip voltage reference, eliminating the need for external decoupling.

Analog To Digital Converters (ADC) Feature Summary

• Integrated track-and-hold and voltage reference simplify system design by removing the need for external components.
• LVDS digital outputs support direct interface with FPGA technology and offer selectable output coding formats.
• Serial port control allows configuration of data formatting, power-down modes, gain adjustments, and test patterns.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix matches the required sample rate, as the AD9230 family includes variants rated for 170, 210, and 250 MSPS. Confirm that the LFCSP package thermal requirements are met through proper PCB ground plane soldering. Ensure the ordering part number corresponds exactly to the desired performance specifications and temperature range before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the AD9230BCPZ-170 when a maximum sampling rate of 170 MSPS is sufficient for the application bandwidth. Consider higher speed grades if input frequencies exceed those supported by this variant. Evaluate the power dissipation requirements against the available cooling solutions, noting that power consumption varies between SDR and DDR output modes. Verify compatibility with the system clock source regarding CMOS/LVDS/LVPECL logic compliance.

Analog To Digital Converters (ADC) Part Context

The AD9230 belongs to a pin-compatible family of high-speed ADCs from Analog Devices, which also includes the 10-bit AD9211. This family shares similar packaging and functional interfaces, allowing for potential design flexibility across different resolution requirements while maintaining board layout consistency. The component is fabricated on an advanced CMOS process and is specified for industrial temperature ranges.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9230BCPZ-210 and AD9230BCPZ-250 are pin-compatible alternatives within the same family offering higher sampling rates of 210 MSPS and 250 MSPS respectively. These may be used if higher bandwidth is needed without changing the PCB footprint. No other direct cross-model replacements are documented in the official datasheet.
