AD9626BCPZ-170

Analog To Digital Converters (ADC) Overview

The AD9626BCPZ-170 is a 12-bit monolithic sampling analog-to-digital converter (ADC) from Analog Devices, optimized for high performance and low power consumption. It operates at a maximum conversion rate of 170 MSPS with a 700 MHz full-power analog bandwidth. The device features an integrated track-and-hold amplifier and voltage reference, requiring only a single 1.8 V supply for both analog and digital sections. It offers selectable output data formats including offset binary, two's complement, and Gray code, alongside a programmable input voltage range of 1.0 V to 1.5 V. Fabricated on an advanced CMOS process, it is housed in a 56-lead LFCSP package and specified over the industrial temperature range of −40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated track-and-hold amplifier and internal voltage reference eliminate the need for external decoupling components.
• Supports flexible interface options with CMOS outputs and selectable data formats such as offset binary, two's complement, and Gray code.
• Includes a clock duty cycle stabilizer and integrated data capture clock for simplified timing management.
• Features a standard serial port interface for configuration of functions like gain adjustment, power-down modes, and test pattern generation.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCPZ corresponds to the 170 MSPS speed grade when ordering. Confirm that the 56-lead LFCSP package requirements align with your PCB layout capabilities, particularly regarding the exposed paddle soldering for thermal management. Ensure that the 1.8 V supply rails meet the absolute maximum rating limits to prevent device damage during operation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and up to 170 MSPS sampling rate are required for wideband signal processing. Consider the AD9626 family if pin compatibility with the 10-bit AD9601 is needed for future design flexibility. Evaluate the low power dissipation characteristics against system thermal constraints, noting that power scales with the sample rate. Verify that the differential input requirements match your front-end driver capabilities.

Analog To Digital Converters (ADC) Part Context

The AD9626 series includes variants operating at 170 MSPS, 210 MSPS, and 250 MSPS, all sharing the same 56-lead LFCSP package and functional architecture. The BC prefix typically denotes the industrial temperature grade variant within the product line. This part belongs to a family designed for ease of use with FPGA interfaces, offering a complete signal conversion solution with on-chip references and buffers.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9626BCPZ-210 and AD9626BCPZ-250 are pin-compatible upgrades offering higher sampling rates. For lower resolution needs, the AD9601 provides a pin-compatible 10-bit alternative. Ensure that any replacement maintains the 1.8 V supply requirement and LFCSP package footprint for direct board integration.
