AD9467BCPZ-200

Analog To Digital Converters (ADC) Overview

The AD9467BCPZ-200 is a 16-bit, monolithic intermediate frequency sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates at a maximum sampling rate of 200 MSPS and utilizes a pipelined architecture with an integrated input buffer. The device requires dual power supplies: AVDD1/AVDD3 at 1.8 V and AVDD2 at 3.3 V. Typical performance metrics include a signal-to-noise ratio (SNR) of 75.5 dBFS at 210 MHz input and a spurious-free dynamic range (SFDR) of 90 dBFS up to 300 MHz input. Linearity specifications feature typical differential nonlinearity (DNL) of ±0.5 LSB and integral nonlinearity (INL) of ±3.5 LSB. The component is housed in a 72-lead lead-free LFCSP package.

• Broadband wireless communication infrastructure
• Radar systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to confirm the maximum sampling rate specification. Ensure that the supply voltages match the required 1.8 V and 3.3 V rails. Confirm the package type corresponds to the 72-lead LFCSP variant. Check for any environmental compliance certifications required for the target deployment region.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a fixed 200 MSPS sampling rate is sufficient for the application bandwidth requirements. Compare the total power dissipation against thermal constraints if operating near the upper temperature limits. Evaluate the internal reference stability against external precision references if higher accuracy is needed. Consider the pipeline latency of 16 clock cycles for timing-sensitive digital signal processing chains.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9467 family of high-performance IF sampling ADCs. It shares architectural similarities with the AD9467BCPZ-250 variant, which offers a higher 250 MSPS sampling rate. Both devices utilize the same 72-lead LFCSP package and share identical pin configurations and control interfaces, facilitating potential design upgrades or replacements within compatible hardware platforms.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9467BCPZ-250 serves as a direct functional substitute offering increased sampling speed. Verify that the host system clock generation circuitry can support the higher frequency if upgrading to the -250 variant. Ensure that thermal management solutions accommodate any differences in power dissipation profiles between the two models.
