AD9246BCPZRL7-125

Overview

The AD9246BCPZRL7-125 is a monolithic, single 1.8 V supply, 14-bit analog-to-digital converter (ADC) with a maximum sampling rate of 125 MSPS. It features a high-performance sample-and-hold amplifier and an on-chip voltage reference. The device utilizes a multistage differential pipeline architecture with output error correction logic to ensure 14-bit accuracy at full speed and guarantees no missing codes across the operating temperature range. It operates from a single 1.8 V analog supply and supports 1.8 V to 3.3 V digital output drivers.

Feature Summary

• Multistage differential pipeline architecture with output error correction logic for 14-bit accuracy
• Integrated sample-and-hold amplifier and on-chip voltage reference
• Flexible analog input supporting offset binary, Gray code, or twos complement data formats
• Clock duty cycle stabilizer to maintain performance over wide clock pulse width variations

Applications

• Ultrasound equipment
• IF sampling in communications receivers
• IS-95, CDMA-One, IMT-2000 systems
• Battery-powered instruments
• Hand-held scopemeters

Procurement Notes

Verify the specific speed grade suffix (-125) matches the required 125 MSPS conversion rate. Confirm the LFCSP_VQ package type and lead-free status associated with the BCPZ designation. Ensure the RL7 reel packaging requirement aligns with automated assembly processes. Cross-reference the ordering guide for any regional compliance markings.

Selection Notes

Select this component when a 14-bit resolution and 125 MSPS throughput are required within a low-power constraint. The integrated reference eliminates external components, simplifying board layout. Consider the 1.8 V analog supply and separate digital driver supply for interface compatibility with downstream logic families ranging from 1.8 V to 3.3 V.

Part Context

The AD9246 series includes variants optimized for different sampling rates, specifically 80 MSPS, 105 MSPS, and 125 MSPS. The -125 suffix denotes the highest speed grade within this family. All variants share the same pinout and architectural features, allowing for design flexibility based on bandwidth requirements while maintaining consistent software and hardware integration.

Replacement Considerations

The AD9246 is pin-compatible with the AD9233, facilitating migration from 12-bit to 14-bit designs. No direct single-channel 14-bit replacements with identical pinouts are documented in the provided datasheet.
