AD9233BCPZRL7-125

Overview

The AD9233BCPZRL7-125 is a monolithic, single 1.8 V supply, 12-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 125 MSPS. It features a high-performance sample-and-hold amplifier (SHA) and an on-chip voltage reference. The device utilizes a multistage differential pipeline architecture with output error correction logic to ensure 12-bit accuracy and guarantees no missing codes over the full industrial temperature range (-40°C to +85°C). Key electrical specifications include a signal-to-noise ratio (SNR) of 69.5 dBc at 70 MHz input, a spurious-free dynamic range (SFDR) of 85 dBc, and a power consumption of 395 mW at maximum speed. The part is housed in a 48-lead LFCSP package.

Feature Summary

• Multistage differential pipeline architecture with output error correction logic for 12-bit accuracy
• High-performance truly differential sample-and-hold amplifier (SHA) with 650 MHz bandwidth
• Integrated on-chip voltage reference and flexible analog input ranges
• Built-in clock duty cycle stabilizer (DCS) and programmable data alignment

Applications

• Ultrasound equipment
• IF sampling in communications receivers
• Battery-powered instruments
• Hand-held scopemeters

Procurement Notes

Verify the specific ordering suffix RL7 confirms the reel packaging format when sourcing from distributors. Confirm that the -125 designation matches the required 125 MSPS conversion rate for the target design. Ensure the LFCSP-48 thermal pad soldering requirements are met during assembly to maintain specified thermal resistance and reliability.

Selection Notes

Select this component when a low-power, single-supply 12-bit ADC is required for high-speed applications up to 125 MSPS. The integrated SHA and voltage reference simplify front-end design compared to discrete solutions. Consider the pin compatibility with the 14-bit AD9246 if future migration to higher resolution is anticipated within the same form factor.

Part Context

The AD9233 series includes variants optimized for different throughput requirements: 80 MSPS, 105 MSPS, and 125 MSPS. The AD9233BCPZ-125 represents the highest performance tier within this family, designed for applications demanding maximum sampling rates while maintaining low power consumption and high linearity metrics across the industrial temperature range.

Replacement Considerations

The AD9233BCPZ-105 and AD9233BCPZ-80 are pin-compatible lower-speed alternatives within the same package. For designs requiring higher resolution, the AD9246 series offers a pin-compatible migration path to 14-bit performance.
