AD9233BCPZRL7-105

Overview

The AD9233BCPZRL7-105 is a monolithic, single 1.8 V supply, 12-bit, 105 MSPS analog-to-digital converter (ADC) featuring a high-performance sample-and-hold amplifier and on-chip voltage reference. It utilizes a multistage differential pipeline architecture with output error correction logic to provide 12-bit accuracy at 105 MSPS data rates. The device guarantees no missing codes over the full operating temperature range of −40°C to +85°C. Key electrical parameters include an SNR of 69.5 dBc at 70 MHz input, SFDR of 85 dBc, DNL of ±0.15 LSB, and INL of ±1.2 LSB. Power consumption is 350 mW at maximum sample rate with DC input.

Feature Summary

• Multistage differential pipeline architecture with output error correction logic for 12-bit accuracy
• On-chip voltage reference and high-performance sample-and-hold amplifier
• Flexible analog input supporting 1 V p-p to 2 V p-p ranges
• Built-in selectable digital test pattern generation and programmable clock/data alignment

Applications

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

Procurement Notes

Verify the specific ordering suffix RL7 against official Analog Devices documentation to confirm reel packaging specifications. Ensure compatibility with required logic families by checking DRVDD voltage requirements. Confirm that the 105 MSPS speed grade meets system timing constraints. Validate thermal performance within the specified industrial temperature range during integration.

Selection Notes

Select this component when a 12-bit resolution and 105 MSPS sampling rate are required within a low-power 1.8 V environment. Consider the AD9233BCPZ-125 if higher throughput is needed, or the AD9233BCPZ-80 for lower power applications. Evaluate the need for the internal voltage reference versus external precision references based on system noise requirements.

Part Context

The AD9233 series includes variants with different maximum sampling rates: 80 MSPS, 105 MSPS, and 125 MSPS. All variants share the same pinout and architectural features, allowing for design flexibility across different bandwidth requirements while maintaining compatibility with the 48-lead LFCSP package.

Replacement Considerations

The AD9233 is pin-compatible with the AD9246, which offers 14-bit resolution. Direct substitution requires verifying that the increased resolution does not impact power budgets or signal chain requirements.
