AD9237BCPZRL7-40

Overview

The AD9237BCPZRL7-40 is a monolithic, single-supply, 12-bit analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum sampling rate of 40 MSPS with ultralow power consumption of 135 mW. The device features a differential input with 500 MHz bandwidth and supports flexible input ranges from 1 V p-p to 4 V p-p. It utilizes a multistage differential pipelined architecture with output error correction logic to guarantee no missing codes over the full operating temperature range of −40°C to +85°C. The ADC includes an internal voltage reference, clock duty cycle stabilizer, and two-step power-down modes.

Feature Summary

• Ultralow power consumption scales with speed, consuming 135 mW at 40 MSPS.
• Patented sample-and-hold amplifier maintains performance for input frequencies beyond Nyquist.
• Flexible analog input configuration allows selectable ranges from 1 V p-p to 4 V p-p.
• Integrated clock duty cycle stabilizer ensures consistent performance across varying clock pulse widths.

Applications

• Ultrasound and medical imaging systems
• Battery-powered instruments
• Hand-held scope meters
• Low cost digital oscilloscopes
• Low power communications

Procurement Notes

Verify the specific ordering suffix RL7 indicates reel packaging when confirming procurement details. Ensure the component matches the AD9237BCP-40 specification for 40 MSPS operation. Confirm that the package type corresponds to the 32-lead LFCSP as documented in the official datasheet. Cross-reference the manufacturer part number with authorized distribution channels to ensure authenticity.

Selection Notes

Select this model for applications requiring 12-bit resolution at 40 MSPS with minimal power dissipation. The separate DRVDD supply accommodates both 2.5 V and 3.3 V logic families. Consider the 9-cycle pipeline latency when designing timing-critical interfaces. The device supports offset binary, twos complement, or gray code data formats via mode selection pins.

Part Context

The AD9237 family includes variants optimized for 20 MSPS, 40 MSPS, and 65 MSPS speeds. The BCPZRL7-40 designation identifies the 40 MSPS version in a lead-free LFCSP package supplied on a reel. This component belongs to a series designed for imaging and medical ultrasound applications where power efficiency is critical compared to previous generations.

Replacement Considerations

The AD9237BCPZRL7-20 serves as a lower-speed alternative within the same family. The AD9237BCPZRL7-65 offers higher throughput at increased power consumption. All variants share the same pinout and architectural features, facilitating direct substitution if speed requirements change.
