AD9215BCPZ-65

Overview

The AD9215BCPZ-65 is a monolithic, single-supply, 10-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 65 MSPS. It utilizes a multistage differential pipelined architecture with output error correction logic to ensure no missing codes across the full industrial temperature range of −40°C to +85°C. The device features a high-performance sample-and-hold amplifier (SHA) and an internal voltage reference. It operates from a single 3 V analog supply (2.7 V to 3.3 V) and supports digital driver supplies between 2.25 V and 3.6 V. Power consumption is 96 mW at 65 MSPS. The component is housed in a 32-lead LFCSP package.

Feature Summary

• Integrated high-bandwidth differential sample-and-hold amplifier supporting flexible input configurations.
• Built-in clock duty cycle stabilizer to maintain performance under varying clock pulse widths.
• On-chip voltage reference and output error correction logic for accurate data conversion.
• Configurable digital output formats including straight binary and two's complement.

Applications

• Ultrasound equipment
• IF sampling in communications receivers
• Battery-powered instruments
• Hand-held scopemeters
• Low cost digital oscilloscopes

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout compatibility and electrical specifications. Ensure that the required power supply decoupling capacitors are included in the design, as wake-up time depends on these values. Confirm that the application environment remains within the specified industrial temperature limits.

Selection Notes

Select this component when a low-power, 10-bit resolution is required for systems operating up to 65 MSPS. The device is suitable for applications needing a wide dynamic range and flexible analog input ranges. Consider the separate digital supply rail if interfacing with different logic families. Evaluate thermal requirements based on the exposed pad soldering recommendations for the LFCSP package.

Part Context

This part belongs to the AD9215 family of 10-bit ADCs, which also includes variants rated for 80 MSPS and 105 MSPS. The family shares similar architectural features and pinouts, allowing for potential system upgrades or replacements within the same product line. The BC designation indicates the commercial/industrial temperature grade and LFCSP packaging.

Replacement Considerations

Other members of the AD9215 family, such as the AD9215BRUZ-80 or AD9215BRUZ-105, offer higher sampling rates but may require verification of power and timing constraints. Pin-compatible alternatives exist within the broader Analog Devices ADC portfolio, though resolution and speed differences must be evaluated.

FAQ

What is the function of the MODE pin?

The MODE pin selects the data format (straight binary or two's complement) and enables or disables the clock duty cycle stabilizer.

How does the device handle out-of-range signals?

An Out-of-Range (OR) output bit indicates when the signal exceeds the selected input range, which can be used with the MSB to determine overflow direction.

What is the typical aperture jitter specification?

The typical aperture uncertainty (jitter) is 0.5 ps rms.
