AD9215BCPZ-105

Overview

The AD9215BCPZ-105 is a monolithic, single 3 V supply, 10-bit analog-to-digital converter operating at 105 MSPS. It utilizes a multistage differential pipelined architecture with output error correction logic to guarantee 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 and an on-chip voltage reference. It operates from a single AVDD supply (2.7 V to 3.3 V) and a separate DRVDD supply (2.25 V to 3.6 V). At 105 MSPS, the core ADC consumes 120 mW. Key specifications include a signal-to-noise ratio of 58 dBc and a spurious-free dynamic range of 77 dBc.

Feature Summary

• Multistage differential pipelined architecture with digital output error correction logic for guaranteed linearity.
• Wide bandwidth, truly differential sample-and-hold amplifier supporting flexible input ranges.
• Integrated clock duty cycle stabilizer to maintain performance under varying clock pulse widths.
• On-chip voltage reference and offset binary or twos complement data format options.

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 package type and speed grade. Ensure that the component matches the required industrial temperature range and power supply specifications for the target application environment before finalizing procurement.

Selection Notes

Select this model when a 10-bit resolution and 105 MSPS sampling rate are required within a low-power, single-supply design. Consider the 32-lead LFCSP package for space-constrained layouts requiring efficient thermal dissipation. Verify compatibility with the system's logic voltage levels via the separate DRVDD pin.

Part Context

This component belongs to the AD9215 family of low-power, 10-bit analog-to-digital converters. The family includes variants optimized for different maximum conversion rates, specifically 65 MSPS and 80 MSPS, alongside the 105 MSPS version. All members share the same functional architecture and pinout configuration.
