AD9215BRUZ-105

Overview

The AD9215BRUZ-105 is a monolithic, single-supply, 10-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 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 (SHA) and an on-chip voltage reference. It operates from a single 3 V analog supply (2.7 V to 3.3 V) and a separate digital driver supply (2.25 V to 3.6 V). At 105 MSPS, the core ADC consumes 120 mW. The component is housed in a 28-lead TSSOP surface-mount package.

Feature Summary

• Multistage differential pipelined architecture with output error correction logic for guaranteed 10-bit accuracy without missing codes.
• Wide bandwidth, truly differential sample-and-hold amplifier (SHA) supporting flexible analog input ranges and offsets.
• Integrated clock duty cycle stabilizer to maintain performance over wide variations in clock pulse widths.
• On-chip reference voltage source and sample-and-hold amplifier reducing external component requirements.

Applications

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

Procurement Notes

Verify the specific suffix '-105' to confirm the 105 MSPS speed grade, as the AD9215 family includes 65 MSPS and 80 MSPS variants. Ensure the ordering suffix 'RUZ' corresponds to the 28-lead TSSOP package with RoHS compliance. Confirm that the required logic levels match the DRVDD supply range of 2.25 V to 3.6 V for your system interface.

Selection Notes

Select this model when a 105 MSPS sampling rate is required for direct IF sampling or high-bandwidth applications. Consider the 1 V p-p to 2 V p-p flexible analog input span and the internal reference options. Verify that the 120 mW power consumption at maximum speed fits within the thermal budget of the 28-TSSOP package. Check compatibility with offset binary or two's complement data formats via the MODE pin configuration.

Part Context

The AD9215BRUZ-105 belongs to the AD9215 family of low-power, 10-bit ADCs manufactured by Analog Devices Inc. This family shares architectural similarities with other pin-compatible devices in the series, allowing for potential upgrades to higher resolutions in systems operating up to 80 MSPS. The BRU designation indicates the industrial temperature grade and TSSOP packaging.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should verify pinout and electrical parameter compatibility if considering alternative manufacturers or different speed grades within the same package type.
