AD9216BCPZ-105

Overview

The AD9216BCPZ-105 is a dual-channel, 10-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 105 MSPS. It features a multistage differential pipelined architecture with output error correction logic to guarantee no missing codes across the full industrial temperature range (-40°C to +85°C). The device operates on a single 3 V supply and includes dual high-performance sample-and-hold amplifiers (SHAs) with a 300 MHz 3 dB bandwidth. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 57.6 dBc and Spurious-Free Dynamic Range (SFDR) of 74 dBc at Nyquist. Power consumption is rated at 150 mW per channel at maximum speed.

Feature Summary

• Dual integrated 10-bit ADCs with independent clock inputs and duty cycle stabilizer for performance maintenance over wide clock variations.
• Differential analog input structure supporting user-selectable input ranges and offsets, including single-ended applications.
• Integrated voltage reference with shared or independent mode selection via control pins.
• Flexible digital output format selectable between offset binary and twos complement.

Applications

• Ultrasound equipment
• IF sampling in communications receivers such as 3G, radio point-to-point, LMDS, and MMDS systems
• Battery-powered instruments and hand-held scopemeters
• Low-cost digital oscilloscopes

Procurement Notes

Verify the specific speed grade suffix matches the required sampling rate, as the AD9216 family includes -65 and -80 variants alongside the -105. Confirm package type is LFCSP-64 and check RoHS compliance status. Ensure the ordering suffix corresponds exactly to the datasheet's Ordering Guide to avoid functional mismatches regarding speed or packaging.

Selection Notes

Select this component when dual-channel conversion is required at speeds up to 105 MSPS with low power constraints. The 10-bit resolution and 3 V single-supply operation suit portable and battery-driven designs. Consider the pin compatibility with AD9238 and AD9248 if future upgrades to higher bit depths are anticipated within the same footprint.

Part Context

The AD9216 belongs to Analog Devices' high-speed data converter portfolio, utilizing an advanced CMOS process. It is designed for applications demanding high linearity and low power in a compact form factor. The device is specified over the industrial temperature range and offers exceptional crosstalk immunity between channels.

Replacement Considerations

The AD9216BCPZ-65 and AD9216BCPZ-80 are pin-compatible alternatives offering lower maximum sampling rates of 65 MSPS and 80 MSPS respectively. These may be suitable if system requirements do not necessitate the full 105 MSPS capability.
