Overview
The AD9215BRUZ-105, produced by Analog Devices Inc., is a high-performance, 10-bit analog-to-digital converter (ADC) that operates from a single 3 V power supply. This ADC is part of the AD9215 family, which features a multistage differential pipelined architecture with output error correction logic. It is designed to provide 10-bit accuracy at sampling rates of up to 105 MSPS and ensures no missing codes over the full operating temperature range of −40°C to +85°C. The device is fabricated on an advanced CMOS process and is available in both 28-lead TSSOP and 32-lead chip scale packages.
