This document describes the features and characteristics of the AD9215, a 10-bit, 65/80/105 MSPS, 3V A/D converter from Analog Devices. The product operates on a single 3V supply and features a SNR of 58 dBc, SFDR of 77 dBc, and a low power ADC core. It is suitable for applications such as ultrasound equipment, IF sampling in communications receivers, battery-powered instruments, and low-cost digital oscilloscopes.
The AD9215 family of monolithic analog‑to‑digital converters operates from a single 3 V supply (2.7 V to 3.3 V) and provides 10‑bit resolution at conversion rates of 65, 80 or 105 MSPS. It features a high‑performance sample‑and‑hold amplifier, on‑chip reference, clock‑duty‑cycle stabilizer and flexible input ranges, making it suitable for ultrasound, communications receivers, hand‑held instruments and low‑cost oscilloscopes.
Key specifications include a typical SNR of 58 dB, ENOB of up to 9.5 bits, 300 MHz analog bandwidth, and power consumption as low as 96 mW at 65 MSPS and 120 mW at 105 MSPS. The device is offered in 28‑lead TSSOP and 32‑lead LFCSP packages and is rated for industrial temperature operation from –40 °C to +85 °C.
