Overview
The AD9239BCPZ-170 is a high-performance, quad 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This device is designed to handle high-frequency, wide dynamic range signals with an input bandwidth up to 780 MHz. It features four ADCs in a single package, making it ideal for applications requiring multiple channels of high-speed data conversion.
The AD9239BCPZ-170 operates from a single 1.8 V power supply and supports various clock input types, including differential sine wave, LVPECL, TTL, and LVDS. The device includes a clock duty cycle stabilizer to ensure high performance across a wide range of clock duty cycles. Additionally, it has an on-chip reference that can be adjusted via SPI control, eliminating the need for external decoupling.
