Visão Geral

Description

The AD9235BRUZ-65 is a 12-bit, 65 MSPS (Mega Samples Per Second) analog-to-digital converter (ADC) from Analog Devices. It features low power consumption (typically 185 mW at 65 MSPS) and a high-performance sampling pipeline architecture, making it suitable for communications, medical imaging, and industrial applications.
Key features include:
- 12-bit resolution with 65 MSPS sampling rate
- 1.8V single-supply operation
- LVDS (Low-Voltage Differential Signaling) or CMOS output options
- SNR (Signal-to-Noise Ratio) of 70.5 dB at 10 MHz input
- Flexible input range (1 Vp-p to 2 Vp-p differential)
The device comes in a TSSOP-32 package and supports clock duty cycle stabilization, ensuring reliable performance. Its low power and high speed make it ideal for portable and high-speed data acquisition systems.
