Description
The AD9238BSTZ-40 is a 12-bit, 40 MSPS (Mega Samples Per Second) analog-to-digital converter (ADC) from Analog Devices. It features low power consumption (72 mW at 40 MSPS) and a high-performance sampling pipeline architecture, making it suitable for applications like communications, medical imaging, and instrumentation.
Key features:
- 12-bit resolution with SNR (Signal-to-Noise Ratio) of 70.5 dB at 10 MHz input.
- Differential input with a 1 Vp-p to 2 Vp-p adjustable range.
- LVDS (Low-Voltage Differential Signaling) or CMOS output options.
- Internal reference voltage with external reference support.
- 3.3 V single-supply operation.
The BSTZ package is a 48-lead LQFP, ensuring compact PCB integration. Its low power and high speed make it ideal for portable and high-speed data acquisition systems.
