概要

Description

The AD9245BCPZ-20 is a 14-bit, 20 MSPS (Mega Samples Per Second) analog-to-digital converter (ADC) from Analog Devices. It features low power consumption (72 mW at 20 MSPS) and a high-performance pipeline architecture, making it suitable for applications like communications, medical imaging, and instrumentation.
Key features:
- 14-bit resolution with SNR of 74 dB (typical).
- Differential input with a 1 Vp-p full-scale range.
- LVDS (Low-Voltage Differential Signaling) or CMOS output options.
- 3.3 V single-supply operation.
- Internal reference and sample-and-hold circuit.
Packaged in a 32-lead LFCSP (5x5 mm), it offers compact integration. The AD9245BCPZ-20 is ideal for systems requiring high-speed, precision data conversion with minimal power consumption.
