Overview

Description

The AD9243ASZRL is a 14-bit, 3 MSPS analog-to-digital converter (ADC) from Analog Devices, designed for precision signal acquisition. It features a high dynamic range, low power consumption (~50 mW at 3 MSPS), and a flexible input range (up to ±2.25V differential).
Key highlights:
- Resolution/Speed: 14-bit at 3 MSPS.
- Input Range: Adjustable (1Vp-p to 2.25Vp-p differential).
- Low Power: Optimized for portable and power-sensitive applications.
- Integrated Features: On-chip sample-and-hold, reference buffer, and optional dither.
- Interface: Parallel CMOS output.
- Package: 44-lead LQFP (ASZRL denotes tape-and-reel packaging).
Ideal for medical imaging, communications, and industrial instrumentation requiring high accuracy at moderate speeds.

Equivalent

The AD9243ASZRL is a 14-bit, 40 MSPS ADC. Equivalent alternatives include:
1. AD9244 (14-bit, 65 MSPS)
2. AD9643 (14-bit, 80/105/125 MSPS)
3. LTC2208 (16-bit, 130 MSPS, higher resolution)
4. ADS4149 (14-bit, 250 MSPS, faster)
Check pin compatibility and specs for exact replacement. For lower speed, AD9240 (10-bit, 40 MSPS) may work if resolution is flexible.
