AD9243ASZ

The AD9243ASZ is a complete single-chip 14-bit, 3 MSPS analog-to-digital converter (ADC) from Analog Devices. It employs a pipelined architecture with an on-chip sample-and-hold amplifier and voltage reference, providing excellent AC and DC performance. Key specifications include a typical signal-to-noise and distortion ratio (SINAD) of 79.0 dB and spurious-free dynamic range (SFDR) of 91.0 dB. DC accuracy is characterized by integral nonlinearity (INL) of 2.5 LSB and differential nonlinearity (DNL) of 0.6 LSB. The input can be configured for either single-ended or differential signals, offering flexibility in analog interface design.

The ADC operates from a single +5 V analog supply and dissipates only 110 mW of power, making it suitable for power-sensitive applications. The parallel data interface simplifies connection to digital signal processors or FPGAs. The device is specified over the industrial temperature range of -40°C to 85°C. It is available in a 44-lead MQFP (10x10 mm) surface mount package, ideal for compact PCB layouts. The AD9243ASZ is designed for applications requiring high resolution and moderate sampling rates, such as medical imaging, communications, and industrial data acquisition.
