The AD9058AJD is a dual-channel, 8-bit, 50 MSPS (Mega Samples Per Second) analog-to-digital converter (ADC) manufactured by Analog Devices, Inc. (ADI).

This device integrates two independent high-performance 8-bit ADCs on a single monolithic IC, designed for applications requiring simultaneous sampling of two analog signals. It offers a cost-effective solution by replacing two discrete ADCs with a single chip, available in a 48-CDIP (Ceramic Dual In-line Package).

The AD9058AJD performs high-speed analog-to-digital conversion. Each of its two ADC channels can sample an analog input signal at rates up to 50 million times per second, converting the instantaneous voltage into an 8-bit digital value.

Its flash architecture enables these high-speed conversions. The device features:

• Low input capacitance, minimizing loading on the input signal source
• Internal reference voltage for simplified system design
• Option for external reference voltage
• Parallel digital outputs compatible with TTL logic levels

This ADC is suitable for applications requiring dual-channel, high-speed data acquisition. Common use cases include:

• Quadrature Demodulation in communication systems
• Digital Oscilloscopes
• Medical Imaging Equipment
• Radar and Sonar Signal Processing
• Industrial Automation and control systems requiring simultaneous measurement of multiple signals
