AD9059BRS

Overview

The AD9059BRS is a dual-channel, 8-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates with a maximum sampling rate of 60 MSPS and features a typical full-power analog bandwidth of 120 MHz. The device integrates an internal 2.5 V voltage reference and dual track-and-hold circuits, requiring only a single 5 V analog supply and a 3 V to 5 V digital supply. Key electrical specifications include a Signal-to-Noise Ratio (SNR) of 46 dB at 10.3 MHz input frequency, a Differential Nonlinearity (DNL) of 2.5 LSB, and an Integral Nonlinearity (INL) of 2.5 LSB across the full temperature range. Typical power dissipation is 400 mW, which reduces to less than 12 mW in power-down mode.

Feature Summary

• Dual independent 8-bit ADC channels on a single monolithic chip
• Integrated 2.5 V bandgap voltage reference and track-and-hold circuits
• Simultaneous sampling capability controlled by a single encode clock
• Low power consumption with dedicated power-down mode functionality

Applications

• Digital communications including QAM demodulators
• RGB and YC/Composite video processing systems
• Digital data storage read channels
• Medical imaging equipment
• Digital instrumentation

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific ordering suffix matches the required package type and temperature rating. Request official datasheets and test reports to validate performance parameters against application requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring synchronized dual-channel digitization with moderate resolution and high speed. Ensure the system design accommodates the 1 V p-p single-ended input range centered at 2.5 V. Consider the AD9057 if only a single channel is needed, as it utilizes the same core architecture but in a smaller 20-lead package.

Part Context

The AD9059 belongs to the AD9059 family of dual 8-bit ADCs from Analog Devices. It is fabricated using an advanced BiCMOS process technology. The device is housed in a 28-lead shrink small outline package (SSOP). It is designed to offer a balance between cost, power efficiency, and dynamic performance for general-purpose high-speed data acquisition tasks.

Replacement Considerations

The AD9057 serves as a single-channel alternative based on the same ADC core architecture.
