AD9057BRSZ-60

Overview

The AD9057BRSZ-60 is an 8-bit monolithic analog-to-digital converter (ADC) from Analog Devices, operating at a maximum sampling rate of 60 MSPS. It features a full-power analog bandwidth of 120 MHz and utilizes a pipeline architecture combining MagAmp gray code conversion with flash technology. The device includes an internal 2.5 V reference and track-and-hold circuit, requiring only a single 5 V analog supply and a TTL/CMOS compatible encode clock. Digital outputs support 3 V or 5 V logic interfaces via the VDD pin. Typical power dissipation is 205 mW, reducing to under 10 mW in power-down mode. It is housed in a 20-lead SSOP package and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates an on-chip 2.5 V voltage reference and high-speed track-and-hold circuit to minimize external component requirements.
• Combines proprietary MagAmp gray code conversion with flash converter architecture for optimized low power and high speed performance.
• Supports flexible digital logic interfacing with both 3 V and 5 V CMOS systems through an isolated digital supply pin.

Applications

• Digital Communications (QAM Demodulators)
• RGB and YC/Composite Video Processing
• Medical Imaging

Procurement Notes

Verify the specific grade suffix (-60) corresponds to the required 60 MSPS encoding rate during procurement. Confirm the RS-20 SSOP package option matches the target PCB footprint. Ensure the industrial temperature range specification aligns with the operational environment constraints of the final design application.

Selection Notes

Select this model when a single-channel 8-bit ADC with 60 MSPS throughput is required. Consider the AD9059 if dual-channel digitization is necessary. Evaluate the need for external versus internal reference accuracy based on system gain requirements. Verify that the 1 V p-p input range and 150 kΩ input impedance are compatible with the source signal characteristics.

Part Context

This component belongs to the AD9057 family of low-cost, low-power 8-bit ADCs. It shares the same core architecture as the AD9057BRS-40 (40 MSPS) and AD9057BRS-80 (80 MSPS), differentiated primarily by its maximum encoding rate. The AD9059 serves as the dual-channel counterpart within the same product line.

Replacement Considerations
