AD9057BRSZ-RL60

Overview

The AD9057BRSZ-RL60 is an 8-bit monolithic analog-to-digital converter (ADC) optimized for low cost, low power, and small size. It features a full-power analog bandwidth of 120 MHz and supports encode rates up to 60 MSPS. The device integrates an internal 2.5 V reference and a track-and-hold circuit, requiring only a single 5 V supply and an encode clock. It operates with TTL/CMOS compatible inputs and supports 3 V or 5 V logic interfaces. Power consumption is typically 205 mW at 60 MSPS and drops below 10 mW in power-down mode. The component is housed in a 20-lead SSOP package and specified over the 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.
• Features a MagAmp/Flash architecture providing 8-bit accuracy with low power dissipation and high conversion speeds.
• Supports flexible digital interface compatibility with both 3 V and 5 V logic systems via isolated digital supply pin.

Applications

• Digital Communications including QAM demodulators
• RGB and YC/Composite Video Processing
• Medical Imaging Systems

Procurement Notes

Verify the specific performance grade corresponds to the required maximum sampling rate, as the AD9057 family includes 40 MSPS, 60 MSPS, and 80 MSPS variants. Confirm that the RS-20 package option matches the PCB footprint requirements. Ensure the ordering suffix aligns with the desired reel quantity and packaging format before finalizing procurement orders.

Selection Notes

Select this model when a balance of moderate resolution and high speed is required for direct IF sampling applications. Consider the integrated reference capability if system complexity must be reduced. Evaluate the 120 MHz analog bandwidth against the Nyquist frequency of the input signal to ensure adequate dynamic performance without excessive anti-aliasing filtering.

Part Context

This component belongs to the AD9057 series of 8-bit ADCs, which also includes grades rated for 40 MSPS and 80 MSPS. It shares the same physical package and pinout with the AD9059, a dual-channel variant based on the same core technology. The device utilizes Analog Devices' proprietary MagAmp gray code conversion circuitry combined with flash converter technology.
