The AD9057 is an 8-bit monolithic analog-to-digital converter optimized for low cost, low power, small size, and ease of use. With 40 MSPS, 60 MSPS, or 80 MSPS encode rate capability and full-power analog bandwidth of 120 MHz, the component is ideal for applications requiring excellent dynamic performance. To minimize system cost and power dissipation, the AD9057 includes an internal 2.5 V reference and a track-and-hold (T/H) circuit. The user must provide only a 5 V power supply and an encode clock. No external reference or driver components are required for many applications. The AD9057’s encode input is TTL/CMOS compatible, and the 8-bit digital outputs can be operated from 5 V or 3 V supplies.
The AD9057 is an 8‑bit monolithic analog‑to‑digital converter optimized for low cost, low power, and small size. It supports three performance grades (40 MSPS, 60 MSPS, 80 MSPS) with a full‑power analog bandwidth of 120 MHz, a single 5 V supply, and selectable 3 V or 5 V logic levels.
Typical applications include digital communications, video processing, medical imaging, and high‑speed instrumentation. An evaluation board (AD9057/PCB) provides a complete reference design with optional analog input buffering, digital output latching, and configurable jumpers for AC/DC coupling and power‑down testing.
