AD9057:  8-Bit, 40/60/80 MSPS A/D Converter

Product Details

The AD9057 is an 8-bit monolithic analog-to-digital converter optimized for low cost, low power, small size, and ease of use. With a 40 MSPS, 60 MSPS or 80 MSPS encode rates 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 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. A power-down function may be exercised to bring total consumption to < 10 mW. In power-down mode the digital outputs are driven to a high impedance state.

Fabricated on an advanced BiCMOS process, the AD9057 is available in a space saving 20-lead surface mount plastic package (20 SSOP) and is specified over the industrial (-40°C to +85°C) temperature range.

Customers desiring multichannel digitization may consider the AD9059, a dual 8-bit, 60 MSPS monolithic based on the AD9057 ADC core. The AD9059 is available in a 28-lead surface mount plastic package (28 SSOP) and is specified over the industrial temperature range.
