power-down function may be exercised to bring total consumption The AD9057 is an 8-bit monolithic analog-to-digital converter to <10 mW. In power-down mode, the digital outputs are driven optimized for low cost, low power, small size, and ease of use. to a high impedance state. With 40 MSPS, 60 MSPS, or 80 MSPS encode rate capability Fabricated on an advanced BiCMOS process, the AD9057 is and full-power analog bandwidth of 120 MHz, the component is available in a space-saving 20-lead shrink small outline package ideal for applications requiring excellent dynamic performance. (20-lead SSOP) and is specified over the industrial temperature To minimize system cost and power dissipation, the AD9057 range (–40∞C to +85∞C). includes an internal 2.5 V reference and a track-and-hold (T/H) Customers desiring multichannel digitization may consider the circuit. The user must provide only a 5 V power supply and an AD9059, a dual 8-bit, 60 MSPS monolithic based on the encode clock. No external reference or driver components are AD9057 ADC core. The AD9059 is available in a 28-lead sur- required for many applications. face-mount plastic package (28-lead SSOP) and is specified over The AD9057’s encode input is TTL/CMOS compatible, and the the industrial temperature range. 8-bit digital outputs can be operated from 5 V or 3 V supplies.
