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. 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 shrink small outline package (20-lead SSOP) and is specified over the industrial temperature range (–40∞C to +85∞C)。 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-lead SSOP) and is specified over the industrial temperature range.
