PRODUCT DESCRIPTION
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 sur-
face-mount plastic package (28-lead SSOP) and is specified over
the industrial temperature range.
