Rohs Status
RoHS non-compliant
PRODUCT DESCRIPTION
The AD9059 is a dual 8-bit monolithic analog-to-digital converter
optimized for low cost, low power, small size, and ease of use.
With a 60 MSPS encode rate capability and full-power analog
bandwidth of 120 MHz typical, the component is ideal for
applications requiring multiple ADCs with excellent dynamic
performance.
To minimize system cost and power dissipation, the AD9059
includes an internal 2.5 V reference and dual track-and-hold
circuits. The ADC requires only a 5 V power supply and an
encode clock. No external reference or driver components are
required for many applications.
The AD9059’s single encode input is TTL/CMOS compatible
and simultaneously controls both internal ADC channels. The
parallel 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 <12 mW when ADC data is not required
for lengthy periods of time. In power-down mode, the digital
outputs are driven to a high impedance state.
Fabricated on an advanced BiCMOS process, the AD9059
is available in a space-saving 28-lead shrink small outline
package (28-lead SSOP) and is specified over the industrial
temperature range (–40°C to +85°C).
Customers desiring single-channel digitization may consider the
AD9057, a single 8-bit, 60 MSPS monolithic based on the
AD9059 ADC core. The AD9057 is available in a 20-lead shrink
small outline package (20-lead SSOP) and is specified over the
industrial temperature range.
