PRODUCT DESCRIPTIONThe 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 capabil-
ity 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 consump-
tion 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 pack-
age (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 sur-
face mount plastic package (28 SSOP) and is specified over the
industrial temperature range.

PIN CONFIGURATION
AD9057–SPECIFICATIONS(VD = 5 V, VDD = 3 V; external reference, unless otherwise noted.)
AD9057NOTESGain error and gain temperature coefficient are based on the ADC only (with a fixed 2.5 V external reference).tV and tPD are measured from the 1.5 V level of the ENCODE to the 10%/90% levels of the digital output swing. The digital output load during test is not to exceed
an ac load of 10 pF or a dc current of ±40 µA.SNR/harmonics based on an analog input voltage of –0.5 dBFS referenced to a 1.0 V full-scale input range.Digital supply current based on VDD = 3 V output drive with <10 pF loading under dynamic test conditions.Power dissipation is based on specified encode and 10.3 MHz analog input dynamic test conditions (VD = 5 V ±5%, VDD = 3 V ±5%).Typical thermal impedance for the RS style (SSOP) 20-lead package:θJC = 46°C/W, θCA = 80°C/W, θJA = 126°C/W.

EXPLANATION OF TEST LEVELS
AD9057
CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD9057 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
