NOTES
1
Gain tests are performed on A
IN
1 over specified input voltage range.
2
Input capacitance specifications show only ceramic package capacitance.
3
Full power bandwidth is the frequency at which the spectral power of the fundamental frequency (as determined by FFT analysis) is reduced by 3 dB.
4
ENCODE driven by single-ended source;
ENCODE
bypassed to ground through 0.01

capacitor.
5
ENCODE may also be driven differentially in conjunction with
ENCODE;
see “Encoding the AD10265” for details.
6
Minimum and maximum conversion rates allow for variation in Encode Duty Cycle of 50%
±
5%.
7
Analog Input signal power at –1 dBFS; signal-to-noise ratio (SNR) is the ratio of signal level to total noise (first 5 harmonics removed). Encode = 65 MSPS.
8
Analog Input signal power at –1 dBFS; signal-to-noise and distortion (SINAD) is the ratio of signal level to total noise + harmonics. Encode = 65 MSPS.
9
Analog Input signal equal –1 dBFS; SFDR is ratio of converter full scale to worst spur.
10
Both input tones at –7 dBFS; two-tone intermodulation distortion (IMD) rejection is the ratio of either tone to the worst third order intermod product. f1 = 17.0 MHz
±

Absolute maximum ratings are limiting values to be applied individually, and
beyond which the serviceability of the circuit may be impaired. Functional
operability is not necessarily implied. Exposure to absolute maximum rating
conditions for an extended period of time may affect device reliability.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD10265 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.
