1 Gain tests are performed on AIN3 over specified input voltage range.
2 Input capacitance specifications combines AD9631 die capacitance + 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 (Pin 4) driven by single-ended source; ENCODE (Pin 5) bypassed to ground through 0.01 µF capacitor.
5 ENCODE (Pin 4) may also be driven differentially in conjunction with ENCODE (Pin 5); see “Encoding the AD10242” 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 = 40.0 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 = 40.0 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 3rd order intermod product. f1 = 10.0 MHz
± 100 kHz, 50 kHz ≤ f1 – f2 ≤ 300 kHz.
11 Channel-to-channel isolation tested with A channel grounded and a full-scale signal applied to B channel (AIN1).
12 Input driven to 2× and 4× AIN1 range for >4 clock cycles. Output recovers inband in specified time with Encode = 40 MSPS. No foldover guaranteed.
13 Outputs are sourcing 10 µA.
14 Outputs are sinking 10 µA.
All specifications guaranteed within 100 ms of initial power up regardless of sequencing.
Specifications subject to change without notice.
