NOTES

1 All ac specifications tested by driving ENCODE and

ENCODE differentially. Single-ended input: AMP-IN-X-1 = 1 V p-p, AMP-IN-X-2 = GND.

2 Gain tests are performed on AMP-IN-X-1 input voltage range.

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 For differential input: +IN = 1 V p-p and –IN = 1 V p-p (signals are 180

° out of phase). For single-ended input: +IN = 2 V p-p and = –IN = GND.

5 Minimum and maximum conversion rates allow for variation in Encode Duty Cycle of 50%

± 5%.

6 Analog Input signal power at –1 dBFS; signal-to-noise ratio (SNR) is the ratio of signal level to total noise (first five harmonics removed). Encode = 80 MSPS. SNR

is reported in dBFS, related back to converter full scale.

7 Analog Input signal power at –1 dBFS; signal-to-noise and distortion (SINAD) is the ratio of signal level to total noise + harmonics. Encode = 80 MSPS. SINAD is

reported in dBFS, related back to converter full scale.

8 Analog Input signal at –1 dBFS; SFDR is ratio of converter full scale to worst spur.

9 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.

10Channel-to-channel isolation tested with A channel grounded and a full-scale signal applied to B Channel.

11 Digital output logic levels: DV

CC = 3.3 V, CLOAD = 10 pF. Capacitive loads > 10 pF will degrade performance.

12 Supply voltage recommended operating range. AV

CC may be varied from 4.85 V to 5.25 V. However, rated ac (harmonics) performance is valid only over the range

AVCC = 5.0 V to 5.25 V.

Specifications subject to change without notice.
