F capacitor between the COMP and AVDD terminal; with a 0.1
μ
F capacitor connected between the VREF terminal and
AVSS. The ripple amplitude is within the range 100 mVp-p to 500 mVp-p with the DAC output set to full scale and a double-terminated 75

load. PSRR is defined as 20

log(ripple voltage at DAC output/ripple voltage at AVDD input). Limits from characterization only.
5.
Crosstalk spec applies to each possible pair of the 3 DAC outputs. Limits from characterization only.
6.
The imbalance between DACs applies to all possible pairs of the three DACs. KIMBAL is assured over full temperature range. In parts labeled
THS8134CPHP, KIMBAL(SYNC) is assured at 25
°
C. In parts labeled THS8134ACPHP, KIMBAL(SYNC) is assured over the full temperature range.

This bandwidth relates to the output amplitude variation in excess of the droop from the sinx/x sampled system. Since the output is a sample-and-hold
signal, a sin(

(

Fclk) roll-off is observed, which accounts e.g. at Fin = 40 MHz and Fclk = 80 MSPS for –3.92 dB signal drop (sync
droop). The total DAC output variation (device droop) consists of this and an additional amount (excess droop) caused by the output impedance of the
device, as shown in Table 5.
