(1)
PSRR is measured with a 0.1-mF capacitor between the COMP and AVDD pins and with a 0.1-mF capacitor connected between the VREF
and AVSS pins. 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
(= 37.5 ) load. PSRR is defined as 20 × log(ripple voltage at DAC output/ripple voltage at AVDD input). Limits
are from characterization only.
(2)
The imbalance between DACs applies to all possible pairs of the three DACs.
(3)
Values at RFS = RFS(nom)
(4)
From characterization only. Measured on the AG channel with RFS = RFS(nom).
(5)
This value excludes the digital process delay, tD(D). Limit are from characterization only.
