Electrical characteristics—ADC specifications (con’t)
Table 28 (SDn ADC electrical specification):
• Removed the I
LK_IN
specification from table.
•For SNR
DIFF150
, SNR
DIFF333
, and SNR
SE150
specifications, added reference to “S/D
ADC is functional in the range 3.0 V < VDD_HV_ADR_D , 4.0 V. . .” footnote.
•Moved V
REF_BG_T
, V
REF_BG_TC
and V
REF_BG_LR
specifications from ADC pin
specification table to Device operating table.
• Removed I
BG
specification as it is already provided in the DC electrical table.
• Maximum value of parameter “GAIN” changed from “16” to “15”
Table 28 (SDn ADC electrical specification):
• Changed footnote from “The ±1% passband ripple specification is equivalent to 20 *
log
10
(0.99) = 0.87 dB.” to “The ±1% passband ripple specification is equivalent to 20
* log
10
(0.99) = 0.087 dB.”
• Max value of 
GROUP
modified for all values of OSR.
•t
LATENCY,
t
SETTLING
and t
ODRECOVERY:
“HPF = ON” and “HPF = OFF” conditions added.
New max values.
• Added SINAD and THD specifications.
• RESOLUTION specification, added footnote “When using a GAIN setting of 16, the
conversion result will always have a value of zero in the least significant bit. The gives
an effective resolution of 15 bits.”
• 
GAIN
specification, changed Max value from ”1” % to “1.5” %, “0.1” % to “5” mV, “0.25”
% to “7.5” mV, and “0.5 %” to 10” mV”.
•VOFFSETspecification, added 3 “After calibration” conditions, 
VDD_HV_ADR_D
< 5%

VDD_HV_ADV_D
< 10% T
J
< 50 °C, Max value of “5” mV, 
VDD_HV_ADR_D
< 5%

VDD_HV_ADV_D
< 10% T
J
< 100 °C, Max value of “7.5” mV and “After calibration”
conditions, 
VDD_HV_ADR_D
< 5% 
VDD_HV_ADV_D
< 10% T
J
< 150 °C, Max value of
“10” mV.
• Changed all SNR specification “Unit”s from “dB” to “dBFS”.
• Changed SFDR specification “Unit” from “dB” to “dBc”.
•Z
IN
specification, changed footnote to “Input impedance is valid over the full input
frequency range.Input impedance is calculated in megaohms by the formula
25.6/(Gain * f
ADCD_M
).
• Common mode rejection ratio parameter changed symbol from “—” to “V
cmrr
”.
• Anti-aliasing filter parameter, changed symbol “—” to “R
Caaf
”.
• Stop band attenuation parameter, changed symbol “—” to “F
rolloff
”.
• Changed footnote in 13 “full input range (specified by Vin)” to “full input frequency
range.”
• Changed in footnote 15 “0.873” dB to “0.087” dB.
•f
ADCD_M
, changed “S/D clock 3(4)” to “S/D Modulator Input Clock” and replaced “—”
with “4” in Min column.
•f
ADCD_S
changed “conversion rate'” to “output conversion rate”.
