Note 1:
These errors are in the order of the conversion noise shown in Tables 1 and 3. This applies after calibration at the given
temperature.
Recalibration at any temperature removes these drift errors.
Positive full-scale error includes zero-scale errors (unipolar offset error or bipolar zero error) and applies to both unipolar
and bipolar input ranges.
Full-scale drift includes zero-scale drift (unipolar offset drift or bipolar zero drift) and applies to both unipolar and bipolar
input ranges.
Gain error does not include zero-scale errors. It is calculated as (full-scale error – unipolar offset error) for unipolar ranges,
and (full-scale error – bipolar zero error) for bipolar ranges.
Gain-error drift does not include unipolar offset drift or bipolar zero drift. Effectively, it is the drift of the part if only zero-
scale calibrations are performed.
The analog input voltage range on AIN+ is given here with respect to the voltage on AIN- on the MAX1415/MAX1416.
This common-mode voltage range is allowed, provided that the input voltage on the analog inputs does not go more posi-
tive than (V
DD
+ 30mV) or more negative than (GND - 30mV). Parts are functional with voltages down to (GND - 200mV),
but with increased leakage at high temperature.
Note 9:
The REF differential voltage, V
REF
, is the voltage on REF+ referenced to REF- (V
REF
= V
REF+
- V
REF-)
.
Note 10:
Guaranteed by design.
Note 11:
These calibration and span limits apply, provided that the absolute voltage on the analog inputs does not exceed (V
DD
+
30mV) or go more negative than (GND - 30mV). The offset-calibration limit applies to both the unipolar zero point and the
bipolar zero point.
Note 12:
When using a crystal or ceramic resonator across the CLKIN and CLKOUT as the clock source for the device, the supply
current and power dissipation varies depending on the crystal or resonator type. Supply current is measured with the digi-
tal inputs connected to 0 or V
DD
, CLKIN connected to an external clock source, and CLKDIS = 1.
Note 13:
If the external master clock continues to run in power-down mode, the power-down current typically increases to 67μA at
3V. When using a crystal or ceramic resonator across the CLKIN and CLKOUT as the clock source for the device, the
clock generator continues to run in power-down mode and the power dissipation depends on the crystal or resonator type
(see the
Power-Down Modes
section).
Note 14:
Measured at DC and applied in the selected passband. PSRR at 50Hz exceeds 120dB with filter notches of 25Hz or 50Hz.
PSRR at 60Hz exceeds 120dB with filter notches of 20Hz or 60Hz.

Note 3:
Note 4:
Note 5:
Note 6:
Note 7:
Note 8:
PSRR depends on both gain and V
DD
.
Note 15:
Provide f
CLKIN
whenever the MAX1415/MAX1416 are not in power-down mode. If no clock is present, the device can draw
higher-than-specified current and can possibly become uncalibrated.
Note 16:
All input signals are specified with t
r
= t
f
= 5ns (10% to 90% of V
DD
) and timed from a voltage level of 1.6V.
