ABSOLUTE MAXIMUM RATINGS
DC ELECTRICAL CHARACTERISTICS
(VCC = +3.3V ±10% or +5.0V ±10%, 100
load between OUT+ and OUT-, TA = -40°C to +85°C. Typical values are at VCC = +3.3V,
TA = +25°C, unless otherwise noted.)
AC ELECTRICAL CHARACTERISTICS
(VCC = +3.3V ±10% or +5.0V ±10%, 100
load between OUT+ and OUT-, source capacitance = 0.5pF, TA = -40°C to +85°C. Typical
values are at VCC = +3.3V, TA = +25°C, unless otherwise noted.) (Notes 1 and 2)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1: AC characteristics are guaranteed by design.
Note 2: Measured with a 3-pole filter at the output. CIN = 0.5pF, IIN = 0, CFILT = 1000pF.
Note 3: PSRR = -20log (
VOUT / VCC).
