Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Guaranteed by design and characterization. This parameter is not
tested.
AC ELECTRICAL CHARACTERISTICS
The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T
A
= 25°C (Note 3). V
CC
= 5V, Z
SOURCE
= Z
LOAD
= 50Ω unless otherwise noted.
Measurements are performed using Test Circuit A, measuring from 50Ω SMA to 50Ω without de-embedding (Note 4).

Note 3: The LTC6431-20 is guaranteed functional over the case operating
temperature range of –40°C to 85°C.
Note 4: Small-signal parameters S and noise are de-embedded to the
package pins, while large-signal parameters are measured directly from
the circuit.
