APPLICATIONS INFORMATION
Distortion
There are two main contributors to distortion in op amps:
output crossover distortion as the output transitions from
sourcing to sinking current and distortion caused by non-
linear common mode rejection. If the op amp is operating
in the inverting mode, there is no common mode induced
distortion. If the op amp is operating in the PNP input stage
(input is not within 1.3V of V+), the CMRR is very good,
typically 96dB. When the LT1797 switches between input
stages there is significant nonlinearity in the CMRR. Lower
load resistance increases the output crossover distortion,
but has no effect on the input stage transition distortion.
For lowest distortion the LT1797 should be operated single
supply, with the output always sourcing current and with
the input voltage swing between ground and (V+ – 1.3V).
See the Typical Performance Characteristic curves.
