Note 1:
All devices are 100% production tested at T
A
= +25°C. All temperature limits are guaranteed by design.
Note 2:
Guaranteed by design.
Note 3:
The input common-mode range for IN_+ is guaranteed by a functional test. A similar test is done on the IN_- input. See the
Applications Information
section for more information on the input voltage range of the GainAmps.
Note 4:
For A
V
= -0.5V/V and A
V
= -0.25V/V, the output voltage swing may be limited by the input voltage range.
Note 5:
Includes noise from on-chip resistors.
Note 6:
The gain accuracy test is performed with the GainAmps in the noninverting configuration. The output voltage swing is limit-
ed by the input voltage range for certain gains and supply voltage conditions. For situations where the output voltage swing
is limited by the valid input range, the output limits are adjusted accordingly.
