Capacitorless Active Filters (Basic Circuit)
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

ESD rating is to be determined.
(1) Refer to RETS146X for LM146J military specifications.
(2) For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage.
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(4) The maximum power dissipation for these devices must be derated at elevated temperatures and is dictated by T
jMAX
, θ
jA
, and the
ambient temperature, T
A
. The maximum available power dissipation at any temperature is P

,
whichever is less.
(5) Any of the amplifier outputs can be shorted to ground indefinitely; however, more than one should not be simultaneously shorted as the
maximum junction temperature will be exceeded.
