`PROGRAMMABLE ELECTRICAL CHARAC-TERISTICS
`BATTERY POWERED OPERATION
`LOWSUPPLY CURRENT (250A/amplifier)
`GAIN-BANDWIDTH PRODUCT : 1MHz
`LARGEDC VOLTAGEGAIN : 120dB
`LOWNOISE VOLTAGE : 28nV/VHz
`WIDE POWER SUPPLY RANGE : ±1.5V to±22V
`CLASSE AB OUTPUT STAGE NO CROSSOVER DISTORTION
`OVERLOADPROTECTION FORINPUTS ANDOUTPUTS

Notes : 1. For supply voltages less than ±15V, the absolute maximum input vol tage is equal to the supply vol tage.
2. Any of the amplifier outputs can be shorted to ground indefinitly ; however more than one should not be
simultaneously shorted as the maximum junction temperature wil l be exceeded.

The LM246 consists of four independent, high gain, internally compensated, low power programmable amplifiers. Two external resistors (Rset) allow the user to program the gain-bandwith product, slew rate, supply current, input bias current, input offset current and input noise. For example the user can trade-off supply current for bandwidth or optimize noise figure for a given source resistance. In a similar way other amplifier characteristics can be tailored to the application.

Except for the two programming pins at the end of the package the LM346 pin out is the same as the LM246 and LM348.
