LM146/LM346
Programmable Quad Operational Amplifiers
General Description
The LM146 series of quad op amps consists of four independent,
high gain, internally compensated, low power, programmable
amplifiers. Two external resistors (RSET) allow
the user to program the gain bandwidth 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 LM146
pin-out is the same as the LM124 and LM148.
