LM246
DESCRIPTION te The LM346 consists of four independent, high gain, internally pensated, low power program- le mable amplifiers. Two external resistors (Rset) alo low the user to program the gain-bandwith prodbs uct, slew rate, supply current, input bias current, input offset current and input noise. For example
O the user can trade-off supply current for bandwith
- or optimize noise figure for a given source resist(s) tance. In a similar way other amplifier characteris- tics can be tailored to the application. c Except for the two programming pins at the end of u the package the LM346 pin out is the same as the rod LM324 and LM348. P PROGRAMMING EQUATIONS : te Total supply current = 1m A (Iset = 10µA) le Gain bandwith product = 1MHz (Iset = 10µA) o Slew rate = 0.5V/µs (Iset = 10µΑ) s Input bias current ≈30n A (Iset = 10µΑ) Ob Iset = current into pin 8 and pin 9 (see schematic
