SNOSBT4C – MAY 1999 – REVISED MARCH 2013

The DC input voltage at each input is a transistor VBE(≃ 0.6 VDC) and must be considered for DC biasing. For

most applications, the supply voltage, V+, is suitable and convenient for establishing IIN(+). The inverting input

bias current, Ib(−), is a direct function of the programmable input stage current (see OPERATING CURRENT

PROGRAMMABILITY (ISET)) and to obtain predictable output DC biasing set IIN(+) ≥ 10Ib(−).

The following figures illustrate typical biasing schemes for AC amplifiers using the LM359:
