As V approaches V+ CM devices in the cancellation circuitry saturate causing I to The positive supply of the LT6003/LT6004/LT6005 should B increase (in the nanoamp range). Input offset voltage errors be bypassed with a small capacitor (about 0.01μF) within due to I can be minimized by equalizing the noninverting an inch of the pin. When driving heavy loads, an additional B and inverting source impedances. 4.7μF electrolytic capacitor should be used. When using split supplies, the same is true for the negative supply pin. The input offset voltage changes depending on which input stage is active; input offset voltage is trimmed on Rail-to-Rail Characteristics both input stages, and is guaranteed to be 500μV max in the PNP stage. By trimming the input offset voltage of The LT6003/LT6004/LT6005 are fully functional for an input both input stages, the input offset voltage shift over the signal range from the negative supply to the positive sup- entire common mode range (CMRR) is typically 160μV, ply.

Capacitor C1 reduces the unity swing within 100mV of the positive rail and 50mV of the cross frequency and improves the frequency stability negative rail with no load, over the industrial temperature without degrading the gain bandwidth of the amplifier. range. The LT6003/LT6004/LT6005 can typically source The complementary drive generator supplies current to 8mA on a single 5V supply. Sourcing current is reduced the output transistors that swing from rail to rail. to 5mA on a single 1.8V supply as noted in the electrical characteristics.

As VCM approaches V– the cancellation circuitry turns output to V– will cause unlimited currents to flow when off and IB is determined by the tail current of Q2 and the the output is forced below V–.

Another circuit creates a negative offset When a positive signal step is applied to the input, the forcing the output to come up saturated low, while the last output of A3 rises. When a negative signal step is applied circuit brings the output up at 1/2 supply. In all cases, the to the input, the output of A4 rises.
