George Erdi Table 1 lists the parameters of importance. In all input
parameters (except noise) the advantage unquestionably goes to the choppers. 5ОјV maximum offset voltage, 0.5ОјV/В°C maximum drift are commonly found

3V Operation of Linear Technology Op Amps -Design Note 56
George Erdi
The latest trend in digital electronics is the introduction
of numerous ICs operating on regulated 3V or 3.3V
power supplies. This is a logical development to increase
circuit densities and to reduce power dissipation. In addition, many systems are directly powered by two AA
cells or 3V lithium batteries. Clearly, analog ICs which
work on 3V with good dynamic range to complement
these digital circuits are, and will be, in great demand.
Many Linear Technology operational ampliп¬Ѓers work
well on a 3V supply. The purpose of this design note
is to list these devices and their performance when
powered by 3V. The op amps can be divided into two
groups: single and dual supply devices. The single supply
op amps are optimized for, and fully speciп¬Ѓed at, a 5V
positive supply with the negative supply terminal tied
to ground. Input common mode voltage range goes
below ground, and the output swings to within a few
millivolts of ground while sinking current. Members of
the single supply family are the micropower LTВ®1077/
LT1078/LT1079 single, dual and quad op amps with
40ОјA supply current per ampliп¬Ѓer, the LT1178/LT1179 dual and quad with 13ОјA per ampliп¬Ѓer. The LT1006/
LT1013/LT1014 single, dual and quad have faster speed …
