■
Input offset voltage is trimmed to less than 35µV. The low
drift and excellent long-term stability guarantee a high
accuracy over temperature and over time. The 110pA
maximum input bias current and 120dB minimum voltage
gain further maintain this precision over operating
conditions.

TheLT6010worksonanypowersupplyvoltagefrom2.7V
to 36V, and draws only 135µA of supply current on a 5V
supply. A power saving shutdown feature reduces supply
current to 12µA. The output voltage swings to within
40mV of either supply rail, making the amplifier a good
choice for low voltage single supply operation.
