LT1495
A new dual op amp with only 1μA power consumption and precision DC specifications permits high performance portable applications. The LT1495 has 375μV offset, 2μV/°C drift, 1 nA bias current and 100dB of open-loop gain. These attributes, combined with careful design, make portable, high performance circuitry possible.
5.5μA, 0.05μV/°C chopped amplifier
Figure 435.1 shows a chopped amplifier requiring only 5.5μA supply current. Offset ...
