Op amps combine low cost and high precision
The LT1112 dual and LT1114 quad op amps have a typical offset voltage of
20 microvolts and a maximum offset voltage of 75 microvolts for the
low-cost grades. In addition, the offset voltage drift is a guaranteed
maximum of 0.5 microvolts/ degreesC (0.75 microvolts/ degreesC for the
low-cost grades.) Other features of the LT1112/4 include power
consumption of 400 microamps, 0.1 to 10-Hz noise of 0.32 microvoltsp-p,
and a slew rate of 0.3 V/μs. The minimum open-loop gain into a 10-kohm
load is 1 million V/V (5 million typ). The LT1112 is available in 8-lead
DIPs and SO packages; the LT1114 comes in 14-lead plastic and ceramic
DIPs. (From $2.45 ea/100–available now.) Linear Technology Corp.
