APPLICATIONS INFORMATION
OFFSET VOLTAGE ADJUSTMENT
The OPA606 offset voltage is laser-trimmed and will require
no further trim for most applications. As with most amplifi-
ers, externally trimming the remaining offset can change
drift performance by about 0.5µV/°C for each millivolt of
adjusted offset. Note that the trim (Figure 1) is similar to
operational amplifiers such as LF156 and OP-16. The
OPA606 can replace most other amplifiers by leaving the
external null circuit unconnected.
