The INA143 can be combined with op amps to form a complete instrumenta-
tion amplifier with specialized performance characteristics. Burr-Brown offers
many complete high performance IAs. Products with related performances
are shown at the right in the table below.
FIGURE 9. Precision G = 11 Buffer.
FIGURE 4. Difference Amplifier with Gain and CMR Adjust.
FIGURE 5. Precision G = –10 Inverting Amplifier.
This circuit follows an 11/1 divider with a gain of 11 for an overall gain of unity.
With an 11/1 divider, the input signal can exceed 55V without damage as
long as input current is less than 0.5mA.
