TYPICAL APPLICATIONS

FIGURE 3. Precision Instrumentation Amplifier.

The INA152 can be combined with op amps to form a complete Instrumen-

tation Amplifier (IA) with specialized performance characteristics. Texas

Instruments offers many complete high performance IAs. Products with

related performances are shown at the right in the table below.

Ω (1% max mismatch) to maintain excellent CMR.

With 100

Ω resistors, gain error is increased to 0.5%.
