Introduction

Linear Technology’s next generation LT1167 instrumentation amplifier uses a single resistor to set gains from 1 to 10,000. The single gain-set resistor eliminates expensive resistor arrays and improves VOS and CMRR performance. Careful attention to circuit design and layout, combined with laser trimming, greatly enhances the CMRR, PSRR, gain error and nonlinearity, maximizing application versatility. The CMRR is guaranteed to be greater than ...
