= : 3 | LH0037/LH0037C Low Cost Instrumentation Amplifier a General Description Features The LH0037/LH0037C is a true instrumentation amplifier ™ High input impedance 300 M2 designed for precision differential signal processing. Ex- ™ High CMRR 10 dB tremely high accuracy can be obtained due to the 300 MN. Single resistor gain adjust 1 to 1000 input impedance and excellent 100 dB common-mode re- Low power 250 mw jection ratio. It is packaged in a hermetic TO-8 package im wide supply range +5V to +22V Gain is programmable with one external resistor from 110 Guard drive output 1000. Power supply operating range is between +5V and 222v. The LHO0037 is specified for operation over the —55°C to +125°C temperature range and the LHO037C is specified for operation over the —25°C to + 85°C temperature range.
