o "(oo'I) J: ~National ~ Semiconductor .r.;.:I: o(o'I) LH0037/LH0037C Low Cost Instrumentation J: ...I Amplifier Amplifiers General Description The LH0037/LH0037C is a true instrumentation amplifier designed· for precision differential signal processing. Extremely high accuracy can be obtained due to the 300- Mn input impedance and excellent 100 dB common-mode rejection ratio. It is packaged in a hermetic TO-8 package. Gain is programmable with one external resistor from 1 to 1000. Power supply operating range is between ±5V and ±22V. The LH0037 is specified for operation over the -55°C to +125°C temperature range and the LH0037C is specified for operation over the -25°C to +85°C temperature range.
