Dual Buffered ±0.617V Reference Powered by Two AA Batteries

Nov 1st 1983
Lower opamp is a precision inverter setting outputs to set the outputs at the same magnitude but opposite polarity. The upper opamp drives the positive output so that the difference of the two outputs is the reference voltage, so the result is that half the reference voltage is the magnitude of the outputs. ...

Linear Thermometer

Nov 1st 1983
T1 has a built in pair of thermistors with linearizing resistors custom scaled for a specific temperature range., 0C to 100C in this example. The flying capacitor LTC1043 eliminates any dc loading on the precision network to maintain linearity over the entire temperature range. Amplifier gain is scaled to provide an output of ...

LT1028/LT1055/LT1004 Super Low Distortion Variable Sine Wave Oscillator

Nov 1st 1983
The LT1028(gain of –1 stable)/LT1128(gain of +1 stable) achieve a new standard of excellence in noise performance with 0.85nV/rtHz 1kHz noise, 1.0nV/rtHz 10Hz noise. This ultralow noise is combined with excellent high speed specifications (gain-bandwidth product is 75MHz for LT1028, 20MHz for LT1128), distortion-free output, ...
