1Hz to 10kHz Voltage to Frequency Converter

Jan 1st 1987
JFET inputs with anti phase-reversal circuitry allow the LTC1055/56 to be used as a precision, ultra-high impedance comparator. The precision provides for very high linearity of the V/F generation while the high speed allows a large frequency range of operation. ...

Fast, 16-Bit Current Comparator

Jan 1st 1987
Precision op-amp used as pre-comparator. Schottky diodes in feedback limit output swing of amplifier to minimize slew delay. Resistive input structure can be tailored for different trip points; this one detects a current sink of >50uA at the input ...
