## Exponential Voltage-to-Frequency Converter for Music Synthesizers

Jan 1st 1987

Logarithmic characteristic of BJT is used to provide an exponential control effect on V/F function. By using a multiple transistor array, a thermal stabilization circuit assures a constant operating point for the log function. ...

## LT1055 ±120V Output Precision Op Amp

Jan 1st 1987

Simple shunt regulators provide normal supply levels to the op amp and the external open-loop gain and buffer structure extends the output swing to nearly the high-voltage rails. Output transistors are protected by current-limiting. ...

## Temperature-to-Frequency Converter

Jan 1st 1987

Precision oscillator structure uses SCR effect to discharge integration capacitor. A temperature dependent device (LM134) effects the integrator trip point to form a variable interval. An output transistor detects the reset action and forms a logic pulse. ...

## 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, ...
