Low Noise AC Amplifier with Programmable Gain and Bandwidth

Jan 20th 2000
Two LTC6910 programmable gain amplifiers can be combined to provide independent gain and bandwidth control using two 3 bit digital words. The Gain Control PGA simply varies the circuit gain from 1 to 100. The Bandwidth Control PGA puts signal gain inside the feedback loop of the amplifier. As this gain is increased the effective ...

5V Powered, Quartz-Stabilized 10kHz Voltage to Frequency Converter has 0.0015% Linearity and 8ppm/°C Temperature Coefficient

Nov 16th 1992
Almost all precision voltage-to-frequency converters utilize charge pump based feedback for stability. These schemes rely on a capacitor for stability. A great deal of effort towards this approach has resulted in high performance V to F converters. Obtaining temperature coefficients below 100ppm/°C requires careful attention ...
