LTC1340 - Low Noise/ Voltage-Boosted Varactor Driver

General Description

The LTC®1340 is a varactor diode driver designed to generate 5V varactor drive from a single 3V or higher voltage supply.

It includes a low noise amplifier with an internal gain of 2.3 and a self-contained charge pump to generate output voltages above the input supply.

LTC1340 Low Noise, Voltage-Boosted Varactor Driver FEATURES s s s s s s s s s s s DESCRIPTION The LTC®1340 is a varactor diode driver designed to generate 5V varactor drive from a single 3V or higher voltage supply. It includes a low noise amplifier with an internal gain of 2.3 and a self-contained charge pump to generate output voltages above the input supply. The amplifier input stage includes a built-in offset voltage that allows the output voltage to swing to ground without requiring OV on the input. This feature maintains the phase detector within its linear range of operation. The LTC1340 requires only three external surface mount capacitors to implement a complete varactor driver module.
