The LTC1550CGN from Analog Devices is a precision inverting charge pump DC-DC converter. It operates from a 4.5V to 6.5V input and generates a regulated negative output voltage from -1.24V to -6.1V. With a maximum output current of 10mA and a 900kHz switching frequency, it provides a compact and efficient solution for generating negative supply rails. This device is ideal for biasing op-amps, LCD displays, and other analog circuits that require a negative voltage in single-supply systems.
- Negative Voltage Generation: Easily creates a negative rail from a positive input without the need for a transformer or inductor.
- Compact and Simple: Requires only a few external capacitors, saving board space and simplifying design.
- Low Noise Operation: The 900kHz switching frequency allows for small filtering components, reducing output ripple.
- Precise Regulation: Provides a stable, adjustable negative output for sensitive analog applications.
Negative Rail Generation for Op-Amps
Provides a clean, regulated negative supply voltage for operational amplifiers and other analog circuits in single-supply systems, enabling true bipolar operation.
Biasing for LCD Displays
Can generate the negative bias voltage required for certain LCD display panels, simplifying the power supply design in portable instruments.
Sensor and DAC/ADC Supplies
Supplies a stable negative rail for high-precision sensors, digital-to-analog converters (DACs), and analog-to-digital converters (ADCs) that require a bipolar supply.
GaAs FET Biasing
Used in RF applications to provide a negative gate bias voltage for Gallium Arsenide (GaAs) field-effect transistors (FETs).
Audio Equipment
Creates a negative supply rail for audio amplifiers and signal processing circuits, improving dynamic range and reducing distortion.
