ADM660 Charge Pump Voltage Inverter Circuit Configuration and Datasheet

Description: The ADM660 is a charge-pump voltage converter that can either invert the input supply voltage or double it. The schematic below depicts the ADM660 Voltage Inverter Circuit Configuration Diagram. This inverting schematic is ideal for generating a negative rail in single power supply systems. To optimize capacitor size and quiescent current, there is a Frequency Control (FC) input pin instead of the external oscillator (OSC) pin, according to the datasheet. This device is commonly used in applications such as handheld instruments, portable computers, remote data acquisition, and operational amplifier power supplies. For complete information, refer to the ADM660 Datasheet.

The ADM660 is a versatile charge-pump voltage converter capable of performing both voltage inversion and doubling functions. It operates effectively in applications where a negative voltage rail is required, particularly in single-supply systems. The circuit configuration typically consists of a few essential components: the ADM660 IC itself, capacitors for charge storage, and external connections for input and output voltages.

The device's ability to invert or double the input voltage is facilitated by its internal charge pump circuitry, which utilizes capacitors to transfer charge efficiently. The inclusion of a Frequency Control (FC) input pin allows for fine-tuning of the operating frequency, which can enhance performance by optimizing the size of the capacitors used in the circuit while maintaining low quiescent current levels. This is particularly beneficial in battery-operated devices where power efficiency is critical.

The ADM660 is suitable for a wide range of applications, including portable electronics, where space and power constraints are paramount. It is also applicable in remote data acquisition systems, where stable and reliable power supplies are necessary. Furthermore, the device can be utilized to power operational amplifiers that require dual supply voltages.

In designing a circuit with the ADM660, it is essential to follow the recommended guidelines outlined in the datasheet. This includes selecting appropriate capacitor values to achieve the desired voltage conversion and ensuring that the input voltage levels are within the specified range for optimal performance.
