The ADM8660AR from Analog Devices is a CMOS switched-capacitor voltage converter that inverts the input supply voltage. It operates with input voltages ranging from +1.5 V to +7 V, providing a negative output supply of -1.5 V to -7 V. This inverting capability is ideal for generating a negative rail in single power supply systems.
Key features include an output current capability of up to 100 mA and a low quiescent current of 600 µA. The charge pump frequency is selectable between 25 kHz and 120 kHz, allowing optimization of external capacitor size and quiescent current. A voltage drop of only 0.3 V at a 30 mA load is achievable. The ADM8660AR is available in a compact 8-SOIC package suitable for surface mounting.
This device is pin-compatible with older parts like the MAX660 and ICL7660, offering an upgrade path for existing designs. Applications include handheld instruments, portable computers, remote data acquisition, and op amp power supplies where a negative voltage rail is required from a positive supply.
