The CLM7660 is a DC-to-DC voltage converter from Calogic that can generate a negative voltage from a positive source. The input voltage range is 1.5V to 10V and the output voltage range is -1.5V to -10V. The device is used in various analog/digital converters, operational amplifiers and multiplexers.
The Calogic CLM7660 is an integrated circuit designed to generate a negative voltage from a positive source. It converts +5V logic supply levels to -5V system levels, allowing digital systems to incorporate analog components like operational amplifiers without additional power sources. The device operates with a wide input voltage range of 1.5V to 10V and features low power consumption.
| Supply Voltage Range, High (0°C < Ta <+70°C) | 3 - 6.5 V |
|---|---|
| Supply Current | 80 mA (Typical) |
| Power Efficiency | 95% to 98% |
| Voltage Conversion Efficiency | 97% to 99.9% |
| Oscillator Frequency | 10 kHz (Typical) |
Applications include A-to-D converters, D-to-A converters, multiplexers, and operational amplifiers.
The operating temperature range is -40°C to +85°C.
Users must never exceed maximum supply voltages, never connect LV terminal to GND for supply voltages over 3.5V, and avoid short circuiting the output.
