The LTC1261IS8 is an 8-pin integrated circuit designed for use as a switched-capacitor voltage inverter. It is primarily used to generate a negative supply voltage from a positive input voltage. The pin configuration and functions are as follows:
1. V+ (Pin 1): Positive supply voltage input.
2. C1+ (Pin 2): Positive terminal for the charge pump capacitor.
3. C1- (Pin 3): Negative terminal for the charge pump capacitor.
4. GND (Pin 4): Ground connection.
5. OUT (Pin 5): Output pin, provides the inverted voltage.
6. SHDN (Pin 6): Shutdown pin, active low, used to enable or disable the device.
7. FC (Pin 7): Frequency control pin, adjusts the oscillator frequency.
8. V- (Pin 8): Negative supply voltage output.
The device operates by using an internal oscillator to switch the charge pump capacitors, effectively inverting the input voltage to produce a negative output. This makes it suitable for applications requiring a negative voltage rail.
