| MITSUBISHI (Dig./Ana. INTERFACE) M62261FP VOLTAGE CONVERTER FOR MMIC DESCRIPTION The M62261FP is a C-MOS semiconductor circuit for driving MMIC, by connecting to the external capacitance, it can generate 2-times of inverting input voltage. With resident charge-pump type 2-times inverting input voltage circuit, -Vout and -2Vout can perform 2 kinds of negative source system. PIN CONFIGURATION (TOP VIEW) COSC 1 VIN 2 CP1 3 GND 4 8 -VOUT 7 -2VOUT 6 CP3 5 CP2 FEATURES *By connecting to external capacitance, it can generate 2-times of inverting input voltage.
