MAX865EUA+T

The MAX865EUA+T is a compact, dual-output charge pump in 8 pin µMAX package. It produces positive and negative outputs from a single positive input and requires only four capacitors. The charge pump first doubles the input voltage and then inverts the doubled voltage. The input voltage ranges from +1.5V to +6V. The internal oscillator is guaranteed to be between 20KHz and 38KHz, keeping noise above the audio range while consuming minimal supply current. 75ohm output impedance permits useful output currents up to 20mA. The MAX865 comes in a 1.11mm-high, 8-pin μMAX package that occupies half the board area of a standard 8-pin SOIC. Typical applications include low voltage GaAsFET bias in wireless handsets, VCO and GaAsFET supplies, split supply from 3 Ni cells or 1 Li+ cell, low-cost split supply for low voltage, data-acquisition systems, split supply for analogue circuitry and LCD panels.
