Embarking as the smallest available, the MAX14515 dc-to-ac liquid lens driver targets tiny autofocus camera modules with a footprint of 2 mm x 1 mm in a WLP. It delivers a high-voltage differential output through an I2C interface and employs a charge-pump topology to reduce the number of external components. The MAX14515 requires, at most, two small external capacitors: one low-voltage capacitor and a tiny bypass capacitor. The device integrates an eight-bit monotonic DAC with a single differential, high-voltage output to set the amplitude. It delivers up to 42 Vrms into a 200 pF liquid lens load at 1.1 kHz and operates over a temperature range from -40?C to +85?C. Price is $1.50 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA.
