High-Voltage Liquid Lens Driver  
MAX415  
General Description  
Features  
o Small Footprint for Placement Inside Camera  
Modules  
The MAX14515 high-voltage liquid lens driver features a  
2
high-voltage differential output controlled through an I C  
interface. The MAX14515 uses a charge-pump-based  
boost converter and integrated H-bridge to provide a  
compact lens driver solution with minimal external com-  
ponents to achieve a small overall footprint suitable for  
small space constraints inside camera modules.

o 8-Bit Output Voltage Resolution  
o Guaranteed Monotonic Output  
The MAX14515 features an 8-bit monotonic DAC with a  
single differential high-voltage output controlled by a  
2-wire I C interface to set the amplitude. The high-volt-

age outputs are capable of delivering up to 42V  
(min) into a 220pF liquid lens load at 1.0kHz (min).  
RMS  
o Low 500nA (max) Shutdown Current  
o +2.7V to +5.5V Input Voltage Range  
o Space-Saving, 8-Bump WLP (1mm x 2mm) Package  
The MAX14515 also features two power-saving modes  
(shutdown mode and sleep mode) to minimize power  
consumption when the device is inactive. Shutdown  
mode places the device in a low-power state that resets  
2
all registers and disables the I C interface to reduce cur-  
rent below 500nA (max). In sleep mode, the power-on  
reset circuit remains active. If no activity is detected on  
2
the I C interface, current consumption is less than 3µA.  
The MAX14515 operates over the +2.7V to +5.5V sup-  
ply voltage range, ideal for portable applications using  
lithium ion battery sources. The MAX14515 is specified  
over the -40°C to +85°C extended temperature range  
and is available in a small (1mm x 2mm) 8-bump WLP  
package.
