General Description
The PDA50 is designed to drive capacitive loads
such as the TLens® autofocus actuators. It has a
10-bit DAC and is capable of 50V output voltage.
The PDA50 uses an I2C interface operating at up
to 400KHz. The power-on reset circuit guarantees
0V output voltage at start-up. It has a powerdown feature that reduces current consumption
in standby to below 5uA.
