General Description
The G1626 provides a programmable sink-current
output that attaches to an external voltage divider. The
increase in output sink current lowers the voltage on
the external divider, which is applied to an external
VCOM buffer amplifier.
G1626 includes one time programmable (OTP) mem-
ory to store the DAC code on the chip, eliminating the
need for external EEPROM. The chip supports up to
100 write operations to OTP memory. G1626 has an
I2C interface to set the sink current setting and write
into OTP memory.
