G1626 Global Mixed-mode Technology 7-bit Programmable VCOM Calibrator with Write Protected Integrated Nonvolatile Memory Features General Description Integrated Nonvolatile Memory to Store 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. Sink-Current Setting 100 Programming Times Write Protection Function I 2C Interface 7-Bit, Adjustable Sink-Current Device Resistor-Adjustable, Full-Scale Range 2.5V to 3.6V Logic Supply Range 7V to 18V Analog Supply Range Protections: Over Temperature Protection (OTP) TDFN3X3-8 Package RoHS Compliant G1626 includes one time programmable (OTP) memory 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.
