ISL24202
ISL24202 is Programmable Vcom Calibrator manufactured by Renesas.
Programmable V Calibrator with EEPROM
The ISL24202 is an 8-bit programmable current sink that can be used in conjunction with an external voltage divider to generate a voltage source (V) positioned between the analog supply voltage and ground. The current sink’s full-scale range is controlled by an external resistor, RSET. With the appropriate choice of external resistors R1 and R2, the V voltage range can be controlled between any arbitrary voltage range. The ISL24202 has an 8-bit data register and 8-bit EEPROM for storing both a volatile and a permanent value for its output, accessible through a single up/down counter interface pin (CTL). After the part is programmed with the desired V value, the Counter Enable pin (CE) can be grounded to prevent further changes. On every power-up the EEPROM contents are automatically transferred to the data register, and the pre-programmed output voltage appears at the VOUT pin.
The ISL24202 can be used with a high output...
