The LMP92066 is a highly integrated temperature-controlled dual DAC. Both DACs can be
programmed by two independent, user-defined, temperature-to-voltage transfer functions stored in
the internal EEPROM, allowing any temperature effects to be corrected without additional external
circuitry. Once powered up, the device operates autonomously, without intervention from the system
controller, to provide a complete solution for setting and compensating bias voltages and currents
in control applications.
The LMP92066 has two analog outputs that support two output ranges: zero to plus five
volts and zero to minus five volts. Each output can be switched to the load individually through
the use of the dedicated control pin. The output switching is designed for rapid response, making
the device suitable for the RF Power Amplifier biasing applications.
The EEPROM is verified for 100 write operations, enabling repeated field updates. The
EEPROM programming is completed upon the user-issued I2C command.
The LMP92066’s digital ports interface to a variety of system controllers, as the
dedicated VIO pin sets the digital I/O levels. The device is available in the thermally enhanced
PowerPAD™ package, enabling precise
PCB temperature measurement.
