Description

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.
