Texas Instruments' 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: 0 to +5 V and 0 to -5 V. Each output can be switched to the load individually through the use of the dedicated control terminal. The output switching is designed for rapid response, making the device suitable for the RF power amplifier biasing applications.
