Both DACs can be programmed – Accuracy (–40°C to 120°C), ±3.2°C by two independent, user-defined, temperature-to- (maximum) voltage transfer functions stored in the internal • Two Independent Transfer Functions Stored in EEPROM, allowing any temperature effects to be corrected without additional external circuitry. Once EEPROM powered up, the device operates autonomously, • Dual-Analog Output without intervention from the system controller, to – Two 12-Bit DACs provide a complete solution for setting and – Output Range 0 V to 5 V or 0 V to –5 V compensating bias voltages and currents in control applications. – High-Capacitive Load Tolerant, up to 10 µF The LMP92066 has two analog outputs that support – Post-Calibration Accuracy ±2.4 mV (typical) two output ranges: zero to plus five volts and zero to • Output On/Off Control Switching Time 50 ns minus five volts. Each output can be switched to the (typical) load individually through the use of the dedicated – Switching Time 50 ns (typical) control pin. The output switching is designed for rapid response, making the device suitable for the RF – RDSON 5 Ω (maximum) Power Amplifier biasing applications. • I2C Interface: Standard and Fast The EEPROM is verified for 100 write operations, – Nine Selectable Slave Addresses enabling repeated field updates. The EEPROM – TIMEOUT Function programming is completed upon the user-issued I2C • VDD Supply Range 4.75 V to 5.25 V command. • VIO Range 1.65 V to 3.6 V The LMP92066’s digital ports interface to a variety of • Specified Temperature Range –25°C to 120°C system controllers, as the dedicated VIO pin sets the digital I/O levels. The device is available in the • Operating Temperature Range –40°C to 125°C thermally enhanced PowerPAD™ package, enabling precise PCB temperature measurement. 2 Applications • GaN or LDMOS PA Bias Controller Device Information • Sensor Temperature Compensation PART NUMBER PACKAGE BODY SIZE • Timing Circuit Temperature Compensation LMP92066 HTSSOP (16) 5.00 mm x 4.40 mm 4 Simplified Schematic Residual Error After One Point Calibration 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
