The MAX2045/MAX2046/MAX2047 provide vector adjustment through the differential I/Q amplifiers. The I/Q amplifiers can interface with voltage and/or current digital-to-analog converters (DACs). The voltage inputs are designed to interface to a voltage-mode DAC, while the current inputs are designed to interface to a currentmode DAC. An internal 2.5V reference voltage is provided for applications using single-ended voltage DACs. The MAX2045/MAX2046/MAX2047 operate from a 4.75V to 5.25V single supply. All devices are offered in a compact 5mm 5mm, 32-lead thin QFN exposed-paddle packages.
