The LB2032B/S/Z is a highly integrated, low-power analog monitoring solution that includes thirty-two 12-bit digital-to-analog converters (DACs), six or five flexible pins that can be configured as inputs to a 12-bit analog-to-digital converter (ADC) or as general-purpose input/output (GPIO), internal reference, and local temperature sensor channel. The high level of integration simplifies closed-loop system design, making it an ideal choice for multi-channel applications where board space, size, and low power consumption are critical.The device's low power consumption, extremely high integration, and wide operating temperature range make it suitable for use as a low-cost, integrated bias control circuit for power amplifiers (PAs) in multi-channel radio frequency (RF) communication systems. The flexible DAC output range allows the device to be used as a bias solution for various transistor technologies, such as LDMOS, GaAs, and GaN. The feature set of the LB2032B/S/Z is equally applicable to general-purpose monitoring systems.
