模拟集成电路的低电压系统AnalogICsforLo

Abstract: This article about low-voltage ICs discusses many types of low-voltage ICs, including voltage regulators, data converters, op amps and current monitors, comparators, microprocessor supervisors, voltage references, analog switches, and interface transceivers. It also present information on power savings and how to manage issues related to low-voltage roductionLow voltages are most appropriate for use in systems where size, weight, and power consumption are especially critical such as PDAs, cell phones, and other battery-operated portable equipment. Low voltages also benefit line-powered systems because the lower power dissipation associated with lower voltage operation allows the use of smaller power supplies, heat-sinks, and w-voltage ICs are available in many of Maxim's product families including op amps, comparators, microprocessor supervisors, interface, data converters, analog switches and multiplexers, voltage references, DC-DC converters, digital potentiometers, and timing components such as real-time is discussion covers many of the analog IC families mentioned above, the power savings inherent in their operation, and how to handle some of the issues associated with low-voltage operation. It also presents methods for generating the lower voltages from a 5V supply. Table 1 presents a selection of Maxim's 1.8V, 2.5V, 3.0V, and 3.3V integrated ble 1.
