The MAX44298 is a low-side current, voltage, and power monitoring circuit that provides an analog output current proportional to the measured current, voltage, and the internally calculated instantaneous power.Instantaneous power is calculated internally by multiplying the load current and a fraction of the load voltage set by an external resistive divider. All three outputs are scaled to a full-scale current of either 100µA or 50µA. This full-scale current option is set with a simple pin-strap, ISET. An additional output current of either 100µA or 50µA is available at the reference (REF) output; this current can be used to create a reference voltage for the ADC that is being used to measure the power, voltage, and current signals.By providing the ADC with both the measured signals and the input reference voltage, the ADC can make a ratio- metric measurement, allowing improved accuracy. The use of currents, rather than voltage, to convey the mea- sured signals to the ADC eliminates any errors caused by voltage drops across the parasitic resistance of PCB, which can be significant for high-current systems. To allow full-system calibration, the CAL bump provides a way to calibrate gain and offset for the ADC.The MAX44298 measures load current by using a precision, auto-zeroed current-sense amplifier (CSA), which due to its ultra-low offset voltage allows precise measurement of full-scale voltages of 5mV, 10mV, and 20mV. The load voltage is measured via a user-selectable resistive network, dividing the input voltage down to a full scale of 1.00V.The wide supply voltage range of 3V to 5.5V allows the simple sharing of supplies with either the ADC or a micro-controller. The MAX44298 can be powered down and the outputs will then go high impedance. The device is available in a 2.4mm x 2.4mm, 16-bump WLP package and is specified for the 0°C to +85°C temperature range.ApplicationsPower Monitoring and Management Data Center and TelecomRenewable Energy SystemSmart Battery Packs and Chargers

The MAX5717 and MAX5719 are serial-input, unbuffered 16 and 20-bit voltage-output unipolar digital-to-analog converters (DACs) with integrated feedback resistors that allow bipolar operation when used with an external operational amplifier. These DACs provide low glitch energy, low noise, tight bipolar resistor matching, and high accuracy. The DACs feature 1LSB INL (max, MAX5717A)over the temperature range of -40°C to +105°C. Integrated precision setting resistors make the DACs easy to use. The MAX5717 and MAX5719 feature a 50MHz, 3-wire SPI™, QSPI™, MICROWIRE™, and DSP-compatible serial interface.On power-up, the output resets to zero-scale, providing additional safety for applications which drive valves or other transducers that need to be off on power-up. The DAC output settles in 750ns and has a low offset and gain drift of ±0.1 ppm/°C of FSR. The MAX5717 is functionally similar to the MAX542, but with significantly faster settling time. The MAX5719 provides a similar speed improvement as well as an increase in resolution to 20 bits.ApplicationsAutomatic Test EquipmentAutomatic TuningCommunication SystemsData-Acquisition SystemsGain and Offset AdjustmentPortable InstrumentationProcess Control and Servo LoopsProgrammable Voltage and Current SourcesTest and Measurement Equipment

The MAX77756 is a synchronous 500mA step-down DC-DC converter with integrated dual-input power multiplexer (MUX). The converter operates on an input supply as low as 3.0V and as high as 24V. Default output voltage is factory-programmed to either 1.8V, 3.3V, or 5.0V. Output voltage is further adjustable through external resistors or an I2C serial interface. The dual-input power MUX selects the higher voltage from two different input sources to power the step-down converter. Control circuitry ensures that only one channel of the MUX is on at a time to prevent cross-conduction between input sources. For single-input applications, the MUX can be bypassed and the step-down converter can be powered directly from the SUP pin.
