This device is ideal for systems requiring isolated ground returns or large common mode voltage variations. Uninterrupted communication is guaranteed for common mode transients greater than 50kV/μs.Enhanced ESD protection allows this part to withstand up to ±20kV (human body model) on the USB transceiver interface pins to local supplies and ±20kV through the isolation barrier to supplies without latch-up or damage.Applications Isolated USB Interfaces Host, Hub, or Device Isolation Industrial/Medical Data Acquisition

The MAX11301 integrates a PIXI™, 12-bit, multichannel, analog-to-digital converter (ADC) and a 12-bit, multichannel, buffered digital-to-analog converter (DAC) in a single integrated circuit. This device offers 20 mixed-signal high-voltage, bipolar ports, which are configurable as an ADC analog input, a DAC analog output, a general-purpose input (GPI), a general-purpose output (GPO), or an analog switch terminal. One internal and two external temperature sensors track junction and environmental temperature. Adjacent pairs of ports are configurable as a logic-level translator for open-drain devices or an analog switch.Custom designs are easily created using the MAX11301 configuration GUI software. Watch this video to learn (Mandarin) how to create a design using the MAX11300 GUI configuration software and the MAX11301 Evaluation Kit.PIXI ports provide highly flexible hardware configuration for 12-bit mixed-signal applications. The MAX11301 is best suited for applications that demand a mixture of analog and digital functions. Each port is individually configurable with up to four selectable voltage ranges within -10V to +10V.The MAX11301 allows for the averaging of 2, 4, 8, 16, 32, 64, or 128 ADC samples from each ADC-configured port to improve noise performance. A DAC-configured output port can drive up to 25mA. The GPIO ports can be programmed to user-defined logic levels, and a GPI coupled with a GPO forms a logic-level translator.Internal and external temperature measurements monitor programmable conditions of minimum and maximum temperature limits, using the interrupt to notify the host if one or more conditions occur. The temperature measurement results are made available through the serial interface.The MAX11301 features an internal, low-noise 2.5V voltage reference and provides the option to use external voltage references with separate inputs for the DAC and ADC. The MAX11301 uses a 400kHz I²C-compatible serial interface, operating from a 5V analog supply and a 1.8V to 5.0V digital supply. The PIXI port supply voltages operate from a wide -12.0V to +12.0V.The MAX11301 is available in a 40-pin TQFN, 6mm x 6mm package or a 48-pin TQFP, 9mm x 9mm package specified over the -40°C to +105°C temperature range.ApplicationsBase-Station RF Power Device Bias ControllersControl for Optical ComponentsIndustrial Control and AutomationPower-Supply MonitoringSystem Supervision and Control

The MAX12900 is an ultra-low-power, highly integrated 4-20mA sensor transmitter. The MAX12900 integrates ten building blocks in a small package: a wide input supply voltage LDO, two conditioner circuits for pulse-width modulated (PWM) inputs, two low-power, low-drift, general purpose operational amplifiers (op amp) one wide bandwidth, zero-offset drift operational amplifier; two diagnostic comparators, a power-up sequencer with power good output to allow for a smooth power-up, and a low-drift voltage reference.The MAX12900 converts PWM data from a microcontroller into current over a 4-20mA loop with two, three, or four wire configurations.The equivalent to an ultra-low-power, high-resolution, digital-to-analog converter is realized with the combination of two-PWM signals received from a microcontroller, the two conditioner circuits, and an active filter built with the integrated low-power op amp. The outputs of the two conditioner circuits provide a stable PWM amplitude over voltage supply and temperature variation. The wide bandwidth amplifier, in combination with a discrete transistor, converts a voltage input into a current output and allows HART and Foundation Fieldbus H1 signal modulation. The zero-offset operational amplifier and the low-drift voltage reference provide negligible error over wide temperature. The low-power operational amplifier and comparators provide building blocks for enhanced diagnostic features. Supply rail monitoring, output current readback, open circuit and failure detection are a few examples of diagnostic features. All these features, as well as ultra-low-power and high accuracy make the MAX12900 ideal for loop-powered smart sensor transmitters for industrial application.The MAX12900 is available in 5mm x 5mm 32-pin TQFN package and operates over a wide industrial temperature range of -40°C to +125°C.ApplicationsIndustrial Automation and Process ControlLoop-powered 4-20mA Current TransmitterRemote InstrumentationSmart Sensors
