General Description
The MAX14527/MAX14528 overvoltage protection devices feature a low 100mΩ (typ) RON internal FET and protect low-voltage systems against voltage faults up to +28V. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected components.
The overvoltage protection threshold can be adjusted with optional external resistors to any voltage between 4V and 8V. With the OVLO input set below the external OVLO select voltage, the MAX14527/MAX14528 automatically choose the internal ±2.5% accurate trip thresholds. The internal overvoltage thresholds (OVLO) are preset to 5.75V typical (MAX14527) or 6.76V typical (MAX14528). The MAX14527/MAX14528 are also protected against overcurrent events with an internal thermal shutdown.
The MAX14527/MAX14528 are offered in a small, 8-pin TDFN-EP package and operate over the -40°C to +85°C extended temperature range.

GENERAL DESCRIPTION
The AD5762R is a dual, 16-bit, serial input, bipolar voltage output digital-to-analog converter that operates from supply voltages of ±11.4 V up to ±16.5 V. Nominal full-scale output
range is ±10 V. The AD5762R provides integrated output amplifiers, reference buffers and proprietary power-up/powerdown control circuitry. The parts also feature a digital I/O port,
which is programmed via the serial interface and an analog temperature sensor. The part incorporates digital offset and gain adjust registers per channel.
The AD5762R is a high performance converter that offers guaranteed monotonicity, integral nonlinearity (INL) of ±1 LSB, low noise, and 10 μs settling time. The AD5762R includes an
on-chip 5 V reference with a reference tempco of 10 ppm/°C maximum. During power-up (when the supply voltages are changing), VOUT is clamped to 0 V via a low impedance path.
The AD5762R uses a serial interface that operates at clock rates of up to 30 MHz and is compatible with DSP and microcontroller interface standards. Double buffering allows
the simultaneous updating of all DACs. The input coding is programmable to either twos complement or offset binary formats. The asynchronous clear function clears all DAC
registers to either bipolar zero or zero scale depending on the coding used. The AD5762R is ideal for both closed-loop servo control and open-loop control applications. The AD5762R is
available in a 32-lead TQFP, and offers guaranteed specifications over the −40°C to +85°C industrial temperature range. See Figure 1, the functional block diagram.
