Digital to Analog Converters - DAC CMOS CONVERTER IC

The AD5593R has eight input/output (I/O) pins, which can beindependently configured as digital-to-analog converter (DAC)outputs, analog-to-digital converter (ADC) inputs, digital outputs,or digital inputs. When an I/O pin is configured as an analogoutput, it is driven by a 12-bit DAC. The output range of theDAC is 0 V to VREF or 0 V to 2 ? VREF. When an I/O pin isconfigured as an analog input, it is connected to a 12-bit ADCvia an analog multiplexer. The input range of the ADC is 0 V toVREF or 0 V to 2 ? VREF. The I/O pins can also be configured tobe general-purpose, digital input or output (GPIO) pins. Thestate of the GPIO pins can be set or read back by accessing theGPIO write data register and GPIO read configuration registers,respectively, via an I2C write or read operation.The AD5593R has an integrated 2.5 V, 20 ppm/?C reference thatis turned off by default and an integrated temperature indicatorthat gives an indication of the die temperature. The temperaturevalue is read back as part of an ADC read sequence.The AD5593R is available in 16-lead TSSOP and LFCSP, as wellas a 16-ball WLCSP, and operates over a temperature range of?40?C to +105?C.Applications Control and monitoring General-purpose analog and digital I/O

The LTC4227 offers ideal diode-OR and Hot Swap? functions for two power rails by controlling external Nchannel MOSFETs. MOSFETs acting as ideal diodes replace two high power Schottky diodes and the associated heat sinks, saving power and board area. A Hot Swap control MOSFET allows a board to be safely inserted and removed from a live backplane by limiting inrush current. The supply output is also protected against short-circuit faults with a fast acting current limit and internal timed circuit breaker.The LTC4227 regulates the forward voltage drop across the MOSFETs to ensure smooth current transfer from one supply to the other without oscillation. The ideal diodes turn on quickly to reduce the load voltage droop during supply switchover. If the input supply fails or is shorted, a fast turn-off minimizes reverse-current transients.The LTC4227 allows turn-on/off control, and reports fault and power good status for the supply.

The AD7794/AD7795 are low power, low noise, complete analog front ends for high precision measurement applications. They contain a low noise, 24-/16-bit ?-? ADC with six differential inputs. The on-chip low noise instrumentation amplifier means that signals of small amplitude can be interfaced directly to the ADC.Each device contains a precision, low noise, low drift internal band gap reference, and can also accept up to two external differential references. Other on-chip features include programmable excitation current sources, burnout currents, and a bias voltage generator that is used to set the common-mode voltage of a channel to AVDD/2. The low-side power switch can be used to power down bridge sensors between conversions, minimizing the system?s power consumption. The AD7794/AD7795 can operate with either an internal clock or an external clock. The output data rate from each part can vary from 4.17 Hz to 470 Hz.Both parts operate with a power supply from 2.7 V to 5.25 V.
