AD5737Quad Channel, 12-Bit, Serial Input, 4-20mA Output DAC with Dynamic Power Control and HART Connectivity | Integrated Circuits (ICs) | 2 | Active | The AD5737 is a quad-channel current output DAC that operates with a power supply range from 10.8 V to 33 V. On-chip dynamic power control minimizes package power dissipation by regulating the voltage on the output driver from 7.4 V to 29.5 V using a dc-to-dc boost converter optimized for minimum on-chip power dissipation.Each channel has a corresponding CHART pin so that HART signals can be coupled onto the current output of the AD5737.The AD5737 uses a versatile 3-wire serial interface that operates at clock rates of up to 30 MHz and is compatible with standard SPI, QSPI™, MICROWIRE®, DSP, and microcontroller interface standards. The serial interface also features optional CRC-8 packet error checking, as well as a watchdog timer that monitors activity on the interface.For a 16 bit equivalent solution, look at the AD5757.

The part incorporates digital offset and gain adjust registers per channel.The AD5744R is a high performance converter that provides guaranteed monotonicity, integral nonlinearity (INL) of ±1 LSB, low noise, and 10 μs settling time. The AD5744R includes an on-chip 5 V reference with a reference temperature coefficient of 10 ppm/°C maximum. During power-up when the supply voltages are changing, VOUTx is clamped to 0 V via a low impedance path.The AD5744R is based on theiCMOS®technology platform, which is designed for analog systems designers within industrial/instrumentation equipment OEMs who need high performance ICs at higher voltage levels.iCMOS enables the development of analog ICs capable of 30 V and operation at ±15 V supplies, while allowing reductions in power consumption and package size, coupled with increased ac and dc performance.The AD5744R 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 DATA registers to either bipolar zero or zero scale, depending on the coding used. The AD5744R is ideal for both closed-loop servo control and open-loop control applications. The AD5744R is available in a 32-lead TQFP and offers guaranteed specifications over the −40°C to +85°C industrial temperature range (see Figure 1 for the functional block diagram).APPLICATIONSIndustrial automationOpen-loop/closed-loop servo controlProcess controlData acquisition systemsAutomatic test equipmentAutomotive test and measurementHigh accuracy instrumentation |

AD5753Single-Channel, 16-Bit Current and Voltage Output DAC with Dynamic Power Control and HART Connectivity | Data Acquisition | 2 | Active | The AD5753 is a single-channel, voltage and current output digital-to-analog converter (DAC) that operates with a power supply range from a minimum of −33 V on AVSSto a maximum of +33 V on AVDD1with a maximum operating voltage of 60 V between the two rails. On-chip dynamic power control (DPC) minimizes package power dissipation.
