 Industry's Most Accurate Voltage/Current Output Driver for Industrial Control Systems The AD5750 and AD5751 are single channel, high performance, voltage/current output drivers featuring hardware- or software-programmable output ranges. The AD5750 operates from industry-standard ±12 V to ±24 V supplies and delivers 5 ppm/°C output drift, 0.01% linearity, and 0.1% TUE. The output configuration is software-selectable from options of 5 V, 10 V, >±5 V, and ±10 V in voltage mode and 4 mA to 20 mA, 0 mA to 20 mA, 0 mA to 24 mA, ±20 mA, and ±24 mA in current mode. All output spans include an additional overrange setting. Analog outputs are short-circuit and open-circuit protected and can drive capacitive loads of 1 µF and inductive loads of 0.1 H. The AD5750 integrates packet error checking (PEC) to verify that interface data has been correctly received in the presence of noise—useful in industrial environments where data communications corruption can occur. The device also includes an asynchronous CLEAR pin that sets the outputs to zero-scale/ midscale in voltage mode or the low end of the selected current range in current-mode. The AD5751 operates with single supplies of 12 V to 60 V and features unipolar voltage and current mode output configurations.
AD5750/AD5751 Features
Highest Precision, Accurate, Low Voltage Buffered Quad DAC Offers 1 LSB INL at 16 Bits Ideal for precision multichannel input/output systems, the AD5064 is a quad 16-bit DAC with 16-bit accuracy over a 0 V to 5 V output span—delivering a TUE of less than ±2 mV in a compact 14-lead TSSOP package. The device is also available in a 16-lead TSSOP with individual reference pins allowing each DAC the flexibility to be driven with a different reference voltage, if necessary. In addition, the device is extremely flexible and provides many convenient control features such as pin-selectable reset/power-on to midscale or zero-scale, hardware LDAC and CLEAR pins, and a programmable CLEAR function to allow the user to select clear options. Other features include LDAC override to allow only selected channels to be synchronously updated, an SDO pin to allow daisy-chaining of multiple devices, and a per channel power-down feature. Pincompatible 12-bit and 14-bit versions are also available—ensuring easy upgrade or downgrade options. To design a complete multichannel PLC analog output module system, the AD5750/AD5751 output drivers are an ideal choice with the AD5064 family of DACs.
