The AD7834BR is an integrated circuit (IC) component manufactured by Analog Devices. It is a quad 14-bit digital-to-analog converter (DAC) that is commonly used in various applications such as data acquisition systems, programmable logic controllers, and process automation equipment. Now, let's dive into the key features of this IC component.
1. Quad DAC: The AD7834BR consists of four separate DACs, each with a resolution of 14 bits. This allows for the simultaneous conversion of digital signals to analog outputs, making it ideal for multi-channel applications.
2. High Accuracy: The IC offers exceptional accuracy with a maximum integral nonlinearity (INL) error of only ±2 LSB (Least Significant Bit). This ensures precise analog output representation of digital signals, resulting in reliable system performance.
3. Output Configuration: Each DAC channel can be configured independently as either voltage or current output. For voltage outputs, the AD7834BR provides a voltage output range of 0 to VREF. On the other hand, for current outputs, it supports a range of 4 mA to 20 mA with a programmable current reference.
4. Programmable Reference Voltage: The IC allows the selection of either an external reference voltage or an on-chip programmable reference voltage. The on-chip reference voltage is set using a reference input pin (VREF). This flexibility enables compatibility with various system requirements
