The AD7845JR is an integrated circuit (IC) component produced by Analog Devices. This IC is a high-speed, microprocessor-compatible, 8-bit digital-to-analog converter (DAC) with an input/output range of 0 to +5 volts. It offers exceptional performance and versatility for a wide range of application areas, including industrial automation, data acquisition systems, and process control.
One of the key features of the AD7845JR is its 8-bit resolution, providing a fine level of analog output precision. Moreover, it supports both serial and parallel interface modes, allowing flexibility in communication with microcontrollers and other digital systems. The IC incorporates a high-speed input latch that enables independent read/write operations to enhance system performance.
The AD7845JR operates on a single power supply, typically ranging from +4.5 to +5.5 volts, which makes it compatible with a variety of power sources. It also offers low power consumption, ensuring efficient operation even under power-constrained conditions. Furthermore, it features a power-on-reset (POR) circuitry, allowing reliable initialization during system start-up.
This IC component incorporates an internal reference voltage source, eliminating the need for an external reference. This on-chip reference enhances system integration and reduces external component count, making it ideal for space-constrained applications. Additionally, the AD7845JR provides a precision external reference input if required by the application
