AD7948BRZ-REEL Datasheet/PDFThe AD7948BRZ-REEL is a part of the Analog Device family of Digital to Analog Converters (DAC). These are devices which are used to convert digital signals into analog signals, typically for the purpose of providing control in different types of applications. The AD7948BRZ-REEL can be used in a wide range of applications, such as consumer electronics, instrumentation, automotive, and medical.
The AD7948BRZ-REEL is a 12-bit, unipolar DAC with a voltage reference. It has a voltage reference range of 2.5V to 5V and an output voltage range of 0V to 5V. It operates with a temperature range of −40°C to +85°C and has a typical power dissipation of 9mW. It is designed to interface directly with most microcontrollers via an SPI or I2C interface.
The AD7948BRZ-REEL has an auto-powerdown feature that reduces power consumption to 0.1µW. This allows low power operation and improved system battery life. The device has a power-on reset that ensures proper initialization of registers in the event of a sudden power-on or reset. It also features a Thermal Shutdown circuit which shuts down the device in case of an overtemperature condition.
The working principle of the AD7948BRZ-REEL is quite simple. When an input signal is applied, it converts the digital signal into an analog signal which is in turn transmitted to the output. The conversion is done using a SAR (Successive Approximation Register) architecture which provides a fast, accurate, and low power conversion. The device provides an output that is linearly and precisely proportional to the input signal.
The AD7948BRZ-REEL is a great choice for a wide range of applications. It is fast, accurate, and low power, which makes it ideal for consumer electronics, instrumentation, automotive, and medical applications. It is also an excellent choice for applications that require precise and low-power DAC performance.
