The AD7564AR-B is a low power, high accuracy 12-bit digital-to-analog converter (DAC). It is designed for use in data acquisition systems and industrial control systems and can handle upper dynamic range of 4.096V. It features a fully user-programmable input range and fast settling time of only 80μs. This low voltage DAC uses an advanced CMOS design and offers excellent monotonicity, allowing it to be used in applications requiring accurate analog signal generation.

The AD7564AR-B is capable of providing precision attenuation, direct digital synthesis (DDS) and automatic gain control (AGC). This device features a single supply operation that makes it suitable for batter powered applications, high Voltage Accuracy and low noise. The 12-bit resolution makes it ideal for applications where high-resolution digital data needs to be converted to precise analog signals. Additionally, the low power operation and low output impedance reduces power dissipation.

The AD7564AR-B utilizes a simple 3-wire serial interface that enables the user to program the device. The serial interface consists of a serial clock (SCK), a data in (DIN) and a chip select (CS) pin. The SCK is used to provide the clock signal for shifting data into the 16-bit data register and the CS pin is used to select the desired device. The AD7564AR-B can be operated in single write, multiple write and multiple read modes. The digital data is output via the 12-bit DAC data outputs with 0V represented by digital zero code.

The AD7564AR-B provides Hardware Resetto initialize or restore the digital output states to pre- defined values. Additionally, the AD7564AR-B’s shutdown feature, when activated, disables the DAC output to reduce power consumption, making this device ideal for battery powered applications.

The AD7564AR-B features a wide range of user-programmable features. The device supports programmable register for full/half-scale user-defined output range and cycle-by-cycle functionality. The built-in power on reset feature maintains last programmed conditions when power is re-applied, while the range limit feature prevents the DAC outputs from exceeding safe levels. Additionally, the AD7564AR-B supports both unipolar and bipolar input range (zero conflict) and it is capable of reading back the value of the DAC register.

The AD7564AR-B is an ideal solution for applications requiring high accuracy and low power consumption such as medical instrumentation and other precision data acquisition systems. This DAC is a great choice for applications where digital data needs to be converted to precise analog signals. It is designed for applications requiring low power and fast conversion times, making it a great choice for battery-powered, low-power and automated systems.
