AD7302BRZ-REEL7

AD7302BRZ-REEL7 is a dual, 8-bit voltage out DAC that operates from a single +2.7V to +5.5V supply. Its on-chip precision output buffers allow the DAC outputs to swing rail to rail. The AD7302 has a parallel microprocessor and DSP-compatible interface with high speed registers and double buffered interface logic. Reference selection for AD7302 can be either an internal reference derived from the VDD or an external reference applied at the REFIN pin. Both DACs can be simultaneously updated using the asynchronous LDAC input and can be cleared by using the asynchronous CLR input. The low power consumption of this part makes it ideally suited to portable battery operated equipment. The power consumption is less than 10mW at 3.3V, reducing to 3µW in powerdown mode. Typical applications include portable battery powered instruments, digital gain and offset adjustment, programmable voltage and current sources and programmable attenuators.

• DAC power-down function
• Rail-to-rail operation
• Low power operation 3mA max at 3.3V
• Power-down to 1µA max at 25°C
• Available in 20 lead SOIC package
• Operating temperature range from -40°C to 105°C
