AD7805BRSZ

AD7805BRSZ is a quad 10bit digital-to-analogue converter with parallel load capabilities. It operates from a +3.3V to +5V(±10%) power supply and incorporates an on-chip reference. It provides output signals in the form of VBIAS ± VSWING. VSWING is derived internally from VBIAS. On-chip control registers include a system control register and channel control registers. The system control register has control over all DACs in the package. The channel control registers allow individual control of DACs. The complete transfer function of each individual DAC can be shifted around the VBIAS point using an on-chip Sub DAC. All DACs contain double buffered data inputs, which allow all analogue outputs to be simultaneously updated using the asynchronous LDAC input. Typical applications include optical disk drives, instrumentation and communication systems, process control and voltage setpoint control, trim potentiometer replacement and automatic calibration.

• Features power-down mode, power-on reset, standby mode (all DACs/individual DACs)
• Low power all CMOS construction
• Double buffered DAC registers
• Dual external reference capability
• Relative accuracy of ±3LSB
• Available in 28 lead SSOP package
• Operating temperature range from -40°C to 85°C
