AD5612ACPZ-2-RL7

AD5612ACPZ-2-RL7 is a single 10bit buffered voltage-out, nanoDAC® digital-to-analogue converter (DAC). The reference for AD5612 derives from the power supply inputs to give the widest dynamic output range. This device incorporates a power-on reset circuit that ensures the DAC output powers upto 0V and remains there until a valid write takes place to the device. This device contains a power-down feature that reduces the current consumption of the devices to <lt/>150nA at 3V and provides software-selectable output loads while in power-down mode. This device is put into power-down mode over the serial interface. The low power consumption of the AD5612 in normal operation makes them ideally suited for use in portable, battery-operated equipment. It is used in applications such as process control, data acquisition systems, portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, and programmable attenuators.

• Output voltage settling time is 6µs typical at (code ¼ to ¾, VDD = 2.7V to 5.5V)
• Slew rate is 0.5V/µs typical at (VDD = 2.7V to 5.5V, RL = 2Kohm to GND)
• Digital-to-analogue glitch impulse is 5nV-sec typical at (VDD = 2.7V to 5.5V, RL = 2Kohm to GND)
• Output noise spectral density is 120nV/Hz typical at (DAC code = midscale, 10KHz)
• Operating temperature range from -40°C to +125°C, 6-lead LFCSP package
