ANALOG DEVICES AD5721BCPZ-RL7 Digital to Analogue Converter, 12 bit, 4 Wire, DSP, Serial

AD5721BCPZ-RL7 is a single channel, 12bit serial input, voltage output, digital-to-analogue converter (DAC). It uses a serial interface that operates at clock rates of upto 50MHz and is compatible with DSP and microcontroller interface standards. Double buffering allows the asynchronous updating of the DAC output. The input coding is user-selectable two complement or straight binary. The asynchronous reset function resets all registers to their default state. The output range is user selectable, via the RA[2:0] bits in the control register. It is used in applications such as industrial automation, instrumentation, data acquisition, open-/closed-loop servo control, process control, and programmable logic controllers.

• Integrated reference buffers, 1.8V logic compatibility
• DSP/microcontroller-compatible serial interface, robust 4kV HBM ESD rating
• Asynchronous updating via active-low LDAC, asynchronous active-low RESET to zero scale/midscale
• Differential nonlinearity is +0.5LSB maximum at (VDD1 = 4.75V to 30V, VSS1 = -16.5V to 0V)
• Total unadjusted error is +0.1% FSR maximum at (VDD1 = 4.75V to 30V, VSS1 = -16.5V to 0V)
• Digital-to-analogue glitch impulse is 8nV-sec typical at (VDD1 = 4.75V to 30V, VSS1 = -16.5V to 0V)
• Output noise is 35µV rms typical at (VDD1 = 4.75V to 30V, VSS1 = -16.5V to 0V)
• Signal-to-noise ratio is 92dB typ at (ambient, 2.5V external reference, BW = 20KHz, fOUT = 1KHz)
• Gain error is +0.1% FSR maximum at (VDD1 = 4.75V to 30V, VSS1 = -16.5V to 0V)
• Operating temperature range from -40°C to +125°C, 16-lead LFCSP package
