Product Information
Product Overview
AD5791 is a single 20bit, unbuffered voltage-output digital to-analogue converter (DAC) that operates from a bipolar supply of up to 33V. This accepts a positive reference input in the range 5V to VDD -2.5V and a negative reference input in the range VSS + 2.5V to 0V. The device uses a versatile 3-wire serial interface that operates at clock rates up to 35MHz and that is compatible with standard serial peripheral interface (SPI), QSPI™, MICROWIRE™, and DSP interface standards. The device incorporates a power-on reset circuit that ensures the DAC output powers up to 0V and in a known output impedance state and remains in this state until a valid write to the device takes place. The device provides an output clamp feature that places the output in a defined load state. Application includes medical instrumentation, test and measurement, industrial control, high end scientific and aerospace instrumentation.
- Resolution is 20bits (min, VDD = 12.5V to 16.5V)
- Integral nonlinearity error is ±2LSB (typ, VDD = 12.5V to 16.5V)
- Differential nonlinearity error is ±0.5LSB (VREFP = +10V, VREFN = -10V)
- Full-scale error is ±0.1LSB (typ, VREFP = +10V, VREFN = -10V)
- Zero-scale error is ±0.1LSB (typ, VREFP = +10V, VREFN = -10V)
- Gain error is ±0.3ppm FSR (typ, VREFP = +10V, VREFN = −10V)
- Output slew rate is 50V/µs (typ, VDD = 12.5V to 16.5V)
- Output voltage noise is 1.1µV p-p (typ, DAC code = midscale, 0.1Hz to 10Hz bandwidth)
- Total harmonic distortion is 97dB (typ, 1KHz tone, 10KHz sample rate)
- 20 lead TSSOP package, operating temperature range from -40°C to +125°C
