LTC2755AIUP-16#PBF

LTC2755AIUP-16#PBF is a quad, 16bit multiplying parallel-input, current-output DAC. These DACs operates from a single 2.7V to 5.5V supply and is all guaranteed monotonic over temperature. These SoftSpan™ DACs offer six output ranges-two unipolar and four bipolar-that can be programmed through the parallel interface, or pin strapped for operation in a single range. The LTC2755 DACs use a bidirectional input/output parallel interface that allows readback of any internal register, including the DAC output span settings. A power-on reset circuit resets the DAC outputs to 0V when power is initially applied. A logic low on the CLR pin asynchronously clears the DACs to 0V in any output range. Applications include high-resolution offset and gain adjustment, process control and industrial automation, automatic test equipment, data acquisition systems.

• Guaranteed monotonic over temperature, 2.7V to 5.5V single supply operation
• Parallel interface with readback of all registers, power-on reset to 0V
• Asynchronous CLR pin clears DAC outputs to 0V in any output range
• Integral nonlinearity is ±0.4LSB typical at (VDD = 5V, VREF = 5V, TA = 25°C)
• Gain error is ±2LSB typical at (VDD = 5V, VREF = 5V, TA = 25°C)
• Total Harmonic Distortion is -80dB typical at (multiplying, VDD = 5V, VREF = 5V, TA = 25°C)
• Output noise voltage density is 13nV/√Hz typical at (VDD = 5V, VREF = 5V, TA = 25°C)
• VDD supply current is 1μA maximum at (digital inputs = 0V or VDD)
• Reference multiplying BW is 2MHz typ at (0V to 5V range, VREF = 3VRMS, code = full scale, -3dB BW)
• Operating temperature range from -40°C to 85°C, 64-lead plastic QFN package
