GENERAL DESCRIPTION
The AD5761/AD5721 are single channel, 16-/12-bit serial input, voltage output, digital-to-analog converters (DACs).
They operate from single supply voltages from +4.
75 V to +30 V or dual supply voltages from −16.
5 V to 0 V VSS and +4.
75 V to +16.
5 V VDD.
The integrated output amplifier and reference buffer provide a very easy to use, universal solution.
The devices offer guaranteed monotonicity, integral nonlinearity (INL) of ±2 LSB maximum, 35 nV/√Hz noise, and 7.
5 μs settling time on selected ranges.
The AD5761/AD5721 use a serial interface that operates at clock rates of up to 50 MHz and are compatible with DSP and microcontroller interface standards.
Double buffering allows the asynchronous updating of the DAC output.
The input coding is user-selectable twos 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.
The devices available in the 16-lead TSSOP and in the 16-lead LFCSP offer guaranteed specification...
