в—Џ The DAC7642 and DAC7643 are dual channel, 16-bit, voltage output Digital-to-Analog Converters (DACs) which provide 15-bit monotonic performance over the specified temperature range. They accept 16-bit parallel input data, have
double-buffered DAC input logic (allowing simultaneous update of all DACs), and provide a readback mode of the
internal input registers. Programmable asynchronous reset
clears all registers to a mid-scale code of 8000H (DAC7642)
or to a zero-scale code of 0000H (DAC7643). These DACs
can operate from a single +5V supply or from +5V and –5V
supplies, providing an output range of 0 to +2.5V or –2.5V to
+2.5V, respectively. LOW POWER: 4mW
UNIPOLAR OR BIPOLAR OPERATION
SETTLING TIME: 10Вµs to 0.003% FSR
15-BIT LINEARITY AND MONOTONICITY:
–40°C to +85°C ● RESET TO MID-SCALE (DAC7642) OR
ZERO-SCALE (DAC7643)
