в—Џ The DAC7632 is a 16-bit, dual channel, voltage output,
Digital-to-Analog Converter (DAC) which provides 15-bit
monotonic performance over the specified temperature range.
The device accepts 24-bit serial input data, has doublebuffered DAC input logic (allowing simultaneous update of
both DACs), and provides a serial data output for daisychaining multiple devices. A programmable asynchronous
reset clears all registers to a mid-scale code of 8000H or to
a zero-scale code of 0000H. The DAC7632 can operate from
a single +5V supply or from +5V and –5V supplies, providing
an output range of 0V to +2.5V or –2.5V to +2.5V, respectively. LOW POWER: 4mW
UNIPOLAR OR BIPOLAR OPERATION
SETTLING TIME: 10Вµs to В±0.003% FSR
15-BIT LINEARITY AND MONOTONICITY:
–40°C to +85°C ● PROGRAMMABLE RESET TO MID-SCALE
OR ZERO-SCALE
в—Џ DOUBLE-BUFFERED DATA INPUTS APPLICATIONS Low power and small size per DAC make the DAC7632
ideal for industrial process control, data acquisition systems, and closed-loop servo-control. The DAC7632 is available in an LQFP-32 package and specified over a –40°C to
+85В°C temperature range. в—Џ PROCESS CONTROL …
