в—Џ MSOP-8 PACKAGE The DAC8501 is a low-power, single, 16-bit buffered voltage
output Digital-to-Analog Converter (DAC) optimized for multiplying operation. Its on-chip precision output amplifier allows
rail-to-rail output swing to be achieved. The DAC8501 uses a
versatile 3-wire serial interface that operates at clock rates up
to 30MHz and is compatible with standard SPIв„ў, QSPIв„ў,
Microwireв„ў, and Digital Signal Processor (DSP) interfaces. The low-power consumption of this part in normal operation
makes it ideally suited to portable battery-operated equipment. The power consumption is 1.2mW at 5V reducing to
1ВµW in power-down mode. APPLICATIONS
