AD5302ARMZ
2.5 V to 5.5 V, 230 μA, Dual Rail-to-Rail, Voltage Output 8-/10-/12-Bit DACs
数模转换器- DAC DUAL 8-BIT VTG OUT IC
GENERAL DESCRIPTION AD5302ARMZ
The AD5302/AD5312/AD5322 are dual 8-, 10-, and 12-bit
buffered voltage output DACs in a 10-lead MSOP that operate
from a single 2.5 V to 5.5 V supply, consuming 230 μA at 3 V.
Their on-chip output amplifiers allow the outputs to swing railto-rail
with a slew rate of 0.7 V/μs. The AD5302/AD5312/AD5322
utilize a versatile 3-wire serial interface that operates at clock
rates up to 30 MHz and is compatible with standard SPI®,
QSPI™, MICROWIRE™, and DSP interface standards.
