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.
