AD5322BRM-REEL7

2.5 V至5.5 V ， 230 μA ，双通道，轨到轨，电压输出8位/ 10位/ 12位DAC 2.5 V to 5.5 V, 230 μA, Dual Rail-to-Rail, Voltage Output 8-/10-/12-Bit DACs

Product Details

The AD5302/AD5312/AD5322 are dual 8-, 10- and 12-bit buffered voltage output DACs in a 10-lead µSOIC package 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 rail-to-rail with a slew rate of 0.7 V/µs. The AD5302/ AD5312/AD5322 utilize a versatile 3-wire serial interface which operates at clock rates up to 30 MHz and is compatible with standard SPI™, QSPI™, MICROWIRE™ and DSP interface standards.
