Характеристики

AD5302ARMZ, ЦАП 8-бит Dual Rail-to-Rail [MSOP-8]The AD5302ARMZ is a dual 8-bit buffered voltage output Digital-to-analog Converter (DAC) operates from a single 2.5 to 5.5V supply, consuming 230µA at 3V. Its on-chip output amplifier allows the outputs to swing rail-to-rail with a slew rate of 0.7V/µs. The AD5302 utilizes a versatile 3-wire serial interface that operates at clock rates up to 30MHz and is compatible with standard SPI®, QSPI™, MICROWIRE™ and DSP interface standards. The reference inputs can be configured as buffered or un-buffered inputs. The outputs of DAC can be updated simultaneously using the asynchronous LDAC input. The parts incorporate a power-on reset circuit, which ensures that the DAC outputs power-up to 0V and remain there until a valid write takes place to the device. The parts contain a power-down feature that reduces the current consumption of the devices to 200nA at 5V and provides software-selectable output loads while in power-down mode.

• Double-buffered input logic
• Guaranteed monotonic by design over all codes
• Simultaneous update of DAC outputs via LDAC
