Product Details
●The AD5040, a member of the _nano_DAC® family, is a single full accurate 14-bit buffered voltage out DAC in a SOT-23
●By combining a 14-bit DAC and high performance output buffer in a SOT-23, the AD5040 delivers a maximum 1 LSB INL linearity error, making it ideal for high performance applications such as open loop control or precision gain and offset. The part utilizes a versatile three-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI™, QSPI™, MICROWIRE™ and DSP interface standards. The reference for the AD5040 is supplied from an external REF pin with a reference buffer provided on chip to simplify application of the device. The part incorporates a power-on-reset circuit that ensures the DAC output powers up to zero volts and remains there until a valid write takes place to the device. The part also contains a power-down feature that reduces the current consumption of the device to 1 µA at 5 V and provides software selectable output loads while in power-down mode. Power-down mode is activated over the serial interface with very low glitch on power up.
