AD5061YRJZ-1500RL7

A low power, single 16-bit buffered voltage-out DAC that operates from a single 2.7V to 5.5V supply. The device offers a relative accuracy specification of ±4 LSB and operation is guaranteed monotonic with a ±1 LSB DNL specification. The device uses 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 for the device is supplied from an external VREF pin. A reference buffer is also provided on-chip. The device incorporates a power-on reset circuit that ensures the DAC output powers up to mid-scale or zero scale and remains there until a valid write takes place to the device. The device contains a power-down feature that reduces the current consumption of the device to typically 330nA at 5V and provides software-selectable output loads while in power-down mode. The device is put into power-down mode over the serial interface. Total unadjusted error for the device is < 3mV. This device exhibits very low glitch on power-up.
