Description

The AD5062, a member of ADI?s?nanoDAC? family, is a low power, single 16-bit unbuffered voltage-out DAC that operatesfrom a single 2.7 V to 5.5 V supply. The part offers a relative accuracy specification of ?1 LSB, and operation is guaranteed monotonic with a ?1 LSB DNL specification. The part uses 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. The reference for the AD5062 is supplied from an external VREF pin. A reference buffer is also provided on-chip. The part incorporates a power-on reset circuit that ensures the DAC output powers up to zero scale or mid-scale and remains there until a valid write takes place to the device. The part contains a power-down feature that reduces the current consumption of the device to typically 300 nA at 5 V and provides software-selectable output loads while in power-down mode. The part is put into power-down mode over the serial interface. Total unadjusted error for the part is <0.8 mV.This part exhibits very low glitch on power-up.PRODUCT HIGHLIGHTS Available in a tiny 8-lead SOT-23 package. 16-bit accurate, 1 LSB INL. Low glitch on power-up. High speed serial interface with clock speeds up to 30 MHz. Three power-down modes available to the user. Reset to known output voltage (zero-scale or mid-scale).APPLICATIONS Process control Data acquisition systems Portable battery-powered instruments Digital gain and offset adjustment Programmable voltage and current sources Programmable attenuators
