1 / 17 page Full Accurate 14/16 Bit Vout nanoDacTM, Buffered, 3V/5V, Sot 23 Preliminary Technical Data AD5040/AD5060 FEATURES Single 14/16-Bit DAC, 1 Lsb inl. 1.8 Volt Digital Interface Capability Power-On-Reset to Zero Volts/Mid Scale Three Power-Down Functions Low Power Serial Interface with Schmitt- Triggered Inputs 8-Lead Sot23 Low Power Operation Fast Settling. Low Glitch on Powerup. APPLICATIONS Process Control Data Acquisition Systems Portable Battery Powered Instruments Digital Gain and Offset Adjustment Programmable Voltage and Current Sources Programmable Attenuators GENERAL DESCRIPTION The AD5040/AD5060, members of the nanoDAC TM family, are single 14/16-bit buffered voltage out DACs. Both parts are available in a 8ld Sot23. The AD5040 can be operated from 2.7-5.5V and the AD5060 can be operated at 3V/5V. 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/AD5060 is supplied from an external REF pin. A reference buffer is also provided on chip. The parts incorporate a power-on-reset circuit that ensures that the DAC output powers up to zero volts/ mid scale and remains there until a valid write takes place to the device. The parts also contain a power-down feature that reduces the current consumption of the device to 50nA 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 <1mV. These parts also provide a very low glitch on power-up.
