Nano DAC™

Process control Data acquisition systems Portable battery-powered instruments Digital gain and offset adjustment Programmable voltage and current sources Programmable attenuators

Quad channel available in 14-/16-lead TSSOPs. 16-bit accurate, 1 LSB INL. High speed serial interface with clock speeds up to 50 MHz. Reset to known output voltage (zero scale or midscale).

The AD5024/AD5044/AD5064/AD5064-1 are low power, quad 12-/14-/16-bit buffered voltage output nanoDAC® converters that offer relative accuracy specifications of 1 LSB INL and 1 LSB DNL with the AD5024/AD5044/AD5064 individual reference pin and the AD5064-1 common reference pin options. The AD5024/AD5044/AD5064/AD5064-1 can operate from a single 4.5 V to 5.5 V supply. The AD5024/AD5044/AD5064/AD5064-1 also offer a differential accuracy specification of ±1 LSB. The devices use a versatile 3-wire, low power Schmitt trigger serial interface that operates at clock rates up to 50 MHz and is compati- ble with standard SPI, QSPI™, MICROWIRE, and DSP interface standards. Integrated reference buffers and output amplifiers are also provided on-chip. The AD5024/AD5044/AD5064/AD5064-1 incorporate a power-on reset circuit that ensures the DAC output powers up to zero scale or midscale and remains there until a valid write takes place to the device. The AD5024/AD5044/ AD5064/AD5064-1 contain a power-down feature that reduces the current consumption of the device to typically 400 nA at 5 V and provides software selectable output loads while in powerdown mode. Total unadjusted error for the devices is <2 mV.
