Figure 2. AD5024/AD5044/AD5064 with Individual Reference Pins
GENERAL DESCRIPTION
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
parts 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 power-
down mode. Total unadjusted error for the parts is <2 mV.
PRODUCT HIGHLIGHTS
1. Quad channel available in 14-/16-lead TSSOP packages.
2. 16-bit accurate, 1 LSB INL.
3. High speed serial interface with clock speeds up to 50 MHz.
4. Reset to known output voltage (zero scale or midscale).
