GENERAL DESCRIPTION
The AD5062, a member of ADI’s nanoDAC family, is a low
power, single 16-bit unbuffered voltage-out DAC that operates
from 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
1. Available in a tiny 8-lead SOT-23 package.
2. 16-bit accurate, 1 LSB INL.
3. Low glitch on power-up.
4. High speed serial interface with clock speeds up to 30 MHz.
5. Three power-down modes available to the user.
6. Reset to known output voltage (zero-scale or mid-scale).
