Description
AD5601/AD5611/AD5621 2.7 V to 5.5 V, <100 µA, 8-, 10-, 12-bit
nanoDAC with SPI® interface in tiny
LFCSP and SC70 packages
GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The AD5602/AD5612/AD5622, members of the nanoDAC
family, are single 8-, 10-, 12-bit buffered voltage-out DACs that
operate from a single 2.7 V to 5.5 V supply, consuming <100 µA
at 5 V. These DACs come in tiny LFCSP and SC70 packages.
Each DAC contains an on-chip precision output amplifier that
allows rail-to-rail output swing to be achieved.
The AD5602/AD5612/AD5622 use a 2-wire I2C-compatible
serial interface that operates in standard (100 kHz), fast
(400 kHz), and high speed (3.4 MHz) modes.
1. Available in 6-lead LFCSP and SC70 packages.
2. Maximum 100 µA power consumption, single-supply
operation. These parts operate from a single 2.7 V to 5.5 V
supply, typically consuming 0.2 mW at 3 V and 0.4 mW at
5 V, making them ideal for battery-powered applications.
3. The on-chip output buffer amplifier allows the output of
the DAC to swing rail-to-rail with a typical slew rate of
0.5 V/µs.
The references for AD5602/AD5612/AD5622 are derived from
the power supply inputs to give the widest dynamic output range.
Each part incorporates a power-on reset circuit that ensures the
DAC output powers up to 0 V and remains there until a valid
write takes place to the device. The parts contain a power-down
feature that reduces the current consumption of the devices to
<150 nA at 3 V and provides software-selectable output loads
while in power-down mode. The parts are put into power-down
mode over the serial interface. The low power consumption of
the AD5602/AD5612/AD5622 in normal operation makes them
ideally suited for use in portable battery-operated equipment. The
typical power consumption is 0.4 mW at 5 V.
4. Reference derived from the power supply.
5. Standard, fast, and high speed mode I2C interface.
6. Designed for very low power consumption.
7. Power-down capability. When powered down, the DAC
typically consumes <150 nA at 3 V.
8. Power-on reset and brownout detection.
