GENERAL DESCRIPTION
The AD5301/AD5311/AD53211 are single 8-/10-/12-bit, buff-
ered, voltage-output DACs that operate from a single 2.5 V to
5.5 V supply, consuming 120 μA at 3 V. The on-chip output
amplifier allows rail-to-rail output swing with a slew rate of
0.7 V/μs. It uses a 2-wire (I2C-compatible) serial interface that
operates at clock rates up to 400 kHz. Multiple devices can share
the same bus.
The reference for the DAC is derived from the power supply
inputs and thus gives the widest dynamic output range. These
parts incorporate a power-on reset circuit, which ensures that
the DAC output powers up to 0 V and remains there until a
valid write takes place. The parts contain a power-down feature
that reduces the current consumption of the device to 50 nA at
3 V and provides software-selectable output loads while in
power-down mode.
The low power consumption in normal operation makes these
DACs ideally suited to portable battery-operated equipment. The
power consumption is 0.75 mW at 5 V and 0.36 mW at 3 V,
reducing to 1 μW in all power-down modes.
