AD5390/AD5391/AD5392 Data Sheet
Rev. E | Page 4 of 44
GENERAL DESCRIPTION
The AD5390/AD5391 are complete single-supply, 16-channel,
14-bit and 12-bit DACs, respectively. The AD5392 is a complete
single-supply, 8-channel, 14-bit DAC. The devices are available
in either a 64-lead LFCSP or a 52-lead LQFP. All channels have
an on-chip output amplifier with rail-to-rail operation. All
devices include an internal 1.25/2.5 V, 10 ppm/°C reference, an
on-chip channel monitor function that multiplexes the analog
outputs to a common MON_OUT pin for external monitoring,
and an output amplifier boost mode that optimizes the output
amplifier slew rate.
The AD5390/AD5391/AD5392 contain a 3-wire serial interface
with interface speeds in excess of 30 MHz that are compatible
with SPI®, QSPI™, MICROWIRE™, and DSP interface standards
and an I
2
C-compatible interface supporting a 400 kHz data
transfer rate.
An input register followed by a DAC register provides double-
buffering, allowing DAC outputs to be updated independently
or simultaneously using the
LDAC
input. Each channel has a
programmable gain and offset adjust register, letting the user
fully calibrate any DAC channel.
Power consumption is typically 0.25 mA per channel.
