GENERAL DESCRIPTION
The AD5380 is a complete, single-supply, 40-channel, 14-bit
DAC available in a 100-lead LQFP package. All 40 channels
have an on-chip output amplifier with rail-to-rail operation.
The AD5380 includes a programmable internal 1.25 V/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 allows optimization of the amplifier slew rate. The AD5380
contains a double-buffered parallel interface that features a
20 ns WR pulse width, an SPI-, QSPI-, -MICROWIRE, -DSP
compatible serial interface with interface speeds in excess
of 30 MHz, and an I
400 kHz data transfer rate.

An input register followed by a DAC register provides double
buffering, allowing the DAC outputs to be updated indepen-
dently or simultaneously using the LDAC input.
Each channel has a programmable gain and offset adjust
register that allows the user to fully calibrate any DAC chan-
nel. Power consumption is typically 0.25 mA/channel with
boost off.
Table 1 and Table 2 show other high channel count low voltage,
single supply and bipolar, dual supply, voltage output DACs
in product portfolio.
