GENERAL DESCRIPTION
The AD5380 is a complete, single-supply, 40-channel, 14-bit
denseDAC® 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
2
C-compatible interface
that supports a 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.

voltage output DACs in the product portfolio.
