GENERAL DESCRIPTION
The AD5380 is a complete single supply, 40-channel, 14-
bit DAC available in 100-lead LQFP package. All
40-channels have an on-chip output amplifier with rail-to-
rail operation. The AD5380 includes an internal 1.25/
2.5V, 10ppm/°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 the amplifier settling
time to be optimized. The AD5380 contains a double
buffered parallel interface featuring a
WR
pulse width of
20ns, a serial interface compatible with SPI
TM
, QSPI
TM
,
MICROWIRE
TM
and DSP interface standards with
interface speeds in excess of 30MHz and an I2C
compatible interface supporting 400kHz data transfer rate.
An input register followed by a DAC register provides
double buffering allowing the DAC outputs to be updated
independantly or simultaneously using the
LDAC
input.
Each channel has a programmable gain and offset adjust
register allowing the user to fully calibrate any DAC Channel.
Power consumption is typically 0.3mA/channel.
*Protected by U.S. Patent Nos. 5,969,657; other patents pending.
