GENERAL DESCRIPTION
The AD5381 is a complete, single-supply, 40-channel, 12-bit
denseDAC® available in a 100-lead LQFP package. All 40 channels
have an on-chip output amplifier with rail-to-rail operation.
The AD5381 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,
which allows optimization of the amplifier slew rate. The AD5381
contains a double-buffered parallel interface featuring 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 independ-
ently 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 mode disabled.
