GENERAL DESCRIPTION
The AD5383 is a complete, single-supply, 32-channel, 12-bit
denseDAC® available in a 100-lead LQFP package. All 32
channels have an on-chip output amplifier with rail-to-rail
operation. The AD5383 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 AD5383 features
• Double-buffered parallel interface with a 20 ns
WR
pulse
width.
• SPI-/QSPI-/MICROWIRE-/DSP-compatible serial
interface with interface speeds in excess of 30 MHz.
• 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 channel.
With boost off, power consumption is typically 0.25 mA/channel.
Table 1 and Table 2 show additional products featuring high
channel count, low voltage, single-supply operation, and bipolar
voltage output operation.
