Description
The MCP4901/4911/4921 devices are single channel
8-bit, 10-bit and 12-bit buffered voltage output
Digital-to-Analog Converters (DACs), respectively. The
devices operate from a single 2.7V to 5.5V supply with
an SPI compatible Serial Peripheral Interface. The user
can configure the full-scale range of the device to be
VREF or 2*VREF by setting the gain selection option bit
(gain of 1 of 2).
The user can shut down the device by setting the Con-
figuration Register bit. In Shutdown mode, most of the
internal circuits are turned off for power savings, and
the output amplifier is configured to present a known
high resistance output load (500 k
typical.
The
devices
include
double-buffered
registers,
allowing synchronous updates of the DAC output using
the LDAC pin. These devices also incorporate a
Power-on Reset (POR) circuit to ensure reliable power-
up.
The devices utilize a resistive string architecture, with
its inherent advantages of low Differential Non-Linear-
ity (DNL) error and fast settling time. These devices are
specified
over
the
extended
temperature range
(+125°C).
The devices provide high accuracy and low noise
performance for consumer and industrial applications
where calibration or compensation of signals (such as
temperature, pressure and humidity) are required.
The MCP4901/4911/4921 devices are available in the
PDIP, SOIC, MSOP and DFN packages.
