DAC8832
SBAS380A – FEBRUARY 2006 – REVISED APRIL 2006
16-Bit, Ultra-Low Power, Voltage-Output
Digital-to-Analog Converter
• 16-Bit Resolution
The DAC8832 is
a
single,
16-bit,
serial-input,
voltage-output
digital-to-analog
converter
(DAC)
• 2.7 V to 5.5 V Single-Supply Operation
operating from a single 3 V to 5 V power supply. The
• Very Low Power: 15 µW for 3 V Power
DAC8832 provides excellent linearity (1 LSB INL),
• High Accuracy, INL: 1 LSB
low glitch, low noise, and fast settling (1.0
µS to 1/2
• Low Glitch: 10 nV-s
LSB
of
full-scale
output)
over
the
specified
temperature range of –40
°C to +85°C. The output is
• Low Noise: 18n V/√Hz
unbuffered, which reduces the power consumption
• Fast Settling: 1.0 µS
and the error introduced by the buffer.
• Fast SPI™ Interface, up to 50 MHz
This device features a standard high-speed (clock up
• Reset to Mid-Code
to 50MHz), 3 V or 5 V SPI serial interface to
• Schmitt-Trigger Inputs for Direct Optocoupler
communicate with the DSP or microprocessors.
Interface
The DAC8832 provides unipolar or bipolar output
(
±V
REF) when working with an external buffer, and is
reset to mid-code after power-up. For optimum
• Portable Equipment
performance, a set of Kelvin connections to the
external reference and the analog ground input are
• Automatic Test Equipment
provided.
• Industrial Process Control
The DAC8832 is available in a QFN-14 package,
• Data Acquisition Systems
and is pin-to-pin compatible with the DAC8831IRGY,
• Optical Networking
which is reset to zero-code after power-up.
