DAC8552
SLAS430 – JULY 2006
16-BIT, DUAL CHANNEL, ULTRA-LOW GLITCH VOLTAGE OUTPUT
DIGITAL-TO-ANALOG CONVERTER
FEATURES
DESCRIPTION
• Relative Accuracy: 4LSB
The DAC8552 is a 16-bit, dual channel, voltage
• Glitch Energy: 0.15nV-s
output digital-to-analog converter (DAC) offering low
• MicroPower Operation:
155µA per Channel at 2.7V
• Power-On Reset to Zero-Scale
power operation and a flexible serial host interface.
Each on-chip precision output amplifier allows
rail-to-rail output swing to be achieved over the
supply range of 2.7V to 5.5V. The device supports a
• Power Supply: 2.7V to 5.5V
standard 3-wire serial interface capable of operating
• 16-Bit Monotonic Over Temperature
• Settling Time: 10µs to ±0.003% FSR
• Ultra-Low AC Crosstalk: –100dB Typ
• Low-Power Serial Interface With
with input data clock frequencies up to 30MHz for
VDD = 5V.
The DAC8552 requires an external reference voltage
to set the output range of each DAC channel. Also
incorporated into the device is a power-on reset
