LTC1650
Low Glitch 16-Bit
Voltage Output DAC
DESCRIPTIO
The LTC®1650 is a deglitched rail-to-rail voltage output
16-bit digital-to-analog converter (DAC) available in a
16-pin narrow SO package. It has 16-bit monotonicity
over temperature and includes a rail-to-rail output buffer
amplifier and an easy to use three-wire cascadable serial
interface. The LTC1650 operates with dual ±5V supplies.
With REFLO = 0V and REFHI = VREF, the output will swing
from 0V to VREF in unipolar mode or ±VREF in bipolar
mode.
The LTC1650 has excellent accuracy over its full operating
temperature range along with very low power dissipation
of 50mW with dual ±5V supplies. This, along with the
small outline package, makes it the most flexible high
resolution digital-to-analog converter available today.
The LTC1650 has a fast settling time of 4µs to 16 bits and
a low midscale glitch of under 2nV-s. This makes the
LTC1650 ideal for waveform generation or other applica-
tions where output dynamic performance is important.
