LTC1650

Low Glitch 16-Bit

Voltage Output DAC

The LTC

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.

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 4

µs 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.
