Typical Application

Description

The LTC1650 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 = V_REF, the output will swing from 0V to V_REF in unipolar mode or ±V_REF 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 applications where output dynamic performance is important.
