The LTC1668IG#PBF is a 16-bit Digital to Analog Converter (DAC) manufactured by Analog Devices. It has a maximum sampling rate of 50Msps and consists of two independent digital-to-analog converters (DAC) that are capable of converting each sample to a voltage-output at rates up to 50Msps. Its output voltage range is low at 0.4V and high at 3.6V, making it ideal for many applications. It also features an unbuffered voltage reference, with a reference output range of 0.7V to 3.3V, adjustable with an internal resistor-divider network. On-chip features also include on-chip, low-cost filtering and digitally controlled filtering. The DAC has excellent dynamic performance, low distortion, and low noise. The LTC1668IG#PBF is suitable for use in various communications, communications systems, floating signal processing, and ultrasound applications.
