LTC1668IG#PBF

The LTC1668IG#PBF is a high-performance 16-bit differential current output Digital-to-Analog Converter (DAC) implemented on a state-of-the-art BiCMOS process with laser-trimmed, thin-film resistors. This DAC combines a novel current steering architecture with a high-performance process to produce exceptional AC and DC performance.

Operating from ±5V supplies, the LTC1668IG#PBF can be configured to provide full-scale output currents up to 10mA. The differential current outputs of the DAC allow for single-ended or true differential operation, providing flexibility in system design. The -1 to 1V output compliance of the LTC1668IG#PBF allows the outputs to be connected directly to external resistors to produce a differential output voltage without degrading the converter linearity. Alternatively, the outputs can be connected to the summing junction of a high-speed operational amplifier or to a transformer.

The LTC1668IG#PBF features TTL/CMOS inputs and a parallel data interface, making it easy to interface with various digital systems. It also offers high spectral purity with an SFDR of 87dB at 1MHz fOUT, ensuring accurate and noise-free analog output. With a settling time of 20ns (typical), the LTC1668IG#PBF is capable of handling high-speed data conversion tasks efficiently.

The LTC1668IG#PBF is packaged in a 28-pin SSOP (Shrink Small Outline Package), which is surface-mountable and suitable for high-density circuit boards. It operates over a wide temperature range of -40°C to 85°C, making it suitable for various industrial and automotive applications.

In summary, the LTC1668IG#PBF is a versatile and high-performance DAC that offers exceptional accuracy, speed, and flexibility. Its differential current output, high spectral purity, and compact packaging make it an ideal choice for a wide range of applications, including consumer electronics, communications and networking, wireless systems, sensing and instrumentation, and test and measurement equipment.
