Linear Technology LTC1458CG Product Overview

The LTC1458CG is a high-performance, octal 12-bit voltage output digital-to-analog converter (DAC) produced by Linear Technology. Designed with precision and versatility in mind, this product offers an array of features that make it an excellent choice for demanding applications that require accurate analog output from digital signals.

Encased in a 16-lead SSOP package, the LTC1458CG integrates eight DACs in one compact unit, significantly reducing the space required on a printed circuit board and simplifying design. Each of the eight DACs can be independently programmed via a 3-wire serial interface, which allows for easy interfacing with microprocessors or digital systems and contributes to a reduction in the complexity of system design.

The LTC1458CG operates from a single 5V supply, providing an output voltage range that extends from 0V to reference voltage, which can be up to 5V. This feature enables the device to deliver a wide dynamic range, making it suitable for a broad spectrum of applications, including process control, data acquisition systems, and automated test equipment.

Key features of the LTC1458CG include:

• 12-bit resolution for each DAC, ensuring fine granularity and precise control over the analog output.
• Guaranteed monotonic performance over the full operating temperature range, which maintains signal integrity and accuracy.
• Low power consumption, a critical attribute for energy-sensitive applications.
• Double-buffered data latches, which allow for simultaneous update of all DACs.
• Software-selectable internal or external reference, giving designers flexibility in setting the output voltage range.

The LTC1458CG also boasts a robust design with built-in protection features. Its output amplifiers are short-circuit protected, and the device includes a power-on reset circuit that ensures the DAC outputs power up to zero volts and remain there until a valid write takes place.

With its combination of high precision, ease of use, and advanced features, the LTC1458CG from Linear Technology is an ideal solution for designers looking to integrate multiple DACs into their systems without compromising on performance or board space.
