LTC2634-LZ12 Quad 12-Bit DAC

The LTC2634-LZ12 from Linear Technology is a family of quad 12-bit, voltage output digital-to-analog converters (DACs) with integrated precision reference. Designed to deliver high performance in a compact package, the LTC2634-LZ12 offers significant features for a range of applications including industrial control systems, automated test equipment, and high-end consumer products.

Key Features:

• Multiple Output Ranges: The device supports selectable output ranges of 0V to 2.5V, 0V to 5V, and ±2.5V (depending on the model), providing flexibility for various application requirements.
• Precision Integrated Reference: Comes with a 10ppm/°C max temperature coefficient reference, which reduces the need for external components and simplifies design.
• Low Power Operation: Its power consumption is optimized for battery-powered and portable applications, with a typical supply current of only 125μA per DAC.
• I²C Interface: Features an I²C compatible serial interface that supports standard (100kHz), fast (400kHz), and high speed (3.4MHz) modes for convenient communication with microcontrollers or processors.
• Double-Buffered Data Latches: Allows for simultaneous update of all DACs, which is particularly useful in control loop applications where timing is critical.
• Easy-to-Use: The LTC2634-LZ12 is designed for simplicity, requiring minimal external components and providing a straightforward interface for digital control.

Applications:

• Process Control and Industrial Automation
• Data Acquisition Systems
• Automated Test Equipment
• Digital Gain and Offset Adjustment
• Programmable Voltage and Current Sources

The LTC2634-LZ12 is housed in a 16-lead, 4mm × 3mm DFN or a 16-lead MSOP package, both of which are RoHS compliant. Its operating temperature range is from -40°C to +125°C, ensuring reliability across diverse environmental conditions. With its robust feature set and high precision, the LTC2634-LZ12 is an excellent choice for designers looking for a high-quality, quad-channel DAC solution.
