Description

LTC1458LCG - Precision Quad 12-Bit Voltage Output DAC

The LTC1458LCG is a high-performance, quad 12-bit digital-to-analog converter (DAC) designed by Linear Technology, now part of Analog Devices, to meet the demanding requirements of precision voltage control applications. Packaged in a compact 20-lead SSOP (Shrink Small Outline Package), this device offers a combination of features that make it an ideal choice for process control, automated test equipment, and digital calibration systems.

Key Features:

  • High Precision: The LTC1458LCG provides 12-bit resolution, ensuring fine granularity and precise control over the analog output voltage. This level of precision is essential for applications that require accurate signal generation or modulation.
  • Quad DAC Channels: With four independent DAC channels, this device allows for the simultaneous output of four different voltage levels, making it versatile for multi-channel applications.
  • Low Power Consumption: Designed with power efficiency in mind, the LTC1458LCG operates with a low supply current, which is crucial for battery-powered or energy-sensitive systems.
  • Flexible Voltage Outputs: The output voltage range is determined by the external reference voltage, providing flexibility in setting the desired output range for various applications.
  • Software-Selectable Shutdown: The device features a software-selectable shutdown mode that reduces power consumption when the DAC is not in use, further enhancing its suitability for power-conscious designs.

Applications:

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

The LTC1458LCG is engineered to interface seamlessly with microprocessors or digital signal processors, accepting 12-bit parallel input data to set the voltage output levels. The device's monolithic design and internal buffering ensure stable and reliable performance across a wide range of operating conditions. Moreover, the LTC1458LCG is characterized for operation from -40°C to 85°C, accommodating a broad spectrum of temperature environments.

For designers and engineers looking for a dependable and precise voltage output DAC, the LTC1458LCG from Linear Technology stands out as a robust solution that combines functionality and performance in a small form factor.
