• SPI-compatible serial interface with up to 50MHz clock
• Low power consumption: 0.35mA per DAC at 3V
• Power-on reset to zero-scale output
• Wide operating temperature range: -40°C to +85°C
• Available in 8-lead TSOT-23 package

Applications

• Portable instrumentation
• Process control and automation
• Data acquisition systems
• Digital gain and offset adjustment
• Battery-powered devices

Selection Guidance

The LTC2633 family offers multiple resolution options (8, 10, and 12-bit) and reference voltage choices. The -LI10 suffix indicates a 10-bit resolution with internal 2.5V reference. For applications requiring higher resolution, consider the LTC2633-LI12. For external reference operation, select the -H or -L variants without internal reference. Always verify the exact specifications in the datasheet before design-in.
