LTC2630CSC6-HM12#TRPBF

Overview

The LTC2630CSC6-HM12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference yielding a 4.096V full-scale output and operates on a 4.5V to 5.5V supply. The device features a rail-to-rail output buffer, SPI/MICROWIRE compatible 3-wire serial interface, and double-buffered data latches. Key electrical parameters include a maximum integral nonlinearity of ±2 LSB, settling time of 4.8µs at 5V, and power consumption of 200µA. It supports power-down modes with current draw as low as 1.8µA and includes power-on reset options.

Feature Summary

• 12-bit resolution with integrated 4.096V precision reference
• SPI/MICROWIRE compatible 3-wire serial interface operating up to 50MHz
• Rail-to-rail output buffer with guaranteed monotonicity
• Power-on reset to mid-scale or zero-scale options

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive systems

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a 2,500-piece tape and reel packaging configuration. Confirm the temperature grade 'C' corresponds to the commercial range of 0°C to 70°C. Ensure the 'H' designation for full-scale voltage matches the required 4.5V to 5.5V supply operation constraints for the design.

Selection Notes

Select this part when a compact SC70 package is required alongside high DC accuracy. The HM suffix specifies a mid-scale power-on reset state; choose HZ if a zero-scale initialization is preferred. Verify that the system supply voltage remains within the 4.5V to 5.5V range, as lower voltages are not supported by the H-grade internal reference configuration.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family distinguishes between L-grade parts (2.5V FS, 2.7V-5.5V supply) and H-grade parts (4.096V FS, 4.5V-5.5V supply). The CSC6 package denotes the 6-lead SC70 form factor used for space-constrained designs.
