LTC2630HSC6-HM10#TRMPBF

Overview

The LTC2630HSC6-HM10#TRMPBF is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) housed in a 6-lead SC70 package. It features an integrated precision reference providing a full-scale output of 4.096V and operates from a 4.5V to 5.5V supply. The device includes a rail-to-rail output buffer guaranteed monotonic over temperature. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical parameters include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 4.4µs at 5V, and a supply current of 200µA. The part incorporates a power-on reset circuit configured to initialize the output to mid-scale.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C drift
• Rail-to-rail output buffer with guaranteed monotonicity
• Power-on reset to mid-scale option
• Low power consumption: 200µA operating current, 1.8µA max in power-down

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel quantity, distinct from the standard 2500-unit reel. Confirm the H-grade designation corresponds to the automotive temperature range of –40°C to 125°C. Ensure the HM suffix is correctly interpreted as the mid-scale power-on reset configuration for the 10-bit resolution variant within the SC70 package.

Selection Notes

Select this component when a compact single-channel DAC with high accuracy is required in space-constrained designs. The 10-bit resolution offers a balance between cost and performance. Choose the H-grade version for applications requiring operation up to 125°C. The mid-scale reset feature is critical if downstream circuits must avoid zero-voltage initialization states during power-up sequences.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family shares the same 6-lead SC70 footprint and core architecture but varies by internal reference voltage (2.5V or 4.096V), power-on reset behavior (zero or mid-scale), and temperature grade (Commercial, Industrial, or Automotive).

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630HSC6-LM10#TRMPBF (2.5V FS) or LTC2630HSC6-HZ10#TRMPBF (mid-scale vs zero-scale reset). Cross-family replacements like the LTC2634 require different packaging and pinouts.
