LTC2630HSC6-HM10#TRPBF

Overview

The LTC2630HSC6-HM10#TRPBF is a single-channel, 10-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 within a 4.5V to 5.5V supply range. The device features a rail-to-rail output buffer, guaranteed monotonicity, and an SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. Key electrical parameters include a typical settling time of 4.4µs, a maximum integral nonlinearity (INL) of ±1 LSB, and a power-down current of 1.8µA maximum. It is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated 4.096V precision reference with 10ppm/°C temperature coefficient
• Rail-to-rail output buffer with guaranteed monotonicity over temperature
• Power-on reset to mid-scale for consistent system initialization
• Low power consumption: 200µA typical at 5V; 1.8µA max in power-down mode

Applications

• Mobile communications systems
• Process control and industrial automation
• Automatic test equipment
• Portable battery-powered equipment
• Automotive electronics

Procurement Notes

Verify the specific suffix #TRPBF indicates a 2,500-piece tape and reel packaging format. 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. Cross-reference the I-grade temperature rating if industrial operation outside the automotive range is required.

Selection Notes

Select this part when a 4.096V internal reference is preferred over an external one. Choose the HM variant if a mid-scale output is desired upon power-up rather than zero-scale. Verify that the 4.5V minimum supply voltage aligns with the system's power rails. Consider the SC70 package size constraints and the 50MHz serial interface speed requirements for the host microcontroller.

Part Context

This component belongs to the LTC2630 family, which offers 12-, 10-, and 8-bit resolutions in a 6-lead SC70 package. The 'H' grade denotes the extended temperature range suitable for automotive applications. The 'HM' designation specifies the mid-scale power-on reset behavior, distinguishing it from the 'HZ' zero-scale variant. All variants share the same pinout and core architecture.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users must verify compatibility with existing designs if considering alternative DACs.
