LTC2630AHSC6-HZ12#TRPBF

Overview

The LTC2630AHSC6-HZ12#TRPBF is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference with a 4.096V full-scale output and a 10ppm/°C temperature coefficient. The device operates within a supply voltage range of 4.5V to 5.5V and features a rail-to-rail output buffer guaranteed monotonic over the –40°C to 125°C automotive temperature range. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB for the A-grade device, a settling time of 4.8µs at 5V, and a power-down current of 5µA maximum.

Feature Summary

• 12-bit resolution with ±1 LSB maximum INL error (A-Grade)
• Integrated 4.096V precision reference with 10ppm/°C drift
• Automotive temperature grade: –40°C to 125°C
• Rail-to-rail output buffer with 500pF capacitive load stability

Applications

• Automotive sensor signal conditioning
• Process control and industrial automation systems
• Portable battery-powered equipment requiring low power
• Automatic test equipment (ATE)

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a 2,500-piece tape and reel packaging format. Confirm that the H-grade designation matches the required –40°C to 125°C operating temperature range for the target application environment. Ensure the Z-suffix power-on reset configuration aligns with system initialization requirements.

Selection Notes

Select this part when a single-channel DAC with high accuracy (±1 LSB INL) and automotive reliability is required. The H-grade variant necessitates a minimum supply voltage of 4.5V to achieve the specified 4.096V full-scale output. Consider the 5µA power-down current if battery life is critical, noting that power-up delay may affect rapid update applications.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 6-lead SC70 packages. The family offers combinations of resolutions (8-, 10-, or 12-bit), full-scale voltages (2.5V or 4.096V), and temperature grades (C, I, or H). The A-grade designation specifically denotes enhanced linearity performance compared to standard C or I grades.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Cross-referencing should focus on pin-compatible devices with similar 12-bit resolution, 4.096V internal reference, and automotive temperature ratings.
