LTC2630HSC6-LM8#TRPBF

Overview

The Analog Devices LTC2630HSC6-LM8#TRPBF is a single-channel, 8-bit voltage-output digital-to-analog converter housed in a 6-lead SC70 package. It features an integrated precision reference providing a full-scale output of 2.5V with a temperature coefficient of 10ppm/°C. The device operates from a single supply ranging from 4.5V to 5.5V and includes a rail-to-rail output buffer guaranteed monotonic over temperature. Key electrical parameters include a maximum integral nonlinearity (INL) error of ±2 LSB, a typical settling time of 3.7µs at 5V, and a supply current of 180µA. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface for control.

Feature Summary

• Integrated 10ppm/°C precision reference yielding a 2.5V full-scale output
• Rail-to-rail output buffer with guaranteed monotonicity over temperature
• Power-on reset circuit configured to initialize outputs to mid-scale
• Low power consumption: 180µA operating current and 1.8µA maximum 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 ordering suffix #TRPBF indicates a 2,500-piece tape and reel packaging configuration. Confirm that the H-grade designation corresponds to the automotive temperature range of –40°C to +125°C. Ensure the LM suffix correctly specifies the mid-scale power-on reset behavior and the L suffix denotes the 2.5V internal reference voltage before finalizing procurement orders.

Selection Notes

Select this component when a compact 6-lead SC70 footprint is required for 8-bit resolution applications. Choose the H-grade variant if operation within the –40°C to +125°C automotive temperature range is necessary. The LM suffix is appropriate for systems requiring a mid-scale initialization upon power-up, whereas the LZ suffix would be selected for zero-scale initialization. Verify that the 4.5V to 5.5V supply requirement aligns with the system design.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 12-, 10-, and 8-bit resolutions. The family shares a common architecture featuring an integrated low-drift reference and a 3-wire serial interface. Variations within the family are distinguished by resolution codes (12, 10, 8), reference voltage options (L for 2.5V, H for 4.096V), and power-on reset states (M for mid-scale, Z for zero).

Replacement Considerations
