LTC2630CSC6-LM12

Overview

The LTC2630CSC6-LM12 is a single-channel, 12-bit voltage-output digital-to-analog converter (DAC) housed in a 6-lead SC70 package. It features an integrated precision reference providing a 2.5V full-scale output and operates on a single 2.7V to 5.5V supply. The device includes a rail-to-rail output buffer, double-buffered data latches, and a power-on reset circuit configured to initialize the output to mid-scale. It communicates via a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical specifications include a maximum integral nonlinearity (INL) of ±1 LSB for the A-grade variant, a typical settling time of 4.4µs at 3V, and low power consumption of 180µA at 3V.

Feature Summary

• 12-bit resolution with ±1 LSB maximum INL (A-grade) and guaranteed monotonicity over temperature.
• Integrated 2.5V precision reference with 10ppm/°C drift; supports supply-as-reference mode.
• Power-on reset defaults to mid-scale output (suffix 'M').
• Low power operation: 180µA typical current at 3V; power-down mode reduces current to 1.8µA maximum.

Applications

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

Procurement Notes

Verify the specific suffix '#TRMPBF' indicates a 500-piece tape and reel packaging option. Confirm the temperature grade corresponds to the Commercial range (0°C to 70°C) as defined by the 'C' designation in the part number structure. Ensure the ordering information matches the required lead finish and RoHS compliance status specified in the manufacturer's current documentation.

Selection Notes

Select this component when a compact 6-lead SC70 footprint is required for space-constrained designs. Choose the 'LM' suffix if a mid-scale power-on reset state is necessary for system initialization safety. The 'L' series is suitable for applications requiring a 2.5V full-scale range with a supply voltage as low as 2.7V. For higher accuracy requirements, verify the need for the 'A' grade which guarantees tighter linearity specifications compared to standard grades.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family distinguishes between 'L' variants (2.5V FS, 2.7V–5.5V supply) and 'H' variants (4.096V FS, 4.5V–5.5V supply). The 'SC6' denotes the 6-lead SC70 plastic package. Other suffixes include 'Z' for zero-scale power-on reset and temperature grades 'I' (-40°C to 85°C) and 'H' (-40°C to 125°C).

Replacement Considerations
