LTC2630ISC6-LM10#TRMPBF

Overview

The LTC2630ISC6-LM10#TRMPBF is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a full-scale output of 2.5V and operates on a single 2.7V to 5.5V supply. The device includes a rail-to-rail output buffer and guarantees monotonicity over the operating temperature range. Key electrical parameters include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 3.9µs at 3V, and a typical supply current of 180µA. It utilizes a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz and is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated 10ppm/°C precision reference with 2.5V full-scale output
• Rail-to-rail output buffer guaranteed monotonic over temperature
• Power-on reset option to mid-scale for consistent initialization
• Low power operation: 180µA typical supply current, 1.8µA max in power-down

Applications

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

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 'I' grade corresponds to the industrial temperature range of –40°C to 85°C. Ensure the 'LM' designation matches the required mid-scale power-on reset behavior and 2.5V internal reference configuration for the design.

Selection Notes

Select this component when a single-channel DAC with high accuracy in a minimal footprint is required. The 10-bit resolution offers a balance between cost and performance. Choose the LM variant if a mid-scale output upon power-up is necessary for system safety or initialization. Verify that the 2.5V full-scale range meets the downstream circuit requirements, as the H-grade variants provide 4.096V.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 12-, 10-, and 8-bit resolutions. The family shares the same 6-lead SC70 package and core architecture but differs in accuracy grades (A vs. standard), full-scale voltages (L vs. H), and power-on reset states (M vs. Z). The ISC6 designation specifies the Industrial temperature grade and SC70 package type.

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2630ISC6-HM10#TRMPBF (4.096V FS) or LTC2630ISC6-LZ10#TRMPBF (Zero-scale reset). Cross-family replacements like the LTC2635 require I2C interface adaptation.
