LTC2630ACSC6-LM12#TRMPBF

Overview

The LTC2630ACSC6-LM12#TRMPBF is a single-channel, 12-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 within a supply voltage range of 2.7V to 5.5V. The device incorporates a rail-to-rail output buffer and is guaranteed monotonic over the operating temperature range. It utilizes a simple SPI/MICROWIRE compatible 3-wire 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 typical supply current of 180µA at 3V, and power-down current as low as 1.8µA. The component is housed in a compact 6-lead SC70 package.

Feature Summary

• Integrated Precision Reference: Provides a stable 2.5V full-scale output with a temperature coefficient of 10ppm/°C.
• High Accuracy: A-grade specification guarantees a maximum Integral Nonlinearity (INL) error of ±1 LSB across the full temperature range.
• Rail-to-Rail Output: Features a rail-to-rail output buffer capable of driving capacitive loads up to 500pF while maintaining stability.
• Low Power Consumption: Operates with a typical supply current of 180µA at 3V and supports power-down mode with maximum current of 1.8µA.

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Automatic Test Equipment
• Portable Equipment
• Automotive

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel packaging quantity, distinct from the standard 2,500-piece reel. Confirm that the 'A' grade designation ensures the tighter ±1 LSB INL specification compared to standard grades. Ensure the C temperature grade (0°C to 70°C) aligns with the application's thermal requirements before procurement.

Selection Notes

Select this part when a single-channel DAC with high accuracy (±1 LSB INL) and a compact SC70 footprint is required. The LM suffix indicates a mid-scale power-on reset, which is suitable if downstream circuits can tolerate a non-zero initial output. For applications requiring zero-scale initialization, consider the LZ suffix variant. Ensure the system supply voltage falls within the 2.7V to 5.5V range for proper operation of the internal 2.5V reference.

Part Context

This component belongs to the LTC2630 family of single 12-/10-/8-bit rail-to-rail DACs with integrated references. The ACSC6-LM12#TRMPBF specifically denotes the Commercial temperature grade (C), 12-bit resolution (12), Mid-scale power-on reset (M), and 2.5V full-scale output (L). It shares the same core architecture and pinout as other variants in the series, differing primarily in accuracy grade, temperature range, and initialization behavior.

Replacement Considerations

Direct replacements within the same family include the LTC2630ACSC6-HM12#TRMPBF (4.096V full-scale) or LTC2630ACSC6-LZ12#TRMPBF (Zero-scale reset). Cross-family replacements may require interface and voltage level verification.
