LTC2630AISC6-LZ12#TRPBF

Overview

The LTC2630AISC6-LZ12#TRPBF 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 guarantees monotonicity over the industrial temperature range of –40°C to 85°C. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a typical supply current of 180µA at 3V, and a power-down current of 1.8µA maximum. It utilizes a 3-wire SPI/Microwire compatible serial interface with clock rates up to 50MHz.

Feature Summary

• Integrated Precision Reference: Provides a stable 2.5V full-scale output with a low drift of 10ppm/°C.
• High Accuracy: Guaranteed monotonic operation with a maximum INL error of ±1 LSB for the A-grade device.
• Low Power Consumption: Operates with 180µA supply current at 3V and reduces to 1.8µA maximum in power-down mode.
• Compact Packaging: Housed in a tiny 6-lead SC70 package suitable for space-constrained designs.

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm that the 'I' grade corresponds to the industrial temperature range of –40°C to 85°C and the 'L' designation ensures the 2.5V internal reference. Ensure the 'Z' suffix is selected if a zero-scale power-on reset is required for system initialization.

Selection Notes

Select this component when a single-channel DAC with high DC accuracy and minimal board space is required. The A-grade specification is necessary for applications demanding a maximum INL of ±1 LSB. Choose the LZ variant over LM if the system requires the DAC output to initialize at zero scale upon power-up rather than mid-scale.

Part Context

This part belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family distinguishes itself by integrating a precision reference and rail-to-rail output buffer into a 6-lead SC70 package. Variants are categorized by temperature grade (C, I, H), reference voltage (L for 2.5V, H for 4.096V), and power-on reset behavior (M for mid-scale, Z for zero).
