LTC2630ISC6-HZ10#TRPBF

Overview

The LTC2630ISC6-HZ10#TRPBF is a single-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision reference providing a full-scale output of 4.096V and operates within a supply voltage range of 4.5V to 5.5V. The device features a rail-to-rail output buffer, guaranteed monotonicity, and an SPI/MICROWIRE compatible 3-wire serial interface supporting clock rates up to 50MHz. It includes a power-on reset circuit configured to clear the output to zero scale upon initialization. The component is housed in a compact 6-lead SC70 package and supports industrial temperature operation from -40°C to +85°C.

Feature Summary

• 10-bit resolution with integrated 4.096V precision reference
• Rail-to-rail output buffer with guaranteed monotonicity
• Power-on reset to zero scale for consistent system initialization
• Industrial temperature grade (-40°C to +85°C) in 6-lead SC70 package

Applications

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

Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature grade and power-on reset configuration. Confirm the package type matches the design footprint requirements. Ensure the supply voltage constraints align with the system's power rails, as this variant requires a minimum of 4.5V. Check for lead-free compliance documentation if necessary for regulatory standards.

Selection Notes

Select this part when a 10-bit resolution is sufficient and a fixed 4.096V full-scale output is desired. The zero-scale power-on reset feature is critical for applications where downstream circuits must remain inactive or at ground potential during startup. Compare against the HM variant if mid-scale reset is preferred. Consider the H-grade temperature range if operation beyond 85°C is required.

Part Context

This component belongs to the LTC2630 family of single-channel DACs available in 8-, 10-, and 12-bit resolutions. The family distinguishes itself by integrating a high-accuracy reference into a tiny SC70 package. Variants are defined by their full-scale voltage (L for 2.5V, H for 4.096V), power-on reset behavior (Z for zero, M for mid-scale), and temperature grade (C, I, or H).
