LTC2624IGN#TRPBF

Overview

The LTC2624IGN#TRPBF is a quad 12-bit rail-to-rail voltage output digital-to-analog converter (DAC) in a 16-lead narrow SSOP package. It operates on a single supply voltage ranging from 2.5V to 5.5V. Each of the four DAC channels features separate reference inputs and built-in high-performance output buffers capable of sourcing or sinking up to 15mA. The device utilizes a simple SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. Key electrical characteristics include a maximum differential nonlinearity (DNL) of ±0.5 LSB, integral nonlinearity (INL) of ±0.9 LSB, and an operating temperature range of –40°C to +85°C.

Feature Summary

• Quad 12-bit resolution with guaranteed monotonicity over temperature
• Separate reference inputs for each DAC channel
• Rail-to-rail output drive capability (±15mA)
• Ultralow crosstalk between DACs (<5μV)

Applications

• Mobile communications
• Process control and industrial automation
• Instrumentation
• Automatic test equipment

Procurement Notes

Verify that the #TRPBF suffix indicates tape and reel packaging. Confirm the IGN suffix corresponds to the industrial temperature range of –40°C to +85°C. Ensure the component is sourced from authorized distributors to guarantee authenticity and proper handling specifications for the SSOP package.

Selection Notes

Select the LTC2624 when 12-bit resolution is sufficient for the application, offering lower power consumption compared to higher-resolution variants like the LTC2604. Consider the separate reference input architecture if independent reference voltages are required per channel. Verify that the 16-lead SSOP package fits the board layout constraints and that the 3-wire serial interface matches the host controller's capabilities.

Part Context

The LTC2624 is part of the LTC2604/LTC2614/LTC2624 family of quad DACs. While pin-compatible, it differs from the LTC2604 (16-bit) and LTC2614 (14-bit) primarily in resolution and associated linearity specifications. All three share the same package, interface, and general functional architecture, allowing for design flexibility based on precision requirements.

Replacement Considerations

The LTC2624IGN#PBF is the tube-packaged equivalent of the same device. For replacement, ensure the substitute maintains the 12-bit resolution, SSOP-16 package, and industrial temperature rating. Direct pin-for-pin replacements within the same family include the LTC2604 and LTC2614, though their higher resolutions may require software adjustments.
