LTC2624CGN-1#TRPBF

Overview

The LTC2624CGN-1#TRPBF is a quad 12-bit rail-to-rail voltage output digital-to-analog converter (DAC) in a 16-lead narrow SSOP package. It features separate reference inputs for each channel, built-in high-performance output buffers, and guaranteed monotonicity. The device operates on a single supply of 2.5V to 5.5V with a typical supply current of 1.3mA. It utilizes a 3-wire SPI/Microwire compatible serial interface supporting clock rates up to 50MHz. The -1 suffix indicates a power-on reset circuit that initializes outputs to midscale. Key electrical parameters include ±0.5 LSB DNL, ±0.9 LSB INL, and a settling time of 7µs.

Feature Summary

• Quad 12-bit resolution with rail-to-rail voltage outputs
• Power-on reset to midscale for the -1 variant
• Individual DAC power-down capability reducing current to 1µA max
• Ultralow crosstalk between channels (<5µV)

Applications

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

Procurement Notes

Verify the ordering suffix #TRPBF confirms tape and reel packaging. Confirm the -1 designation matches the required midscale power-on reset behavior. Check RoHS compliance status as specified in the manufacturer's documentation. Ensure the SSOP-16 package footprint aligns with the PCB design constraints.

Selection Notes

Select this component when four independent 12-bit voltage outputs are required in a compact form factor. Choose the -1 version if system initialization at midscale is preferred over zero scale upon power-up. Consider the 2.5V to 5.5V supply range and 50MHz serial interface speed for compatibility with the host controller.

Part Context

This part belongs to the LTC2604/LTC2614/LTC2624 family, differentiated by resolution: 16-bit, 14-bit, and 12-bit respectively. All variants share the same pinout and functional architecture. The CGN suffix denotes the commercial temperature range (0°C to 70°C), while IGN would indicate the industrial range (-40°C to 85°C).
