LTC2624CGN-1#PBF

Overview

The LTC2624CGN-1#PBF 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 and built-in high-performance output buffers. The device operates on a single supply of 2.5V to 5.5V with a typical supply current of 1.3mA. It utilizes a simple SPI/Microwire compatible 3-wire serial interface supporting clock rates up to 50MHz. The -1 suffix indicates a power-on reset circuit that initializes outputs to midscale. Key electrical specifications include a settling time of 7µs, differential nonlinearity of ±0.5 LSB, and integral nonlinearity of ±0.9 LSB.

Feature Summary

• Quad 12-bit resolution with guaranteed monotonicity over temperature
• Power-on reset to midscale for the -1 variant
• Ultralow crosstalk between DACs (<5µV)
• High rail-to-rail output drive capability (±15mA)

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for end-of-life notices regarding production availability. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering.

Selection Notes

Select this model when a quad 12-bit DAC with independent reference inputs is required. The -1 suffix is necessary if mid-scale initialization upon power-up is desired. Compare against LTC2624 (zero-scale reset) or higher-resolution variants like LTC2614/2604 based on precision needs. Ensure the 2.5V to 5.5V supply range matches system constraints.

Part Context

This component belongs to the LTC2604/LTC2614/LTC2624 family of quad rail-to-rail DACs. The LTC2624 specifically offers 12-bit resolution, distinguishing it from the 14-bit LTC2614 and 16-bit LTC2604. All members share the same pinout and interface, allowing for design flexibility across resolution requirements within the same package footprint.
