LTC2629CGN-1#TRPBF

Overview

The LTC2629CGN-1#TRPBF is a quad 12-bit rail-to-rail voltage output digital-to-analog converter (DAC) in a 16-lead SSOP package. It features built-in high-performance output buffers and operates on a single supply of 2.7V to 5.5V. The device uses a 2-wire I²C compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. As a -1 variant, it incorporates a power-on reset circuit that sets outputs to mid-scale upon initialization. Key electrical specifications include ±0.5 LSB differential nonlinearity, ±1 LSB integral nonlinearity, and a maximum settling time of 7µs.

Feature Summary

• Quad 12-bit resolution with guaranteed monotonicity over temperature
• I²C interface with 27 selectable addresses via CA0/CA1/CA2 pins
• Power-on reset to mid-scale for the -1 suffix variant
• Rail-to-rail output drive capability (±15mA min at 5V)

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF against manufacturer documentation to confirm tape and reel packaging requirements. Confirm the -1 designation indicates the mid-scale power-on reset behavior required by the application design. Ensure the SSOP-16 footprint matches the PCB layout constraints.

Selection Notes

Select this component when four independent 12-bit channels are required in a compact SSOP-16 form factor. The -1 suffix is necessary if the system requires outputs to initialize at mid-scale rather than zero-scale during power-up. Verify that the I²C bus speed supports the 400kHz fast mode if higher data throughput is needed.

Part Context

This part belongs to the LTC2609/LTC2619/LTC2629 family of quad DACs. The LTC2629 specifically provides 12-bit resolution, whereas the LTC2619 offers 14 bits and the LTC2609 offers 16 bits. All members share the same pinout and interface protocol, allowing for potential pin-compatible upgrades or downgrades within the same package.

Replacement Considerations

LTC2629CGN-1#PBF: Same electrical specifications but supplied in tube packaging instead of tape and reel.
