LTC2629CGN#PBF

Overview

The LTC2629CGN#PBF is a quad 12-bit rail-to-rail voltage output digital-to-analog converter (DAC) from Analog Devices. It operates on a single supply voltage ranging from 2.7V to 5.5V and features built-in high-performance output buffers guaranteed monotonic over temperature. The device utilizes a 2-wire I²C compatible serial interface supporting standard mode (100kHz) and fast mode (400kHz). It incorporates a power-on reset circuit that holds outputs at zero-scale until a valid write and update occur. The component is housed in a 16-lead narrow SSOP package.

Feature Summary

• Quad 12-bit resolution with rail-to-rail voltage output
• I²C interface with 27 selectable addresses via CA0, CA1, CA2 pins
• Power-on reset to zero-scale for consistent initialization
• Individual channel power-down capability reducing current to 1µA max

Applications

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

Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free finish and tube packaging as per the ordering information table. Confirm the 'GN' designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure compatibility with the 16-lead plastic SSOP footprint during procurement planning.

Selection Notes

Select this model for applications requiring four independent 12-bit channels with I²C connectivity. Choose the CGN variant for commercial temperature environments (0°C to 70°C). If mid-scale power-on reset behavior is required instead of zero-scale, consider the -1 suffix variants such as LTC2629CGN-1#PBF.

Part Context

This part belongs to the LTC2609/LTC2619/LTC2629 family of pin-compatible quad DACs. While the LTC2609 offers 16-bit resolution and the LTC2619 provides 14-bit resolution, the LTC2629 specifically delivers 12-bit performance. All three share the same 16-lead SSOP package and electrical interface characteristics.

Replacement Considerations

LTC2629CGN-1#PBF: Identical specifications but resets to mid-scale upon power-up.
