LTC2625CGN#TRPBF

Overview

The LTC2625CGN#TRPBF is an octal 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 of 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). Key electrical specifications include a settling time of 7µs, ±0.5 LSB differential nonlinearity, and ±1 LSB integral nonlinearity. Supply current is 2.5mA at 5V, with individual channel power-down reducing consumption to 1µA maximum.

Feature Summary

• Octal 12-Bit Resolution: Eight independent DAC channels with 12-bit precision in a compact 16-lead SSOP package.
• I²C Interface: Supports standard (100kHz) and fast (400kHz) modes with 27 selectable addresses via CA0-CA2 pins.
• Rail-to-Rail Output: Buffered outputs drive loads up to ±15mA with ultralow crosstalk (<10µV).
• Power Management: Individual channel power-down reduces current to 1µA; power-on reset clears outputs to zero-scale.

Applications

• Mobile Communications
• Process Control and Industrial Automation
• Instrumentation
• Automatic Test Equipment

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the CGN suffix corresponds to the commercial temperature range of 0°C to 70°C. Ensure the order includes the specific lot traceability required by your manufacturing process. Cross-reference the datasheet revision against the supplier's documentation to guarantee parameter consistency.

Selection Notes

Select this component when eight buffered analog outputs are required in a space-constrained design. The 12-bit resolution offers a balance between cost and accuracy for general-purpose control loops. Choose the -1 variant if mid-scale power-on reset is preferred over zero-scale. Verify that the I²C bus capacitance does not exceed 400pF for reliable fast-mode operation.

Part Context

This part belongs to the LTC2605/LTC2615/LTC2625 family of pin-compatible octal DACs. The LTC2605 provides 16-bit resolution, the LTC2615 offers 14-bit resolution, and the LTC2625 delivers 12-bit resolution. All variants share identical pinouts and interfaces, allowing for easy upgrades or downgrades in board designs without layout changes.

Replacement Considerations

LTC2625IGN#TRPBF: Identical electrical performance but rated for industrial temperature range (-40°C to 85°C).
