LTC2627IDE#PBF

Overview

The LTC2627IDE#PBF is a dual 12-bit rail-to-rail voltage output digital-to-analog converter (DAC) from Analog Devices Inc. It operates on a single supply voltage ranging from 2.7V to 5.5V and features built-in high-performance output buffers. The device utilizes a 2-wire I2C compatible serial interface supporting standard mode (100kHz) and fast mode (400kHz). Key electrical specifications include a maximum differential nonlinearity (DNL) of ±0.5 LSB, integral nonlinearity (INL) of ±1.5 LSB, and a typical settling time of 7µs. It is housed in a compact 12-lead (4mm × 3mm) plastic DFN package with an exposed ground pad.

Feature Summary

• Dual-channel 12-bit resolution with guaranteed monotonicity over temperature
• I2C compatible serial interface with 27 selectable slave addresses via CA0/CA1/CA2 pins
• High rail-to-rail output drive capability with minimum ±15mA sourcing/sinking current
• Low power consumption: 260µA per DAC at 3V, reducing to 1µA max in power-down mode

Applications

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

Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free finish and tape/reel packaging availability. Confirm the 'IDE' designation corresponds to the industrial temperature range (-40°C to 85°C). Ensure the ordering information matches the required package type (12-Lead DFN) and check for any recent product change notices regarding material or assembly updates.

Selection Notes

Select the LTC2627IDE#PBF when dual-channel 12-bit precision is required in a minimal footprint. Compare against the LTC2617 (14-bit) or LTC2607 (16-bit) if higher resolution is necessary, noting they share pin compatibility. Consider the LTC2627CUFD#PBF if a QFN package is preferred over the DFN form factor. Ensure the application supports the 2.7V to 5.5V supply range and I2C bus capacitance limits.

Part Context

This component belongs to the LTC2607/LTC2617/LTC2627 family of small pin-compatible dual DACs. The 'IDE' suffix denotes the Industrial temperature grade (-40°C to 85°C), while the base model 'LTC2627' specifies the 12-bit resolution variant within this series. These devices are designed to replace larger octal DACs by providing dual channels in a significantly smaller package.

Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2617IDE#PBF (14-bit) and LTC2607IDE#PBF (16-bit). For lower resolution needs, the LTC1660 or LTC1665 families offer 10-bit and 8-bit options respectively, though they may differ in package or interface characteristics.
