LTC2606CDD-1#PBF

Digital To Analog Converters Overview

The LTC2606CDD-1#PBF is a single-channel, 16-bit rail-to-rail voltage output digital-to-analog converter (DAC) from Analog Devices. It operates on a 2.7V to 5.5V supply and features a buffered analog output capable of sourcing or sinking at least 15mA. The device communicates via a 2-wire I2C compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. A key characteristic of the '-1' suffix variant is its power-on reset behavior, which initializes the DAC output to mid-scale rather than zero scale. It is housed in a compact 3mm × 3mm 10-lead DFN package.

Digital To Analog Converters Feature Summary

• 16-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 -1 variants
• Rail-to-rail output drive with ±15mA minimum current capability

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix '#PBF' indicates lead-free finish and tube packaging. Confirm the '-1' designation matches the required mid-scale power-on reset state. Check RoHS compliance status as indicated in official documentation. Ensure the C-grade temperature range (0°C to 70°C) aligns with system requirements.

Digital To Analog Converters Selection Notes

Select this component when high board density is required for 16-bit precision. Choose the '-1' variant if mid-scale initialization upon power-up is necessary for downstream circuit safety. Ensure the I2C bus supports the required clock speed and that external pull-ups are provided for SDA and SCL lines.

Digital To Analog Converters Part Context

This part belongs to the LTC2606/LTC2616/LTC2626 family of rail-to-rail DACs. The 'C' grade denotes commercial temperature operation (0°C to 70°C). The 'D' indicates the DFN package type. The '1' suffix specifically configures the internal power-on reset logic to set outputs to mid-scale.

Digital To Analog Converters Replacement Considerations

LTC2606CDD#PBF: Identical electrical specifications but resets to zero scale on power-up instead of mid-scale.

Digital To Analog Converters FAQ

What is the default output state of the LTC2606CDD-1#PBF after power-up?

The LTC2606-1 variant resets the voltage output to mid-scale upon power-up. This differs from the standard LTC2606, which resets to zero scale.

How many selectable I2C addresses does the LTC2606 support?

The device supports 27 selectable slave addresses determined by the logic states (VCC, GND, or floating) of the CA0, CA1, and CA2 pins.

What is the maximum I2C clock frequency supported?

The device supports both standard mode (100kHz) and fast mode (400kHz) I2C interfaces.
