LTC2626IDD#PBF

Overview

The LTC2626IDD#PBF is a single-channel, 12-bit rail-to-rail voltage output Digital-to-Analog Converter (DAC) manufactured by Analog Devices Inc. It operates within a supply voltage range 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 (100kHz) and fast (400kHz) modes, along with an asynchronous DAC update pin (LDAC). Packaged in a compact 3mm × 3mm 10-lead DFN format, it includes power-on reset circuitry that defaults outputs to zero scale upon initialization.

Feature Summary

• 12-bit resolution with guaranteed monotonicity over the operating temperature range
• Rail-to-rail voltage output with high drive capability (±15mA minimum)
• I2C compatible serial interface with 27 selectable addresses via CA0/CA1/CA2 pins
• Low power consumption: 270µA at 3V supply, down to 1µA maximum 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 tube packaging when sourcing. Confirm the IDD suffix corresponds to the –40°C to +85°C industrial temperature grade. Ensure the ordering information matches the required package type and thermal characteristics for the target application environment.

Selection Notes

Select the LTC2626IDD#PBF for applications requiring 12-bit precision in a minimal footprint. Compare against LTC2606 or LTC2616 variants if higher resolution (16-bit or 14-bit) is necessary, as they share pin compatibility. Consider the LTC2626-1 variant if mid-scale power-on reset behavior is preferred over the zero-scale default of the standard part.

Part Context

This component belongs to the LTC2606/LTC2616/LTC2626 family of single DACs. While sharing identical pinouts and interfaces, the family differentiates by resolution: 16-bit (LTC2606), 14-bit (LTC2616), and 12-bit (LTC2626). The 'IDD' designation specifies the industrial temperature range and plastic DFN packaging, distinguishing it from commercial grades or tape-and-reel options.

Replacement Considerations

Pin-compatible replacements within the same family include LTC2606IDD#PBF (16-bit) and LTC2616IDD#PBF (14-bit). For mid-scale power-on reset functionality, consider LTC2626IDD-1#PBF. Verify that any substitute maintains the required I2C address configuration and output drive specifications.
