Introduction of LTC2656BCFE-L16#TRPBF

The LTC2656BCFE-L16#TRPBF is a family of precision, low power, 16-bit, Serial Digital-to-Analog Converters (DACs) with integrated EEPROM memory. These DACs feature a compact 3 mm × 3 mm package, supply voltage range from 2.7V to 5.5V and a maximum output current of 8mA. The LTC2656BCFE-L16#TRPBF also has Pb-free (RoHS-compliant) packaging options to meet environmental requirements.

Application Field and Working Principle

Digital-to-Analog Converters (DACs) are electronic circuits that convert digital signals (such as those generated by CPUs and microcontrollers) into analog output signals. They are widely used in a variety of analog and digital electronics, as well as embedded systems, where output accuracy and flexibility are key factors.The LTC2656BCFE-L16#TRPBF is a Digital-to-Analog converter designed for a wide range of applications, such as LCD panel calibration, optical and audio systems, computer peripherals, automotive, and medical systems. Its integrated EEPROM memory allows for non-volatile storage of settings, and its low power operation allows it to run efficiently and reliably.The working principle of the DAC is based on the fact that digital signals are representations of voltage, current, or temperature values. Digital-to-analog conversion takes place when the values encoded in the digital signals are applied to a DAC\'s analog circuitry in order to produce an analog output voltage. The analog output voltage is proportional to the values encoded in the digital signals.In the LTC2656BCFE-L16#TRPBF, this conversion process begins with an 8 bit-to-16 bit parallel interface that converts the digital inputs into a serial bitstream. The serial bitstream is then sent to a voltage-mode successive approximation register (SAR) which converts the bitstream into an analog output voltage.The analog output voltage range for the LTC2656BCFE-L16#TRPBF is 0V to 4.096V with a 16-bit resolution. The output accuracy is +/- 2 LSB with an integrated temperature coefficient of less than 1 ppm/°C. The LTC2656BCFE-L16#TRPBF is designed for operation in temperatures from -40°C to 125°C and its power supply range can be set from 2.7V to 5.5V.Finally, the digital programming of the LTC2656BCFE-L16#TRPBF provides flexibility to adjust the reference voltage of the digital-to-analog conversion system, allowing users to customize their DACs to suit their own specific applications.

Conclusion

The LTC2656BCFE-L16#TRPBF is a family of low power, high precision, 16-bit Serial Digital-to-Analog Converters with integrated EEPROM memory. These DACs offer excellent accuracy and flexibility, allowing for custom applications. They are a suitable choice for a wide range of industrial applications, including LCD panel calibration, optical and audio systems, computer peripherals, automotive, and medical systems.
