Product Overview: LTC2635CUD-LMI12#PBF

The LTC2635CUD-LMI12#PBF is a high-precision, quad 12-bit voltage output digital-to-analog converter (DAC) with an integrated precision reference, produced by Analog Devices Inc. This component is part of a family of pin-compatible DACs with different resolution options, providing designers with flexibility in their applications. The LTC2635 series offers resolutions from 8 to 16 bits.

Encased in a compact, 16-lead QFN package, the LTC2635CUD-LMI12#PBF is designed to minimize the required board space, making it an ideal choice for space-constrained applications. The device operates over a wide supply voltage range of 2.7V to 5.5V, which allows for flexible integration into various system designs.

One of the key features of the LTC2635 is its integrated, high-accuracy reference, which delivers a stable and precise voltage for the DAC output. This internal reference has a low temperature coefficient, ensuring reliable performance over a wide temperature range. The DAC also provides a full-scale output voltage range of 0V to the reference voltage, giving users complete control over the output range.

Communication with the LTC2635CUD-LMI12#PBF is achieved through a 3-wire SPI-compatible serial interface, which supports high-speed data transfer and simplifies connection to microcontrollers or digital processors. The device includes a power-on reset circuit that ensures the DAC output powers up to zero volts and remains there until a valid write takes place. This feature is particularly useful in preventing unwanted transients during system startup.

The LTC2635 series is ideal for a wide range of applications, including process control, data acquisition systems, automatic tuning, and industrial automation. The LTC2635CUD-LMI12#PBF's combination of high precision, compact form factor, and ease of use makes it a top choice for engineers and designers looking to implement accurate analog output capabilities in their systems.
