The LTC2634CUD-LZ10#TRPBF is a digital to analog converter (DAC) manufactured by Linear Technology, a leader in the manufacture of high performance analog devices. Designed specifically for industrial and automotive applications, the device provides a comprehensive range of features to ensure reliable operation in both environment and temperature extremes. The device also has integrated power supply and interface protection, extended temperature operation, and Class B EMI/RFI immunity.

The LTC2634CUD-LZ10#TRPBF is a 16-bit, 10-Volt monolithic DAC with ±3LSB maximum DNL and a +VREF linearity of 8ppm/°C maximum. It features a wide operating power supply range of 4V to 16V, allowing for increased flexibility in system design. The device also features fast settling time and an SPI/MICROWIRE/DSP compatible 3-wire serial interface. It offers high resolution, low-power operation that is ideal for a variety of high-accuracy, low-system-cost designs.

The LTC2634CUD-LZ10#TRPBF is suitable for a variety of data acquisition applications, such as industrial process control, automotive system level control, instrumentation and test equipment. It is ideal for calibration and signal conditioning, signal generation, and voltage control and can also be used to provide accurate signal that requires precise control of multiple outputs. There is an optional 2-Wire Serial Interface, which allows programming and individual address decoding of up to 32 devices, enabling system designers to easily control each channel independently.

The LTC2634CUD-LZ10#TRPBF features a split architecture comprising the output amplifier, feedforward modulator, and output compensator. The device contains two low power comparators, two 16-bit latch registers, and two 8-bit reference DACs to produce unipolar and bipolar output Voltages. The application of this device is controlled by two control registers, two data latches and two data load/sync registers, which provide programmable latch enable/load control, output enable/disable, and reference scaling. The circuit operation is enabled by a user supplied logic signal which sets the oscillator, data latch enable and output enable lines.

The LTC2634CUD-LZ10#TRPBF’s asynchronous data-latching mechanism ensures that only the data that is clocked into the device will be used to update the analog output. This avoids any crosstalk from the data buses due to bus disturbances, making the device particularly suitable for applications that use multiple devices in a distributed system. Additionally, the zero-isolated outputs enable designers to maintain safety isolation in 3- wire systems and prevents thermal error caused by ground loops.

Furthermore, the device is specially designed to optimized for supply and temperature variation, providing excellent linearity and noise immunity. The device is power efficient, dissipating only 19mW of power in 10-Volt maximum output mode and 9mW in 5-Volt maximum output mode. The device is rated for an extended temperature range of -40C to 125C and the die is available in standard SO-20L and MSOP-16 packages. The device also has an integrated short-circuit protection and a circuit-diode-clamp feature, which prevents accidental overvoltages on the output.

To conclude, the LTC2634CUD-LZ10#TRPBF is a digital to analog converter designed for industrial and automotive applications. Its flexible design, extended temperature range, fast settling time, and integrated protection features, make it an ideal solution for digital-to-analog conversion in low-cost, high-accuracy distributed systems. It is a reliable and cost-effective solution for a wide range of data acquisition applications.
