Introduction

The LTC2755CUP-14#TRPBF is a 14-bit digital-to-analog converter (DAC) integrated circuit owned by Linear Technology Corporation. It converts digital numbers into corresponding analog voltage or current signal outputs. This voltage or current output signals can be applied to various analog electrical instruments, such as heaters, motors, sensors, and so on. The product also supports precision voltage and current output.

Application Field

The LTC2755CUP-14#TRPBF can be used in many different application fields. It can be used in a wide range of data acquisition systems. Its precision voltage and current output make it well-suited for applications such as digital-to-analog amplifiers, current sources, Wheatstone bridges, and industrial process control systems. It can also be used in applications like frequency synthesizers, instrumentation systems, and motor control. Moreover, the product can be used in medical imaging systems and robotics.

Working Principle

The LTC2755CUP-14#TRPBF is a 14-bit DAC that accepts digital-input commands to produce analog voltage or current outputs. The digital command is provided in a two-wire serial interface. The device supports a wide range of command word sizes: 8 bits, 10 bits, 12 bits, and 16 bits. The device can operate over a supply voltage range of 2.7V to 5.5V.

The device has several features, such as a power-down mode, a shut-down mode, and an output unipolar or bipolar voltage reference range. The power-down mode reduces power consumption by reducing the supply current. The shut-down mode shuts down the device and reduces power consumption to less than 2µA. The output voltage reference range can be selected for either 0V to 5V (unipolar) or -2.5V to +2.5V (bipolar) operation.

The product features low nonlinearity, low temperature coefficient, and low gain and offset errors, providing accurate and reliable output over the entire temperature range. In addition, the product includes internal logic to ensure over-temperature protection, over-voltage protection, short-circuit protection, and power-on reset.

The LTC2755CUP-14#TRPBF is a versatile DAC and provides a precision voltage or current output for many different applications. Its low nonlinearity, low temperature coefficient, and low gain and offset errors ensure accurate and reliable output and make it suitable for use in data acquisition and instrumentation systems, motor control, and industrial process control applications.
