Data acquisition plays a critical role in many digital applications, and Digital to Analog Converters (DAC) are critical in these systems. The LTC2645IMS-L10#TRPBF device from Linear Technology is a 12-bit single channel current output DAC which is suitable for many applications. It offers high precision and excellent settling time for rapid DC-to-DC conversion. This document provides an overview of the application fields and working principle of the LTC2645IMS-L10#TRPBF device.

Introduction

The LTC2645IMS-L10#TRPBF device is a 12-bit single channel current output DAC which provides high accuracy, excellent dc-dc conversion speed, and low power consumption. It offers a package size of 4 × 4 (mm) and is available in 8-pin flat non-leaded (FN) packages with an operating temperature range of –40 °C to +85 °C. It offers monotonic performance by using an innovative combination of static current sources and GaN-on-Si technology to guarantee precision and ultra-low-power performance. With an output current range of 0mA to 20mA, the device is ideally suited for applications such as motor control, alphanumeric displays, and sensor interfaces.

Application Fields

The LTC2645IMS-L10#TRPBF has a wide range of applications in the data acquisition field. As a current source DAC, it is ideal for driving LEDs, motors, and actuators. It can be used for current-to-voltage conversion, as well as for current-mode analog/PWM control. It also has high accuracy and excellent settling time, making it ideal for precision data-to-current conversion in applications such as data loggers, audio systems, and programmable logic controllers. In the field of power monitoring, the device provides solutions for precise monitoring of current and voltage levels in power supplies and motor controllers.

Working Principle

The LTC2645IMS-L10#TRPBF works by generating a precisely controlled current based on the 12-bit serial data input. The voltage across a sense resistor connected to the device determines the output current. The device uses static current sources in order to maintain a precise output current that is proportional to the 12-bit digital input. The output current is then converted to a voltage to be measured with an ADC or used to drive a load.

The device is powered from a single-supply voltage ranging from 4V to 16V, depending on the accuracy required for the selected sense resistor. The output current can be adjusted from 0mA to 20mA and the device is capable of driving up to 25mA of load current. The output voltage is determined by the sense resistor and can be in the range of 0V to 4V or 0V to 16V, depending on the single-supply voltage and the selected sense resistance.

The device can also be used to convert 12-bit serial data input to a setpoint voltage. This allows the device to be used in devices such as comparators, thermal sensors, and other analog applications. The output voltage is directly proportional to the digital data input and is not affected by variations in the supply voltage.
