Digital to Analog Converters (DAC) are essential for a variety of data acquisition processes. The LTC 1458LCSW#PBF is a highly efficient and reliable converter that has the capability to generate high precision analog outputs from a digital input. This device is primarily used in industrial, automotive, consumer and medical applications.

The LTC 1458LCSW#PBF is a 8-bit digital to analog converter that can convert an 8-bit digital code to a 10-bit DAC output. The device operates with a 2.5x voltage reference, providing a 0.2%, 8-bit accurate output current. The converter is ideal for space-constrained and low-power applications, consuming only 7.5mW of power while operating at full speed. The device is also very robust in terms of temperature and power supply range, with a wide operating temperature range of -55C to 125C, and a supply voltage range of 2.7V to 5.5V.

The device uses a two-step process to convert the digital code to an analog output. First, the digital code is converted to a voltage using a resistor string. Then, the voltage is converted to an output current using a precision Current Mode Architecture (CMA). This architecture reduces the amount of noise generated during the conversion process and improves the device\'s linearity and accuracy.

The LTC 1458LCSW#PBF has several key features that make it an ideal choice for various digital to analog conversion applications. It has an integrated high-voltage output buffer, providing a 10V digital-to-analog output. This allows for use in higher voltage applications that require light weight, low power and thermal dissipation.

Additionally, the device offers two separate power supplies, one for the voltage reference and one for the rest of the device circuitry, which makes it easier to configure for power-sensitive applications. The device also includes calibration options, including offset and gain calibration, giving users the ability to adjust performance parameters to accommodate any variation in the application environment.

The LTC 1458LCSW#PBF is capable of providing a wide range of analog output levels with excellent accuracy. This makes it ideal for applications such as motor control, robotics, audio and video processing, as well as any other digital-to-analog conversion applications that require precise, reliable and high performance operation.
