Data Acquisition - Digital to Analog Converters (DAC)A digital to analog converter (DAC) is a device that converts digital information into analog information. The LTC2654CUF-L12#TRPBF is a flexible, single-channel, 10-bit DAC. The device operates from a 2.7V to 5.5V supply range and supports rail-to-rail output, providing a full scale range of 0V to 3.2V. It features a maximum settling time of 25ns and a guaranteed accuracy of 0.5LSB max INL over temperature. The LTC2654CUF-L12#TRPBF DAC is ideal for applications with limited space or power requirements, such as 1- or 2-cell battery powered applications. It also has high accuracy (0.5LSB max INL & 0.75LSB max DNL), fast settling (<25ns), and wide operating temperature range (-40°C to 125°C). The device supports both 3-wire or 4-wire SPI interface and can operate in either hardware or software mode. When taking advantage of hardware-mode operation, the device can be updated as fast as 500Ksps. Additionally, the device supports a wide range of control voltages, allowing the user to select the range most suitable for their application.The LTC2654CUF-L12#TRPBF DAC offers three different modes of output buffering – True Rail-to-Rail (TR), Split Rail-to-Rail (SR) and High Bandwidth (HB). This allows the user to optimise the output stage for their specific application needs. TR mode offers the highest accuracy and allows for up to 600kHz small-signal bandwidth and low output offset voltage. SR mode allows for improved power supply noise rejection and higher small-signal bandwidth. HB mode offers the highest large-signal bandwidth and an adjustable gain of 1 to 5V/V.The LTC2654CUF-L12#TRPBF DAC is well suited for applications such as process and system monitoring, automotive, medical and industrial control, and audio and motion control systems. Its small size and low power (1.8mA) make it ideal for portable and low-power devices. It supports a wide range of operating temperature and is guaranteed to operate over temperature fluctuations between -40°C to 125°C. In summary, the LTC2654CUF-L12#TRPBF DAC is an ideal choice for applications requiring a single-channel DAC with a low current and fast settling time. It offers high accuracy and wide operating temperature range with three output buffering modes and is suitable for 1- or 2-cell battery powered applications. With its small size and low power, the LTC2654CUF-L12#TRPBF DAC is ideal for applications such as process and system monitoring, automotive, medical and industrial control, and audio and motion control systems.
