To bridge the gap between digital-to-analog conversion and use, the LTC2637HMS-HMX10#PBF offers an ideal solution. This device features an integrated, low-drift reference, very low noise, and offers high linearity accurate to ±2 LSB.

Application Field

The LTC2637HMS-HMX10#PBFis useful in a variety of applications including instrument setup, sensor setup, data communication, and calibration of sensors used in military, aerospace, automotive and industrial applications. It is a single, 10-bit DAC with a 4mA to 20mA current output range and has a voltage output range of 0mV to 7.2V. The LTC2637HMS-HMX10#PBF is also suitable for applications in process control, machine or factory automation, or for general analog conversion.

Working Principle

The LTC2637HMS-HMX10#PBF is a digital-to-analog converter that can take a digital input and translate it into an analog output. The digital input can be from a serial peripheral interface (SPI) interface from a microcontroller, or it can come from an analog-to-digital converter (ADC). The voltage input is used to program the DAC. The digital output can be in different ranges, depending on your application. For example, the voltage range could be 0V to 7.2V, or the current range can be 4mA to 20mA.

When the LTC2637HMS-HMX10#PBF is used with an ADC, the analog inputs are converted to digital data and sent to the DAC. The DAC then uses the digital data to generate an analog voltage or current, depending on the application. The voltage output can then be further amplified if necessary. Additionally, the 10-bit resolution of the DAC ensures that it can produce very precise voltages or currents.

The LTC2637HMS-HMX10#PBF includes an integrated, low-drift reference. This reference is used to maintain the accuracy of the output over a wide range of temperatures. Additionally, the device features very low noise and high linearity, which is accurate to ±2LSB. It also features a power-on reset which sets the DAC output to midscale when power is applied.

The LTC2637HMS-HMX10#PBF offers up to 400kHz of SPI communication and is easy to use. It is available in an 8-pin SOIC and 8-pin TSSOP packages, making it ideal for precision applications such as 4mA to 20mA current loop applications. This device offers both high performance and high speed, making it suitable for a variety of different applications, including precision, 4mA to 20mA current loop applications.
