The DAC7644E/1KG4 is a precision, quad-channel digital-to-analog converter (DAC) integrated circuit (IC) produced by Texas Instruments. This DAC offers high-resolution performance and excellent accuracy, making it suitable for a wide range of applications. Here are its key features:
1. Quad-Channel Configuration: The DAC7644E/1KG4 consists of four independent voltage output channels with simultaneous update capability, enabling it to provide precise analog output signals across different channels simultaneously.
2. High Resolution: It offers resolution up to 16 bits, allowing for extremely fine control of the analog output levels. This high resolution ensures accurate conversion of digital values to analog signals.
3. Low Integral Non-Linearity (INL): The INL specification determines the deviation of the output voltage from the ideal transfer function. The DAC7644E/1KG4 exhibits low INL, ensuring precise and predictable analog outputs across the complete input range.
4. Low Differential Non-Linearity (DNL): Similarly, DNL specifies the difference between actual and ideal step sizes of the DAC output. The DAC7644E/1KG4 maintains low DNL, contributing to its overall accuracy and linearity.
5. Low Glitch Impulse: Glitch impulses often introduce unexpected voltage spikes during the transition between consecutive digital input codes. This DAC minimizes glitch impulse, preventing unwanted signal artifacts and ensuring smooth transitions
