DAC082S085CIMM – TEXAS INSTRUMENTS

The DAC082S085CIMM is an 8-bit multiplying digital-to-analog converter (DAC) from Texas Instruments, packaged in a space-saving 20-pin TSSOP (Thin Shrink Small Outline Package). It operates from a ±15V supply voltage, featuring a typical output voltage range of ±10V, directly proportional to the digital input and reference voltage. The device utilizes an R-2R ladder architecture, resulting in inherent linearity and low output impedance (typically 50Ω). Its key specifications include a settling time under 1µs and a maximum total harmonic distortion (THD) of 0.1%. The DAC082S085CIMM includes an internal output amplifier, eliminating the need for external operational amplifiers in many applications._x000D_

This makes it ideal for applications requiring high-speed, accurate analog signal generation from a digital source, such as waveform synthesis in instrumentation, direct digital synthesis (DDS) systems, and precise control of analog actuators. Its multiplying functionality allows for easy gain adjustment via the reference voltage, offering flexibility in scaling the output signal. The low power consumption and small form factor are advantageous in portable and space-constrained designs. However, designers should note the relatively low resolution (8-bit) limits its precision compared to higher-bit DACs. Careful consideration of the input clock frequency and potential for glitches is also recommended.
