DAC101C085CIMMX/NOPB – TEXAS INSTRUMENTS

The DAC101C085CIMMX/NOPB is a 10-bit, current-output digital-to-analog converter (DAC) from Texas Instruments, packaged in a 8-pin SOIC (small outline integrated circuit) with a no-lead (NOPB) finish. It operates from a single 5V supply and features a maximum output current of 1mA. The device utilizes a R-2R ladder architecture, providing inherent linearity and monotonicity over its specified operating temperature range of -40°C to +85°C. Its output current is directly proportional to the digital input code, offering simple interfacing with microcontrollers and other digital systems. Unlike voltage-output DACs, the DAC101C085CIMMX/NOPB’s current output minimizes loading effects on the source, simplifying circuit design and improving accuracy in applications with varying loads._x000D_

Its low power consumption, typically under 20mW, makes it suitable for battery-powered applications. Common use cases include driving LED current sinks, precision current sources in instrumentation, and generating analog signals for control systems requiring high resolution and linearity within a limited voltage range. The absence of a voltage reference pin simplifies the bill of materials and reduces design complexity. The CIMMX suffix indicates a specific quality grade and testing procedure ensuring high reliability for critical applications. Engineers should consider this part when precision current generation is paramount, and a compact, low-power solution is needed.
