Direct Sensor Interface Technology (DSiT™)

DSiT enables designers to take an unconditioned, uncompensated, raw output signal from a sensor and interface it directly into a single-chip solution. DSiT incorporates all the elements necessary in an instrumentation system creating a balanced combination of features, allowing designers to create truly intelligent sensor systems.

DSiT is a unique capability integrated into the C8051F350 MCU and is ideal for many high-precision data acquisition and control applications including scientific instrumentation, medical equipment, process control, smart transmitters and weigh scales.

The ability to easily interface to small signals (hundreds of µV to tens of mV) is a requirement for many sensor designs. As technologies and applications continue to push the limits of detection, the system level challenges increase significantly. These challenges are further compounded when requirements of minimizing power dissipation providing intelligent processing and system cost reduction are further constrained.
