Working Principle:

At the core of the MCP6481T-E/OT amplifier is a high-performance integrated amplifier with a 5-bit digital input port for adjustable gain control ranging from 0.25 to 25. The device integrates a single-pole double-throw (SPDT) switch, which allows adjustable gain control simply by adjusting the voltage on the REF pin. There is also a parallel output in the chip to adjust the gain value easily, offering great flexibility for applications. The device also has a low offset voltage of 0.5 mV and low noise performance of 10 nV/Hz at 10 kHz. In addition, the amplifier has a low quiescent current of 4.8 mA, making it suitable for battery powered systems.

The device also features a rail-to-rail input range of ±100 mV and a wide gain linearity of 0.1%. In addition, it has a high output current capability of up to 300 mA. The device has a wide power supply range of 2.7 V to 36 V and is capable of operating at a maximum temperature of 105°C.

The device is built in a compact MSOP-8 package and is suitable for space-constrained applications. The package is lead-free, RoHS compliant and completely ESD-safe. This makes it an ideal choice for applications with stringent environmental standards and space restrictions.
