Data Acquisition - Digital Potentiometers

The MCP47DA1T-A1E/OT is a digital potentiometer from Microchip. It is a configurable, low-cost, 8-bit digital potentiometer with a non-volatile memory. Its low resistance and high accuracy make it suitable for applications where precision is a key factor.

In a digital potentiometer, there is a wiper whose position is determined by varying a digital code. This digital code is adjusted by two external pins: the digital input pin and the clock pin. This digital potentiometer can be used to control gains in amplifier circuits, modify the resistance of adjustable power supply circuits and to set the modulation level of digital oscillators. In addition, they can be used in combination with analog-to-digital converters (ADCs) in order to form an analog input channel to a microcontroller.

The MCP47DA1T-A1E/OT has two external pins that control the position of the on-chip wiper and the state of the non-volatile memory. Its operating voltage range is from 2.7V to 5.5V and a second reference voltage, typically 2.5V, can also be used. The low current consumption of the device makes it suitable for use in battery-operated systems.

The device is capable of both storing a value and driving an analog output in SPI or I2C communications. In addition, the device has an active low interrupt output, which can be used to alert a system of a change in the output value. The on-chip memory can store the output value even when there is no power. This means that the device can retain the same output value even if the power is cycled, saving the need to write values each time the power is cycled.

The MCP47DA1T-A1E/OT can be used in a wide range of different applications, such as audio systems, fuel injection systems and battery management systems. It can be used in applications where precision and flexibility are both needed. They are also useful in any application where a low-cost, flexible digital potentiometer is required.
