Data Acquisition - Analog Front End (AFE) is a key element in many data-driven systems, and Microchip’s MCP3901A0-E/SS is one of the most important components for such systems. This device includes four channels of 24-bit resolution, making it ideal for applications requiring high-resolution data acquisition. The MCP3901A0-E/SS includes a full-featured analog input subsystem, including a programmable gain amplifier, delta-sigma analog-to-digital converter (ADC), and an analog multiplexer with auto-zeroing capabilities.

The MCP 3901A0-E/SS provides a low power, high-performance, high-resolution ADC solution, combining robust signal-to-noise and dynamic range performance, with ease of use. The MCP 3901A0-E/SS offers single-ended analog input, and the three available input gains (1x, 2x, and 4x) let you tune the gain to the signal, providing superior noise reduction performance. This makes the MCP 3901A0-E/SS an ideal solution for power monitoring, harsh environment measuring, and many industrial-applications.

The programmable gain amplifier (PGA) in the MCP 3901A0-E/SS features a programmable gain of 1 to 1024, allowing it to amplify signals from a wide variety of sensors. The PGA is also fully programmable, allowing you to adjust the gain to meet the specifications required by your application. Additionally, the PGA features a programmable low pass filter which can be set to reduce noise and eliminate out-of-band signals.

The analog-to-digital converter (ADC) in the MCP3901A0-E/SS is a delta-sigma converter, meaning it uses a single-bit architecture to achieve higher resolution than standard analog-to-digital converters. This ADC has an effective resolution of up to 24-bits, and operates in either single-ended or differential input configurations. Additionally, the ADC contains a low-noise programmable gain amplifier which can be programmed to offer a wide dynamic range and low noise performance.

The MCP3901A0-E/SS includes an analog multiplexer with auto-zeroing capabilities, and can be used to switch between four different inputs. This multiplexer contains two analog inputs and two digital outputs, which can be used to switch between a single-ended input and a differential input. Additionally, the MCP3901A0-E/SS can be synchronized to external events, allowing multiple channels to be sampled simultaneously.

The MCP3901A0-E/SS also utilizes an internal clock generator, allowing the device to operate at high speed, even in extreme temperature environments. This makes the MCP3901A0-E/SS an ideal solution for power monitoring, harsh environment measuring, and many industrial-applications, as it is capable of high-speed ADC performance for full-field acquisition. For example, the MCP3901A0-E/SS provides the highest resolution and sample rate of any 24-bit delta-sigma ADC, making it an ideal choice for high-resolution analog signal acquisition applications such as data logging.

The MCP3901A0-E/SS is an excellent solution for many applications requiring high-resolution data acquisition. Its full-featured analog input subsystem, including a programmable gain amplifier, delta-sigma ADC, and an analog multiplexer with auto-zeroing capabilities, make it an ideal fit for many industrial, power monitoring and harsh environment measuring applications. Additionally, its high-speed internal clock generator allows it to achieve high-speed ADC performance, even in extreme temperature environments.
