The LMH3401IRMSR is a single-channel, high-resolution, wide-dynamic range analog-to-digital converter (ADC) with an integrated noise-canceling input stage and optional on-chip temperature compensation to a specific humidity range. Unique to the LMH3401IRMSR is its ability to monitor peak signals and accurately measure AC current, DC current, and AC and DC voltage signals.

This makes it ideal for instrumentation, linear amplifiers, and other applications (e.g., medical, industrial, and automotive) that require accurate, high-resolution measurements in a wide dynamic range, without the need to compensate for external noise sources.

LMH3401IRMSR Application Field and Working Principle

The LMH3401IRMSR is designed for use in instrumentation, linear amplifiers, and other applications that require accurate, high-resolution measurements with wide dynamic range and noise cancellation. The device operates on a single supply and achieves a Noise Factor of 0.0045% FSR (up to 12.8 Msps), making it suitable for sensor designs and diagnostics.

The LMH3401IRMSR has two channels to measure AC or DC signals as well as signals that simultaneously vary in both frequency and voltage (e.g., multi-phase power supply measurements). The device includes an on-chip power supply and adjustable overrange voltage modes. The on-chip power supply provides the necessary level-shifting and voltage reference for the device.

The LMH3401IRMSR also offers several features that simplify data collection, including integrated gain and offset control, internal filtering, and programmable input range selection. The device also has a built-in thermal compensation module that enables users to ensure consistent and accurate readings in humid environments. The device can be operated over a wide temperature range (-40°C to +125°C), and features ESD protection on all I/O pins.

The LMH3401IRMSR provides very low noise performance due to its integration of noise correction and cancellation components. The device has an open-loop measurement architecture that eliminates the need for external loop compensation circuitry. This architecture uses an on-chip, low-noise, noise-canceling input amplifier, which pre-amplifies the signal before it is digitized by the ADC.

The low-noise design of the LMH3401IRMSR makes it suitable for precision instrumentation. It has a wide dynamic range and high speed (e.g., 12-bit 500kHz measurements), making it ideal for applications that require accurate and fast measurements such as medical diagnostics and industrial monitoring. The device also features an adjustable integral nonlinearity (INL) of up to 0.1%, which enables it to achieve high accuracy measurements.

The device is powered by an on-chip reference and can be connected to an onboard JTAG interface for programming, which makes it an ideal choice for systems that require low power consumption. The LMH3401IRMSR can also be used with an external hardware trigger or GPIO to enable synchronization with other devices or systems.

In summary, the LMH3401IRMSR is a powerful ADC that is suitable for instrumentation, linear amplifiers, and other applications requiring accurate, high-resolution measurements with wide dynamic range and noise cancellation. The device has a wide range of features and capabilities, making it a great choice for applications that require low noise, high accuracy, and low power consumption.
