The TLV2541ID is a high-performance, low-power 8-bit Analog-to-Digital Converter (ADC) module intended for use in embedded systems in data acquisition applications. This device supports a wide variety of input sources, including thermocouples, RTDs, strain gauges, bridge transducers, and thermistors. TLV2541ID also supports single-ended inputs for both voltage and current, as well as differential input for current only. It has a wide operating temperature range of -40°C to +85°C and is capable of outputting data to an external microcontroller or host processor with an industry standard SPI interface.

The TLV2541ID ADC module is typically used in sensing applications with embedded systems. It can process analog signals from thermocouples, RTDs, strain gauges, bridge transducers, and thermistors and convert them into digital data. This data can then be interpreted by a host processor or microcontroller and used to adjust settings, start/stop processes, generate alarms, and more. The analog inputs of the device can range from 0mV – 3.3V and 0mA–3.3mA depending on the manufacturer’s version. The device includes a differential input that can handle up to 6.25mA (gaining 2.5mA resolution at 400Hz) and a single-ended input with a range of 0mV–3.3V or 0mA–3.3mA.

The TLV2541ID ADC module is an 8-bit resolution device with a maximum sample rate of 400Hz. The user can set the device to convert either single-ended or differential inputs depending on the application. The output data is in 8-bit codified values and can be outputted to a microcontroller or processor via Non-SPI, single byte mode via serial peripheral interface (SPI), or as a 16-bit value. The data can be outputted in either little-endian or big-endian format.

The TLV2541ID is a low-power device and has a typical power consumption of 45mW. Power can be supplied either through an external power supply, using external power pins, or through an 8-bit parallel port. The device can also be used in environments with a wide range of temperatures (–40°C to +85°C) and can withstand both static and dynamic shock and vibration.

The TLV2541ID provides a selectable digital filter for each channel, allowing for high precision results. This digital filter processes the acquired data in order to reduce various external signals such as power supply noise, static electricity, and EM interference. The digital filter can be set to ‘fast’, ‘med’, or ‘slow’ depending on the amount of filtering desired. Additionally, the TLV2541ID provides temperature and mechanical compensation. This allows for linearity within the device to be maintained in spite of temperature changes in the environment or mechanical impact on the device.

The TLV2541ID Analog-to-Digital Converter is an ideal choice for embedded systems in data acquisition applications. Its combination of low power consumption, low cost, wide temperature range, and shock and vibration resistance make it well-suited for many embedded systems. The device offers robust filtering and compensation to ensure consistent, accurate readings, and its 8-bit, 400Hz sample rate allows for quick and efficient data acquisition. Additionally, the device’s SPI interface makes for easy data transfer to external microcontroller or processor units.
