The TLC2558IDW is a high-accuracy, low-cost, 10-bit A/D converter and 8-channel multiplexer integrated on a single chip. The TLC2558IDW is designed to be a direct substitute for the 8-channel TLC2554. The TLC2558IDW is a pin-compatible, direct upgrade in performance. It offers a single 5V supply, low power consumption and improved ac and dc performance over the TLC2554.

The TLC2558IDW is used for a variety of applications in data acquisition, instrumentation, and control. The ADC in the TLC2558IDW is capable of making accurate, repeatable, high-speed acquisitions of analog waveforms with a resolution of up to 10 bits. The 8-channel multiplexer integrated on the chip allows multiple inputs to be sampled with single-cycle conversion, providing improved system performance in a number of application areas. The improved accuracy and higher channel density of the TLC2558IDW over the TLC2554 allow applications covering a wide range of performance requirements. The TLC2558IDW also comes with an integrated low-cost process technology, thus making it ideal for cost-sensitive applications.

The TLC2558IDW operates with a variety of commonly used analog-to-digital conversion algorithms. It can be interfaced to host microcontrollers or custom control systems via an 8-bit control bus, allowing for simple, multiple-channel analog data acquisition. When used with a single-ended input, the TLC2558IDW ADC can achieve an unipolar conversion range of 0-5V with signal resolutions up to 8 bits. For data acquisition systems with bipolar inputs, the TLC2558IDW provides a true bipolar (differential) conversion range of +/- 5V with signal resolutions up to 10 bits.

The TLC2558IDW has several control pins that can be used to customize its operation. These include a Master Reset pin, a Load Data pin, a Start Conversion pin, and a Stop Conversion pin. The Master Reset pin clears all internal registers, including the A/D conversions results. The Load Data pin can be used to specify the conversion mode for the ADC. The Start Conversion and Stop Conversion pins can be used to manually trigger the start and stop of an A/D conversion. The ADC can also be put into a continuous conversion mode by setting the Start and Stop pins to their active "high" state.

The TLC2558IDW is a highly integrated, low power and low cost solution for a variety of data acquisition, instrumentation and control applications. Its high-accuracy, low-cost single-chip hardware makes it perfect for meeting the needs of modern systems. The use of widely accepted analog-to-digital conversion algorithms, along with its comprehensive control pins, provides the accuracy and control necessary for many control circuit applications.
