Analog-to-Digital converters (ADCs) are essential components in the electronic world. They are used to convert a continuous signal, such as an analog voltage, to a discrete digital number. The DC1805A-E Evaluation Board from Maxim Integrated is a 12-bit ADC that is designed to convert a voltage to a 12-bit digital code. The evaluation board is composed of several components, including an oscillator, a sample and hold circuit, an amplifier, a voltage reference and the ADC itself. The board also allows the user to measure input and output voltages. The board is designed to take input signals with frequencies between 0 and 5kHz.

The board features an onboard input buffer, allowing the user to attenuate the signal source for higher resolution. An on-board variable gain amplifier (VGA) allows the user to set the voltage gain for the desired dynamic range. Two multiplexers are included to route either the on-board signal source or the input signal to the ADC. Other features include an on-board programmable low pass filter, an output buffer, a PGA, an oscilloscope test point and an op amp.

The DC1805A-E board employs a successive approximation register (SAR) architecture to achieve its 12-bit resolution. SAR architectures are widely used because of their small size, low power consumption, and fast conversion speeds. The DC1805A-E board is capable of providing a single sample conversion rate of up to 20Msps. The evaluation board is also designed to check the maximum resolutions achievable with input signals of a specified frequency and amplitude.

The evaluation board is also equipped with an external timer to provide sample control and reset functions. The timer can be used to limit the sample rate or sequentially increase the sample rate for noise reduction. The timer also allows the user to control the conversion speed by programming the clock divider and dividing the sample rate of the ADC.

Maxim’s DC1805A-E evaluation board is a comprehensive, high performance ADC evaluation and development platform. The features of the board, including input buffering, gain selection, low-pass filtering, and multiplexer routing, makes it easy to develop applications with the ADC. The board also provides a wide input voltage range, high resolution and fast conversion speeds. Combined, these features make the DC1805A-E an ideal solution for ADC evaluation and development.
