The EVAL-AD7605-4SDZ is a Multi-channel, Precision Analog-to-Digital Converter (ADC) Evaluation Board from Analog Devices. The board is populated with a single 16-bit, SAR ADC, ADC7605. The ADC can provide simultaneous sampling of up to four analog input signals with a ±10V single-ended input range. The board is defined as a MSOP-8 package, which consumes only 8mm×8mm area.

Application Field

The EVAL-AD7605-4SDZ is a low cost evaluation board that helps to understand the functionality of high precision SAR ADCs. The board is suited for a wide range of custom analog-to-digital conversion applications such as the industrial, automotive and consumer electronics fields.

The EVAL-AD7605-4SDZ can be used in industrial applications that require high dynamic range signal conditioning. It can be used to digitize the data from external sensors such as photo-electric sensors, potentiometers, strain gauges, torque sensors and temperature sensors. The board can also be used in single and multi-channel data acquisition systems to convert analog signals from transducers into digital signals for downstream signal processing.

The EVAL-AD7605-4SDZ can also be used in automotive applications such as motor control, engine management, body electronics, electronic brake systems and vehicle-to-vehicle communication systems. The board is suitable for applications that require low-power design, high resolution and high speed performance. The board can also be used in consumer electronics applications such as audio, video and thermal imaging.

Working Principle

The EVAL-AD7605-4SDZ operates on SAR (successive approximation register) architecture that uses an analog-to-digital converter (ADC) to convert analog input signals into digital signals. It has 16-bit resolution and operates on the principle of successive approximation. The ADC7605 registers in the device sample the analog input voltage at regular intervals and then convert it to a digital output code. The conversion starts with a comparison between the input signal and a reference voltage. If the input voltage is greater than the reference voltage, a logic one is stored in a memory element. If the input voltage is less than the reference voltage, a logic zero is stored in the memory element. This process is repeated successively until all the bits of the ADCs have been determined.

The ADC7605 features high accuracy, low power consumption and wide dynamic range. It is able to handle input signals up to ±10 V and can provide a digital output at up to 1.8 MSPS (million samples per second) sampling rate.

The EVAL-AD7605-4SDZ also features wideband bandwidth, high speed data transmission and I2C/SPI communication with up to 3.4 Mbps throughput. It also features an onboard high speed multiple-channel data acquisition system with programmable channel timing and programmable channel gain.

The EVAL-AD7605-4SDZ is an ideal evaluation board for designers looking for a high accuracy, low power and multi-channel data acquisition system. It is suitable for a wide range of analog-to-digital conversion applications in the industrial, automotive and consumer electronics fields and can provide quick and accurate results.
