Data Acquisition - ADCs/DACs - Special Purpose is a category for special purpose circuitry and devices tailored for specific tasks. AD7405BRIZ-RL, manufactured by Analog Devices Corporation, is a device designed for analog-to-digital conversion and sample-and-hold applications with a low power consumption. This article describes the application fields and working principle of this device.

Application Fields

The AD7405BRIZ-RL offers an impressive selection of features and performance in a very small package. It is ideal for measuring a wide variety of analog signals in industrial, medical, automotive, and consumer applications. Its unique combination of low power consumption and fast response time makes it suitable for low-bandwidth applications such as pressure sensors, proximity sensors, and temperature sensors. It is also suitable for high-speed data acquisition applications such as ultrasound and ultrasound imaging.

It can be used in a wide range of analog circuit designs. It can be used for voltage and current measurement, transducer signal conditioning, sigma-delta analog-to-digital conversion, high-accuracy and high-resolution sample and hold, data acquisition systems, and more. It is also suitable for interfacing with microcontrollers and other digital systems.

Working Principle

The AD7405BRIZ-RL uses a two-step process to convert an analog input signal into a digital word. First, a low-noise, wideband amplifier with a gain of 20 dB is used to amplify the input signal by a factor of 10. The amplified signal then enters a low-noise analog-to-digital converter (ADC). The ADC performs a resolution of 8 or 16 bit, depending on the setting of the digital configuration bits.

The unified gain-leveling and digital calibration architecture of the ADC uses a novel bit-shifting technique to eliminate gain mismatches and offset mismatches. This increases the linearity and accuracy of the conversion process. The offset, gain, and reference voltage of the ADC can be adjusted digitally, allowing the device to meet various accuracy requirements for different input ranges and reference voltages.

The AD7405BRIZ-RL has a flexible input multiplexer that can support up to eight analog inputs. The multiplexer can be configured to select any of the input channels for conversion. The low power consumption of the device and its small package size make it ideal for portable applications.

The AD7405BRIZ-RN is a programmable sample and hold amplifer (SHA) designed for high-speed measurements and data acquisition applications. It provides fast response times (< 1 ms), low-noise, and low power performance. The SHA has a low input capacitance of 200 pF and is able to accept input signals over an extremely wide dynamic range (-10 V to 10 V). It also provides numerous programmable options such as sample and hold timing, switched gain adjustment and reference voltage selection.

The AD7405BRIZ-RL is an ideal solution for embedded low-power, high-accuracy, and high-resolution data acquisition systems. Its wide range of features, small form factor, and ultra-low power consumption make it an excellent device for a variety of applications.
