Chemical Analysis & Analytical Instruments

Chemical and analytical instruments are used to test and measure the real world for human benefit. For example, this includes applications such as environmental air and water quality, material and product analysis for higher quality goods, oil and geophysical exploration, and deepening scientific discovery. Chemical analysis involves detection of light and the use of charged ion beams, redox reactions, and other technologies. Analysis methods including spectroscopy, spectrometry, and electrochemistry which implement these technologies are selected based on sample type and measurement characteristics. Accurate, high-confidence detection, identification, and characterization depends on precise sensing capability and electronics. ADI’s best-in-class signal chain, sensor, power, and processor solutions ensure that your limit of detect (LOD) and accuracy are not restricted by your electronics design.

EVAL-ADA4945-1 Circuit Diagram

EVAL-ADA4945-1 Photo

Evaluation Kits

The Analog Devices, Inc., ADA4945-1CP-EBZ evaluation board is used to evaluate the performance of the ADA4945-1 fully differential amplifier. The board can be used as either a standalone evaluation board for general purpose differential amplifier evaluation or as an amplifier mezzanine card for specified ADCs. When configured as a mezzanine card the board is easily mounted atop compatible ADC evaluation boards via the 7-pin Headers J1 and J2. This usage enables quick and easy evaluation of multiple amplifier/ ADC combinations.

The evaluation board can be configured to accept either a single-ended or differential input signal.

The board utilizes several two-pin or three-pin headers to control various features of the ADA4945-1. Headers allow the user to easily set the ADA4945-1 high and low output clamp levels, set the output common-mode voltage, choose high or low power mode, and set the digital ground level.

Optimized power and ground planes ensure low noise and high speed operation. Component placement and power supply bypassing are optimized for maximum circuit flexibility and performance. The evaluation board accepts 0402 or 0603 surface mount technology (SMT) components, 0805 bypass capacitors, and 2.54 mm headers.

EVAL-ADAQ7980 Circuit Diagram

Evaluation Kits

The EVAL-ADAQ7980SDZ is an evaluation board designed to demonstrate the low power ADAQ7980 performance and provide an easy to understand interface for a variety of system applications. The ADAQ7980 is a 16-bit, 1 MSPS, μModule data acquisition system that integrates four common signal processing and conditioning blocks into a system in package (SiP) design that supports a variety of applications

The EVAL-ADAQ7980SDZ can also evaluate the ADAQ7988, despite being populated with the ADAQ7980. To mimic the evaluation of the ADAQ7988 performance, limit the maximum sample rate of the ADAQ7980 to 500 kSPS in the ADAQ798x Evaluation Software.

The evaluation board is ideal for use with the Analog Devices, Inc., system demonstration platform (SDP) board, EVAL-SDP-CB1Z. The EVAL-ADAQ7980SDZ interfaces to the SDP board via a 120-pin connector. P1, P2, P3, and P4 SMA connectors are provided to connect a low noise analog signal source.

The ADAQ798x Evaluation Software executable controls the evaluation board over the USB through the EVAL-SDP-CB1Z. See the Related Links section for a list of on-board components

A full description and complete specifications for the ADAQ7980 are provided in the ADAQ7980/ADAQ7988 data sheet and must be consulted in conjunction with this user guide when using the evaluation board. Full details on the EVAL-SDP-CB1Z are available on the SDP-B product page.

Evaluation Kits

UG-1201 describes the evaluation board for the ADA4625-1 low noise, fast settling, single supply, rail-to-rail output (RRO), junction field effect transistor (JFET) op amp in an 8-lead small outline integrated circuit (SOIC) package with an exposed pad. The design of this evaluation board emphasizes simplicity and ease of use. This evaluation board is a 2-layer board that accommodates edge mounted SubMiniature version A (SMA) connectors on the inputs and outputs. The SMA connectors allow efficient connection to test equipment or other circuitry.

The evaluation board ground plane, components placement, and power supply bypassing are optimized for maximum circuit flexibility and performance. The exposed pad of the ADA4625-1 is connected to the ground plane on the evaluation board to enhance thermal and noise performance. The evaluation board uses a combination of surface mount technology (SMT) component case sizes 0603 and 0805, with the exception of the bypass capacitors, Capacitor C3 and Capacitor C5, which have a maximum standard size of 1206. The evaluation board also features a variety of unpopulated resistor and capacitor pads, which provide the user with multiple choices and extensive flexibility for different application circuits and configurations, such as active loop filters, transimpedance amplifiers (TIAs), and charge amplifiers.

The ADA4625-1 data sheet covers the specifications and details of the device operation and application circuit configurations and guidance. Consult the data sheet in conjunction with UG-1201 for a better understanding of the device operation, especially when powering up the evaluation board for the first time.
