Instrumentation Amplifiers
Analog Devices instrumentation amplifiers (in-amps) are precision gain blocks that have a differential input and an output that may be differential or single-ended with respect to a reference terminal. These devices amplify the difference between two input signal voltages while rejecting any signals that are common to both inputs. The in-amps are widely used in many industrial, measurement, data acquisition, and medical applications where dc precision and gain accuracy must be maintained within a noisy environment, and where large common-mode signals (usually at the ac power line frequency) are present.

Basic Quad K-Type Analog Thermocouple Amplifier
SEN-30103-K0
Analog thermocouple amplifier board based on the AD849x from Analog Devices (successor of the AD597). This quad-channel thermocouple board converts the very low voltage signal from a thermocouple to a highly-linear, 0.005V/C output with either 0V or 1.245V offset (both configurations stocked) while removing unwanted noise from the signal. Many supply and output configurations are available with this board, though the PCB was designed with Arduino in mind. Specifically, the output header will plug directly into a standard Arduino Uno or Mega, with a pin-for-pin match for power supply, ground and analog outputs. With a 5V Arduino, temperatures from 0C to 1,000C are possible with the 0V offset board and -249C to 750C with the 1.245V offset board. If using a 3.3V microcontroller (Due, etc), the board must be supplied with no more than 3.3V to avoid damaging the microcontroller. Temperature measurement range is dependent on the supply voltage. It is possible to supply the board with higher voltages to allow temperature measurement over the entire operating range of the K-Type and J-Type thermocouples, allowing use with more capable data acquisition equipment.

HV200/5
The HV200/5 is a high-precision HV-amplifier designed for the control of tube scanners. It takes three input voltages In X, In Y and In Z (-10 V to + 10 V), amplifies them separately (input gain switches: x1, x2, x5, x10, x20) and adds an offset voltage between -10 V and +10 V. In a 2nd stage, the signal is amplified by a factor of 20. This enables its use as HV amplifier in scanning image acquisition applications, such as STM or AFM, with the capability to shift the scan range in high resolution imaging.

Low Voltage DC / Battery Powered HV Amplifiers
WMA-02 And WMA-02LF
The Falco Systems WMA-02 is a high voltage amplifier that runs from an 24 - 30V DC power supply and can be battery powered if required, e.g. for use in a Faraday cage. Its internal high voltage generator is inductor-free and hence does not spread magnetic interference in sensitive experimental setups. The output noise is impressively low at 4mVrms. For extremely low noise applications where bandwidth is not an issue, a dedicated WMA-02LF version is available that contains an output low pass filter capacitor which reduces the bandwidth to 50Hz, but makes the noise drop to below 0.2mVrms. This bandwidth-limited amplifier is ideal for MEMS or piezo positioning with manual voltage adjustment.

2 GHz to 6 GHz, 25 W Power Amplifier Module
HMC7748
The HMC7748 is a multistage power amplifier (PA) that provides 25 W of saturated output power across the band of 2 GHz to 6 GHz. It draws 0.7 A from a 12 V supply and up to 4 A from a 28 V supply. Input signals of as much as −8 dBm are acceptable, and the module has small signal gain of 60 dB. The 12 V supply is regulated internally and generates the negative voltage required for the gate bias. Built-in bias sequencing prevents the drain voltages for the amplifier stages from being applied without the negative voltage present, which protects the amplifiers if 28 V is applied without 12 V supply applied.
