High Voltage Op Amplifiers ≥12V
High supply voltage op amps are used in systems that demand the widest dynamic range with the best signal-to-noise ratio. Engineers turn to Analog Devices for high voltage amplifiers that deliver industry-leading performance. Increasingly, new high voltage amplifiers also offer features to improve system performance, cost, and robustness while easing the complexity of system design. New features include integrated input overvoltage protection (OVP), on-chip electromagnetic interference (EMI) filtering, higher electrostatic discharge (ESD) immunity, and greater resistance to latch-up in both powered and unpowered operations.

Amplifier Dyno
AD-1
The AD-1 Amplifier Dyno is a tool that is designed to be used any place an amplifier exists. It can be used in a lab or production line to test true amplifier power output, quickly and easily. It is simple menu driven, does not require a computer, and cannot be cheated as the load banks are internal. It can be used in an automotive audio install shop to test true amplifier output while the amplifier is installed in the customer's vehicle.

Additional performance specs include small signal gain ranging from 9 to 14 dB, with typical noise figure of 5.5 dB. Psat levels for these amplifiers range from +16 to +25 dBm with Output IP3 levels as high as +34 dBm. All models feature single DC voltage supplies and input/output RF ports are internally matched for 50 ohms with DC blocking capacitors. These compact module assemblies require no external components and are available in rugged Kovar metal drop-in packages that are gold-over-nickel-plated and support field replaceable SMA connectors. All models are EAR99 and guaranteed to meet MIL-STD-883 test conditions for hermeticity and temperature cycle.

Basic Quad K-Type Analog Thermocouple Amplifier
SEN-30103-K1
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.

Amplifier, Switch and Test Box
CLIOQC Model V
The QCBOX Model 5 is a non-conventional unit designed to fulfil actual and future needs of an electro-acoustical analyzer like the CLIO system. It is USB linked to a PC and can be configured, with dedicated software controls, to assist frequency response and impedance measurements or to perform DC measurements. Using it for frequency response measurements acts as 50W power amplifier to drive the speaker or network under test while routing one-of-four inputs to the analyzer as well the current sensing output. The four inputs are able to provide a phantom power supply both for Audiomatica or general purpose microphones (0-24 V range, software controlled). Impedance measurements can be done either switching the D.U.T.’s load across the analyzer’s input or using a dedicated output, ISENSE, thus allowing impedance measurements in constant voltage mode as well voice coil current distortion analysis. An internal ADC measures the DC current into the voice coil. Thanks to an internal software controlled voltage generator the speaker can be driven with a superimposed DC voltage (±20V), allowing for measurements of large signal parameters. Two ADC converters with a ±2.5 V and ±5 V are available at inputs 3 and 4 to measure the displacement with a laser sensor or any other DC signal. A dedicated digital input handles an external foot pedal switch (or TTL signal) to be connected and triggers QC operations. A 6 bit output – 5 bit input TTL digital port is available to interface the QCBOX and driving software with external hardware (like turntables for example).The QCBOX Model 5 finds use both in laboratory for R&D applications and in production lines setups.
