The OPA835IDBVR is an instrumentation amplifier. It is a high precision instrumentation amplifier used mainly in transducer applications such as strain gauges, force transducers, and other sensor devices which employ Wheatstone bridge configurations. The OPA835IDBVR is a fully differential amplifier with a single power-supply, high accuracy operation and low-impedance connection configurations. OPA835IDBVR is a 16-pin DIP-packaged integrated circuit.

The OPA835IDBVR provides accurate amplifiers and buffers in one package and has two adjustable gains – one providing a fixed gain of 1 which is usually used for buffering and the second providing an adjustable gain which is typically used for instrumentation amplifiers. The gain of the adjustable amplifier section can be programmed via external resistors and the entire circuit can be powered by a single voltage source, usually an +5 volts or ± 5 volts.

OPA835IDBVR has two input channels. One of the input channels is a non-inverting input while the other is an inverting input. These two channels can be connected to two separate sensor inputs or to a single Wheatstone bridge circuit. They are then subject to a differential amplification which is controlled by the gain controlled by the gain-set resistor located on the IC itself.

The OPA835IDBVR is designed to operate at higher input levels and with lower noise than other traditional instrumentation amplifiers. It also features a low differential input voltage range of 1 mV to 5 V, and a gain-set resistor with a wide range of 10 Ω – 50 kΩ, making it suitable for a variety of transducer applications. In addition, it is highly reliable in terms of its performance over temperature, making it suitable for rugged applications.

The OPA835IDBVR is an efficient, reliable and highly accurate instrumentation amplifier for a wide range of applications such as strain gauge signal amplification, transducer signal conditioning, audio and voice signal buffering and amplification, signal level measurement and power control. Its wide range of operation and high reliability make it suitable for a variety of transducer applications and industrial measurements.
