The AD627BRZ-R7 is a precision, rail-to-rail, instrumentation amplifier (inst amp) with low input bias current and offset voltage. It is an ideal choice for medical and industrial instrumentation applications, including medical electronics, process control, and test and measurement equipment. This inst amp features dual, low-noise, high-voltage input stages, a variable-gain stage, and a high-efficiency output stage. With a wide operating range of ±15 VDC to ±30 VDC, the AD627BRZ-R7 is capable of functioning with various system power levels. This inst amp can also be used to amplify signals in low-level circuitry, such as low-level switching applications and low-level audio circuit applications.

The AD627BRZ-R7 uses a three-stage amplifier architecture. The first stage is an input stage, which is designed to reject noise from the signal. The second stage is a gain stage, which is designed to provide an adjustable gain. The gain is adjustable from 0dB to 120dB, and the AD627BRZ-R7 has seven gain options available. The third stage is an output stage, which is designed to provide a low output impedance for driving loads. This inst amp is designed to provide very low distortion and a high signal-to-noise ratio. It also features a wide bandwidth of 1MHz to 10MHz and a low distortion of less than 0.2%.

The AD627BRZ-R7 has a slew rate of 50V/ µs and a high-current output drive of 25mA. This inst amp also features temperature coefficients of input offset voltage (VOS) of 25ppm/°C and common mode rejection ratio (CMRR) of 110dB. It is also immune to latch-up and is capable of withstanding ±40V transients at its outputs. The input and output voltage ranges of the AD627BRZ-R7 are both 0.5V to 4.9V, and the input common mode range is from –0.5V to 4.5V. This inst amp also has a unity gain frequency of 5MHz and a closed-loop output impedance of 6KΩ. The total gain nonlinearity of the AD627BRZ-R7 is 0.2%, and the device die area is 225µm×295µm.

The AD627BRZ-R7 is ideal for applications such as precision medical electronics, process control, and test and measurement equipment. It is capable of withstanding transients and offers low distortion, low noise, and high signal-to-noise ratio. The AD627BRZ-R7 also offers an adjustable gain of up to 120dB, wide bandwidth, adjustable slew rate, low distortion, and high-current output drive. Additionally, this inst amp is capable of withstanding ±40V transients, has a wide range of operating power levels, and is immune to latch-up.
