The ISL28288F is a high-precision instrumentation amplifier featuring low noise, high CMRR, low-offset voltage, and low-drift. It is a fully-differential, single-ended input operational amplifier with an on-board transconductance amplifier (OPA). This amplifier is ideal for a variety of applications such as audio, data acquisition, and control systems.

The ISL28288F has a positive full-scale gain of 10 V/V. The input offset voltage is 6 µV and the offset voltage drift is 2 µV/°C. The input bias current is 1 pA while the input stage has a common-mode rejection ratio (CMRR) of 100 dB.

The ISL28288F operates on a single +5 V supply and is rated to take a maximum of 5.5 V. The quiescent current is 8 mA and the maximum output current is 8 mA. The amplifier is offered in surface-mount packages of 8-pin SOIC, 8-pin TSSOP, and 4-pin LGA.

The ISL28288F has an on-board transconductance amplifier OPA, which provides a high-precision output current with a low frequency gain of 0 V/V. The OPA is configured to provide a high-impedance input suitable for AC signals, with a common-mode rejection ratio of 100 dB for a large input voltage span. The OPA amplifier is well-suited for use in buffering high-impedance signals, such as in strain gage bridges.

The ISL28288F is ideal for use in instrumentation applications where high-accuracy and a low noise floor are required. The amplifier offers a low offset voltage and offers high accuracy across a wide temperature range. It features a high CMRR, which eliminates the need for external grounding, as well as a low input bias current, which enables accurate readings of small signals.

The ISL28288F is also suitable for use in temperature measurement systems, where high accuracy and repeatability is critical. The amplifier provides a low-drift offset voltage, which ensures stable readings over a wide temperature range. The amplifier is also well-suited for use in data acquisition and control systems, providing a high input impedance and low noise floor.

In summary, the ISL28288F is a high-precision instrumentation amplifier featuring low noise, high CMRR, low-offset voltage, and low-drift. It is suitable for use in audio, data acquisition and control systems, as well as measurement and temperature systems. Its OPA amplifier provides high accuracy across a wide temperature range, making it ideal for buffering high-impedance signals, such as in strain gage bridges.
