LT1990IS8 Description

Short technical summary and product information.

The LT1990IS8 is a single-channel amplifier integrated circuit engineered for precision signal conditioning in demanding environments.

 

It supports a wide operating temperature range from -40°C to 85°C and operates on supply voltages between 2.4 V and 36 V.

 

The device delivers rail-to-rail input and output capabilities, ensuring maximum dynamic range across the full supply span.

 

Key electrical characteristics include a unity gain bandwidth of 0.1 MHz, a slew rate of 0.55 V/µs, and a typical supply current of just 0.14 mA.

 

Common mode rejection ratio reaches 75 dB, while power supply rejection ratio achieves 100 dB.

 

The input stage tolerates common-mode voltages up to 250 V above the positive rail and down to 250 V below the negative rail, with a dedicated 85 V window capability at 5 V supplies.

 

Additional features include a maximum offset voltage of 0.9 mV, a gain error of 0.28%, and robust input protection rated at ±350 V.

 

Packaged in a compact SO-8 surface-mount footprint, this component is optimized for space-constrained designs requiring reliable analog front-end performance.
