The AD8553 is a precision instrumentation amplifier featuring The small package and low power consumption allow low noise, rail-to-rail output and a power-saving shutdown maximum channel density and minimum board size for mode. The AD8553 also features low offset voltage and drift space-critical equipment and portable systems. coupled with high common-mode rejection. In shutdown mode, the total supply current is reduced to less than 4 μA. The AD8553 is specified over the industrial temperature range The AD8553 is capable of operating from 1.8 V to 5.5 V. from −40°C to +85°C. The AD8553 is available in a Pb-free, 10-lead MSOP. With a low offset voltage of 20 μV, an offset voltage drift of 0.1 μV/°C, and a voltage noise of only 0.7 μV p-p (0.01 Hz to 10 Hz), the AD8553 is ideal for applications where error sources cannot be tolerated. Precision instrumentation, position and pressure sensors, medical instrumentation, and strain gauge amplifiers benefit from the low noise, low input bias current, and high common-mode rejection. The small footprint and low cost are ideal for high volume applications.
