AD8553:  1.8 V to 5 V Auto-Zero, In-Amp with Shutdown

Product Description

The AD8553 is a precision instrumentation amplifier featuring low noise, rail-to-rail output and a power-saving shutdown mode. The AD8553 also features low offset and drift coupled with high common mode rejection. In shutdown mode, the total supply current is reduced to less than 4 µA. Operation is fully specified from +1.8V to +5.5V.

With low offset voltage of 20µV, offset voltage drift of 0.1µV/°C and voltage noise of only 0.7µV p-p (0.01Hz 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.

The small package and low power consumption allow maximum channel density or minimum board size for space-critical equipment and portable systems. The AD8553 is specified over the industrial temperature range from -40°C to +85°C. The AD8553 is available in the lead-free 10-lead MSOP.
