Product Overview The AD8538/AD8539 are high-precision amplifiers featuring extremely low offset voltage, low input bias current, and low power consumption. At a 5.0 V supply voltage, the maximum supply current for each amplifier is less than 215 μA. These amplifiers operate fully within specifications from 2.7 V to 5.0 V single supply (±1.35 V to ±2.5 V dual supply). The AD8538/AD8539's exceptionally low power consumption makes it ideal for battery-powered equipment and portable instruments. The operating temperature range for the AD8538/AD8539 is the extended industrial range (-40°C to +125°C). The AD8538 amplifier is available in a 5-pin TSOT-23 and an 8-pin narrow-body SOIC package. The AD8539 amplifier is available in an 8-pin narrow-body SOIC and an 8-pin MSOP package.
