AD8226: Wide Supply Range, Rail-to-Rail Output Instrumentation Amplifier
製品概要
The AD8226 is a low cost instrumentation amplifier that requires only one external resistor to set any gain between 1 and 1000. The AD8226 is designed to work with a very wide range of voltages. It can operate on supplies ranging from ±1.3 V to ±18 V (2.6 V to 36 V single supply). The AD8226 comes with rail-to-rail output and a wide input range that includes the ability to go slightly below the negative supply. In addition, the AD8226 inputs can withstand voltages beyond the rail.
The AD8226 is perfect for multichannel, space-constrained applications. Being a low power and low cost amplifier allows multiple channels to be used.
The AD8226 has three grades. The A grade is the lower cost version and is specified for temperatures from −40°C to +85°C. The B grade is the higher performance version and is specified from −40°C to +85°C. The C grade version is the higher temperature version and is specified from −40°C to +105°C. All models are operational from −40°C to +125°C; behavior at these temperatures is shown in the typical performance curves. The AD8226 is available in MSOP and SOIC packages.
