AD8227是一款低成本、宽电源电压范围
Instrumentation amplifier,仅需要一个外部电阻来设置增益,增益范围为5至1000。该器件适合多种不同的信号电压。宽输入范围和轨到轨输出使信号可充分利用供电轨。由于输入范围也可以降至负电源电压以下,因此无需双电源便可放大接近地电压的小信号。该器件采用±1.5 V至±18 V电源(2.2 V至36 V单电源)供电。
The AD8227's robust inputs are designed to connect to actual sensors. In addition to having a wide operating voltage range, it can handle voltages beyond the supply rail. For example, when powered from a ±5 V supply, the voltage at the input is guaranteed to not damage the device even if it reaches ±35 V. The minimum and maximum input bias current characteristics facilitate open circuit detection. The AD8227 is ideal for multi-channel, space-constrained applications. The MSOP package and 125°C temperature rating make it promising in highly compact, airtight designs.
The AD8227 is available in 8-pin MSOP and SOIC packages and is rated for an operating temperature range of −40°C to +125°C.
