THS4281 极低功耗高速轨至轨输入/输出电压反馈运算放大器
Fabricated using the BiCom-II process, the THS4281 is a low-power, rail-to-rail input and output, voltage-feedback operational amplifier designed to operate over a wide power-supply range of 2.7-V to 15-V single supply, and ±1.35-V to ±7.5-V dual supply. Consuming only 750 µA with a unity gain bandwidth of 90 MHz and a high 35-V/µs slew rate, the THS4281 allows portable or other power-sensitive applications to realize high performance with minimal power. To ensure long battery life in portable applications, the quiescent current is trimmed to be less than 900 µA at +25°C, and 1 mA from –40°C to +85°C.
The THS4281 is a true single-supply amplifier with a specified common-mode input range of 400 mV beyond the rails
