TEXAS INSTRUMENTS INA129U 仪器放大器, 1个放大器, 50 µV, 4 V/µs, 1.3 MHz, ± 2.25V 至 ± 18V, SOIC
The is a low-power general purpose Instrumentation Amplifier offering excellent accuracy. The versatile 3 op-amp design and small size make this amplifier ideal for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain 200kHz at G=100. A single external resistor sets any gain from 1 to 10000. The INA12x is laser-trimmed for very low offset voltage 50µV and high common-mode rejection 120dB at G>=100. The INA12x operates with power supplies as low as ±2.25V and quiescent current is only 700µA, ideal for battery-operated systems. Internal input protection can withstand up to ±40V without damage.
