TEXAS INSTRUMENTS INA105BM 差分放大器, 单位增益, 1 放大器, 250 µV, 1 dB, 1 MHz, -40 °C, 85 °C
The is a precision unity gain Differential Amplifier consisting of a precision op amp and on-chip metal film resistors. The resistor is laser trimmed for accurate gain and high common-mode rejection. Excellent TCR tracking of the resistors maintains gain accuracy and common-mode rejection over temperature. The differential amplifier is the foundation of many commonly used circuits. The INA105 provides this precision circuit function without using an expensive precision resistor network.
