Analog Devices Inc. ADG5412BF/ADG5413BF双方向障害保護スイッチ
Analog Devices ADG5412BF/ADG5413BF双方向障害保護クアッドSPSTスイッチは、最大−55Vおよび+55Vの双方向過電圧保護を目的とした、4つの独立制御単極/単投（SPST）スイッチが特徴です。ADG5412BFは、ロジック1入力でオンにする4つのスイッチで構成されています。その一方で、ADG5413BFには、オンにする2つのスイッチ、およびロジック1入力でオフにする2つのスイッチが含まれています。電源がオンの場合、各スイッチは両方向に同じように動作し、電源までの入力信号範囲を提供します。デジタル入力は、動作電源電圧範囲全体において3Vのロジック入力に対応します。信号範囲の重要な一部で0.5Ωオン抵抗平坦度が備わった10Ωの低オン抵抗により、ADG5412BF/ADG5413BF双方向障害保護スイッチはデータ取得に理想的に適したソリューションになり、優れた直線性および歪みの低さが重要となる切り替えアプリケーションを獲得します。
When powered on, each switch conducts equally well in both directions and offers an input signal range that extends to the supplies. The digital inputs of ADG5412BF/ADG5413BF are compatible with 3V logic inputs over the full operating supply range. When power supplies are absent, the switch remains in the off condition and the switch inputs are in a high impedance state to prevent a fault event. Under normal operating conditions, if the analog input signal levels on any switch pin exceed VDD or VSS by a threshold voltage, VT, the switch turns off. ADG5412BF/ADG5413BF block input signal levels up to +55V or −55V relative to the ground in powered and unpowered conditions.
The low on-resistance of 10Ω combined with 0.5Ω on-resistance flatness over a significant portion of the signal range make the ADG5412BF/ADG5413BF bi-directional fault protection switches ideally suited for data acquisition and gain switching applications where excellent linearity and low distortion are critical.
