LT1722/LT1723/LT1724 Single, Dual, Quad 200MHz Low Noise Precision Op Amps FEATURESDESCRIPTION n 3.8nV/√Hz Input Noise Voltage The LT®1722/LT1723/LT1724 are single/dual/quad, low n 3.7mA Supply Current noise, low power, high speed operational amplifi ers. These n 200MHz Gain Bandwidth products feature lower input offset voltage, lower input bias n Low Total Harmonic Distortion: – 85dBc at 1MHz current and higher DC gain than devices with comparable n 70V/μs Slew Rate bandwidth. The 200MHz gain bandwidth ensures high n 400μV Maximum Input Offset Voltage open-loop gain at video frequencies. n 300nA Maximum Input Bias Current The low input noise voltage is achieved with reduced n Unity-Gain Stable supply current. The total noise is optimized for a source n Capacitive Load Stable Up to 100pF resistance between 0.8k and 12k. Due to the input bias n 23mA Minimum Output Current current cancellation technique used, the resistance seen n Specifi ed at ±5V and Single 5V by each input does not need to be balanced. n Low Profi le (1mm) SOT-23 (ThinSot™) Package The output drives a 150Ω load to ±3V with ±5V supplies. APPLICATIONS On a single 5V supply the output swings from 1.5V to 3.5V with a 500Ω load connected to 2.5V. The amplifi er n Video and RF Amplifi cation is unity-gain stable (C n LOAD ≤ 100pF). ADSL, HDSL II, VDSL Receivers n Active Filters The LT1722/LT1723/LT1724 are manufactured on Linear n Wideband Amplifi ers Technology’s advanced low voltage complementary n Buffers bipolar process.
