tional amplifier with outstanding AC and DC performance. ■
2.5mA Maximum Supply Current
The LT1357 has much lower supply current, lower input ■ Unity-Gain Stable offset voltage, lower input bias current, and higher DC gain ■ C-LoadTM Op Amp Drives All Capacitive Loads than devices with comparable bandwidth. The circuit ■ 8nV/√Hz Input Noise Voltage topology is a voltage feedback amplifier with the ■ 600µV Maximum Input Offset Voltage slewing characteristics of a current feedback amplifier. ■ 500nA Maximum Input Bias Current The amplifier is a single gain stage with outstanding ■ 120nA Maximum Input Offset Current settling characteristics which makes the circuit an ideal ■ 20V/mV Minimum DC Gain, RL=1k choice for data acquisition systems. The output drives a ■ 115ns Settling Time to 0.1%, 10V Step 500Ω load to ±12V with ±15V supplies and a 150Ω ■ 220ns Settling Time to 0.01%, 10V Step load to ±2.5V on ±5V supplies. The amplifier is also ■ ±12V Minimum Output Swing into 500Ω stable with any capacitive load which makes it useful in ■ ±2.5V Minimum Output Swing into 150Ω buffer or cable driver applications. ■ Specified at ±2.5V, ±5V, and ±15V The LT1357 is a member of a family of fast, high perfor-
