mance. The LT1354 has much lower supply current, lower ■ Unity Gain Stable input offset voltage, lower input bias current, and higher ■ C-LoadTM Op Amp Drives All Capacitive Loads DC gain than devices with comparable bandwidth. The ■ 10nV/√Hz Input Noise Voltage circuit topology is a voltage feedback amplifier with the ■ 800µV Maximum Input Offset Voltage slewing characteristics of a current feedback amplifier. ■ 300nA Maximum Input Bias Current The amplifier is a single gain stage with outstanding ■ 70nA Maximum Input Offset Current settling characteristics which makes the circuit an ideal ■ 12V/mV Minimum DC Gain, RL=1k choice for data acquisition systems.
