very high slew rate operational amplifi ers with excellent n
6.5mA Supply Current per Amplifi er
DC performance. The LT1815/LT1816/LT1817 feature n
Programmable Current Option
higher bandwidth and slew rate, much lower input offset n 6nV/√Hz Input Noise Voltage voltage and lower noise and distortion than other devices n Unity-Gain Stable with comparable supply current. A programmable current n 1.5mV Maximum Input Offset Voltage option (LT1815 and LT1816A) allows power savings and n 8μA Maximum Input Bias Current fl exibility by operating at reduced supply current and speed. n 800nA Maximum Input Offset Current The circuit topology is a voltage feedback amplifi er with the n 50mA Minimum Output Current, VOUT = ±3V slewing characteristics of a current feedback amplifi er. n ±3.5V Minimum Input CMR, VS = ±5V The output drives a 100Ω load to ±3.8V with ±5V supplies. n Specifi ed at ±5V, Single 5V Supplies On a single 5V supply, the output swings from 1V to 4V n Operating Temperature Range: –40°C to 85°C with a 100Ω load connected to 2.5V. Harmonic distortion n Space Saving MSOP and SSOP Packages is –70dB for a 5MHz, 2VP-P output driving a 100Ω load n Low Profi le (1mm) SOT-23 (ThinSOT™) and Leadless in a gain of –1.
