1 HA511 1MHz, Low Noise, Operational Amplifiers OBSOLETE PRODUCT POSSIBLE SUBSTITUTE PRODUCT HA2525, HA282 DATASHEET FN295 Rev 5. May 2 The HA511 is a dielectrically isolated operational amplifier featuring low noise, (.nv/ Hz at 1kHz). DC characteristics of the HA511 assure accurate performance. The.5mV offset voltage is externally adjustable and offset voltage drift is just V/ o C. An offset current of only na reduces input current errors and an open loop voltage gain of 1 x 1 6 V/V increases loop gain for low distortion amplification. The HA511 is ideal for audio applications, especially lowlevel signal amplifiers such as microphone, tape head and phono cartridge preamplifiers. Additionally, it is well suited for low distortion oscillators, low noise function generators and high Q filters.

Input Protection The HA511 has builtin backtoback protection diodes which will limit the differential input voltage to approximately 7V. If the 5 6 R P = 1k FN295 Rev 5. Page 5 of 1 May 2

6 HA will be used in conditions where that voltage may be exceeded, then current limiting resistors must be used. No more than 25mA should be allowed to flow in the HA511 s input. If saturation cannot be avoided the HA511 recovers from a 25% overdrive in about 6.5 s (see photos).
