ISL28191数据手册开发板套件编程器的评估板-运算放大器规格书PDF

描述 Description

The ISL28191 and ISL28291 are tiny single and dual ultra-low noise, ultra-low distortion operational amplifiers. They are fully specified to operate down to +3V single supply. These amplifiers have outputs that swing rail-to-rail and an input common mode voltage that extends to ground(ground sensing). The ISL28191 and ISL28291 are unity gain stable with an input referred voltage noise of 1. 7nV/√Hz. Both parts feature 0. 00018% THD+N at 1kHz. The ISL28191 is available in the space-saving 6 Ld UTDFN (1. 6mmx1. 6mm) and 6 Ld SOT-23 packages. The ISL28291 is available in the 8 Ld SOIC, 10 Ld 1. 8mmx1. 4mm UTQFN and 10 Ld MSOP packages. All devices are guaranteed over -40°C to +125°C.
