description

® The LT 1097 combines low price and excellent precision performance to a new standard. In all op amp datasheets, the specifications listed on the front page are highly selective, expensive grades, while low-cost grade specifications are buried deep in the datasheet. The LT1097 doesn't have any selected grades, and the excellent specs shown in the feature section are its only achievements. The design work of the LT1097 focuses on optimizing performance, with all precision specsat supplying only 350μA. Typical values are 10μV offset voltage, 40pA bias and offset current, 0.2μV/°C and 0.4pA/°C drift. Common mode and power rejection, voltage gain is typically 128 dB excess. All important parameters, accuracy, low power op amps are optimized. Therefore, calculations using the LT1097 error budget are unnecessary in most applications.
