Hello, As part of an insurance claim were much technical information was lost due to fire, including some operational amplifier texts, we need to either directly replace what was lost or get modern equivalents. If there is anybody that can recommend modern opamp books please help. Please do not withold recommendations on account of price. Its whats between the covers that count, and please indicate if they are academic or practical in nature. Many thanks for any help.
