借用谷歌翻译有关 TDA1034 的故事,不太顺畅,意思到了就好!
1975 – Signetics TDA1034 op-amp is introduced, the forerunner of the NE5534.. Signetics, an American IC company founded in 1961 and famous for the NE555 timer and NE565 Phase-Lock Loop, among many others, is purchased by Philips in 1975. This technology will be used in the NE5532 (dual, unity-gain compensated), NE5534 (Single, with external compensation connections) and NE5535 (dual FET-input) op amp series which will be second-sourced to become standard op-amps in the audio world for many years. The NE5535 will slowly fade away by 1990.
1975 年 – Signetics 推出 TDA1034 运算放大器,它是 NE5534 的前身。Signetics 是一家美国 IC 公司,成立于 1961 年,以 NE555 定时器和 NE565 锁相环等产品而闻名,于 1975 年被飞利浦收购。 该技术将用于 NE5532(双通道,单位增益补偿)、NE5534(单通道,带外部补偿连接)和 NE5535(双 FET 输入)运算放大器系列,这些系列将成为第二个来源,成为标准运算放大器 音频世界多年。 到 1990 年,NE5535 将慢慢消失。
