The TS27L4CDT is an Operational Amplifier (Op Amps) Quad Prec Low-Power, manufactured by STMicroelectronics. It is a quad precision, low power operational amplifier featuring very high DC precision, low offset voltage and guaranteed low power consumption. It offers an exceptionally low offset voltage of 0.5mV, negligible bias current, and high output current of 25mA. The TS27L4CDT is a rail-to-rail input and output amplifier with low power consumption of typically 1.7mA for all four amplifiers. It offers low input voltage noise, output noise, and current noise, making it ideal for differential and instrumentation amplifier applications. It comes in a space-saving TSOP package.
