OPA4345UA - Brand New TI Operational Amplifier
-
Description
The OPA4345UA is a CMOS operational amplifier designed for battery-powered applications. It can be operated on a 2.1V (Min.) single supply and features completely independent circuitry for lowest crosstalk and freedom from interaction. The accuracy of the rail-to-rail output voltage is ensured at ±3mV, and the device has a low quiescent current (20μA/amplifier), low offset voltage (125μV max), low input bias current (1pA), and high open-loop gain (115dB). The common-mode range extending to the negative supply makes it ideal for single-supply applications. The OPA4345UA is suitable for a variety of applications, such as portable devices, high-impedance applications, photodiode, pre-amps, precision integrators, medical instruments, and test equipment.
