OPA453TA - Brand New Texas Instruments Instrumentation OpAmps
-
Description
The OPA453TA is an instrumentation opamp manufactured by Texas Instruments. It is a CMOS operational amplifier which operates on a single supply voltage as low as 2.1V.
It features a rail-to-rail output, which can drive a 100kΩ load, and ensures accuracy of the output voltage to ±3mV. The OPA453TA stands out due to its low quiescent current of 20μA/amplifier, low offset voltage (125μV max), low input bias current (1pA) and high open-loop gain (115dB).
It also features completely independent circuitry, which ensures low crosstalk and freedom from interaction. The OPA453TA is suitable for battery-powered applications and has a common-mode range that extends to the negative supply, making it ideal for single-supply applications. Some of the applications it is suitable for include portable devices, high-impedance applications, photodiode, pre-amps, precision integrators, medical instruments, and test equipment.
