OPA2335A - Brand New Texas Instruments Instrumentation OpAmps
-
Description
The OPA2335A is a CMOS operational amplifier designed and manufactured by Texas Instruments. It is a member of the OPA335 family and is utilized in instrumentation op-amp circuits. The OPA2335A requires a single power supply with a minimum voltage of 2.1V to operate. It is characterized by its low quiescent current consumption at 20µA per amplifier, low offset voltage of 125µV maximum, low input bias current of 1pA, and high open-loop gain of 115dB. The output voltage of the OPA2335A is delivered to a rail-to-rail output, with an output voltage accuracy of ± 3mV. Additionally, the OPA2335A is specifically designed for battery-powered applications. The common-mode range extending to the negative supply makes it ideal for single-supply applications. It features completely independent circuitry for low crosstalk and freedom from interaction. The OPA2335A is suitable for a wide range of applications, including portable devices, high-impedance applications, photodiode, pre-amps, precision integrators, medical instruments, and test equipment.
