Introduction to TLV9004:

The TLV9004 belongs to the TLV900x family ofOp-Amps来自德州仪器。TLV900X家族low-power, rail-to-rail input and output operational amplifiersis specifically designed for portable applications. The class AB output stage is capable of driving less than or equal to 10‑kΩ loads connected to any point between V+ and V–. The input common-mode voltage range includes both rails and allows the TLV900x devices to be used in any single-supply application.

如何使用TLV9004

The circuit shown below is an example of a single-supply photodiode amplifier circuit using the TLV9002. Trans-impedance configuration of an amplifier is typically used to convert the low-level photodiode current to a voltage signal for processing in an MCU. The transfer function between the output voltage (VOUT), the input current, (IIN) and the reference voltage (VREF) is defined in the below equation

VOUT =IN* rF+ VREF
